Answer:
Marissa did not change the direction of the inequality sign.
Step-by-step explanation:
Hello!
We can solve the inequality as well, and compare our steps to Marissa's to verify her steps.
Solve the inequality:[tex]-\frac x{12} > 7.8[/tex][tex](-12)\frac{x}{-12} > 7.8( -12)[/tex][tex]x < -93.6[/tex]We have the same number, but a different inequality sign. This is because we have to flip the inequality sign when multiplying and dividing by a negative number.
Therefore, the answer is the last option, Marissa has to flip the inequality sign when multiplying by a negative number.

In the table, we see a rate of change of 5 when multiplying by the bag of screws to get the price:
2 • 5 = 10
4 • 5 = 20
7 • 5 = 35
Because all of the equations are true, we know the relationship between the number of bags of screws and the price is proportional.
Answer: proportional
Step-by-step explanation:
if you divide 10 by 2 you get 5.
since 4 times 5 is 20 and 7 times 5 is 35
the table is proportional since there is a set rate of change

What is the maximum number of 2cm cubes that can fit into a box measuring 10cm by 8cm by 5cm?
Answers
Answer: The volume of box is 6×8×10 cm^3
All of 6,8 and 10 are divisible by 2 so your cubes will fill the box, the volume of the cube is 2×2×2=8 cm^3 divide the volume of the box by 8; number of cubes fitting in the box is 6×10=60
Step-by-step explanation:All of 6,8 and 10 are divisible by 2 so your cubes will fill the box, the volume of the cube is 2×2×2=8 cm^3 divide the volume of the box by 8; number of cubes fitting in the box is 6×10=60
Answer:
50 cubes
Step-by-step explanation:
The maximum number of 2cm cubes that can fit into a box measuring 10cm by 8cm by 5cm is 50 cubes.
You can find this by dividing the total volume of the box (10 x 8 x 5 = 400 cm^3) by the volume of a single cube (2 x 2 x 2 = 8 cm^3). So 400cm^3 / 8cm^3 = 50 cubes.
Hence, The maximum number of 2cm cubes that can fit into a box measuring 10cm by 8cm by 5cm is 50 cubes.

Carter wants to ride his bicycle 28.7 miles this week. He has already ridden 17 miles. If he rides for 3 more days, write and solve an equation which can be used to determine mm, the average number of miles he would have to ride each day to meet his goal.
Answers
Answer: Carter will have to ride 3.9 miles on his bicycle every day in order to achieve his goal.
Step-by-step explanation:
Finding the answer to this problem isn't too complicated, and all we have to do is make and solve an equation. First, we know how many miles Carter wants to ride his bicycle (this is what our equation will be equal to), and how many miles he's completed already (we add that to how many he has to do daily). We also know how many days he has left to complete this goal (multiply the number he has to do daily by three).
All we have to do now is construct a basic equation:
17 + 3x = 28.7
Let's move the 17 over to the other side of the equation. To do that, subtract 17 from both sides.
3x = 28.7 - 17
3x = 11.7
This gives us the amount of miles Carter still has to ride - in total. To find out how many miles he has to ride daily, we just divide 3 from both sides.
3x/3 = 11.7/3
x = 3.9 (miles - don't forget the units!)
Carter will have to ride 3.9 miles on his bicycle every day in order to achieve his goal. Hope this helps!
Which graph shows the solution to the system of linear equations?
y equals one third x
x + 3y = −6
Answers
Answer:So let's start by guesstimating the slopes:
the green line has a slope close to -x, but more negative than that, possibly -2; the pink line has a slope close to +x, but higher towards +2.
Next let's look at the solution: the two lines intersect at the point (1, -1).
**you could just simple plug that x (1) into all the equations, but let's rule out answers anyway. ;)
A) is incorrect because the slopes of -1 and +1 are off from out predicted -2 and +2
B) is incorrect because of a similar reason, the slopes of +3 and +1 don't make any sense
C) Ooh, we do have a +2 and -2 for the slopes, and... violà! plug in 1 for the x's and we get -1 for the y in both equations
D) slopes are closer than in A and B, but plugging in 1 doesn't get us -1
So the correct answer is:
C) y = 2x - 3 and y = −2x + 1

Kado spent 1 2/3 hours painting a fence. Then he spent 4/5 of an hour walking his dog. How much longer did he spend painting than walking? Orleans chose C as the correct answer.How did she get that answer?
Answers
Answer: B, 13/15
Step-by-step explanation: If you multiply both to 15, you will get 1 10/15 and 12/15 if you then subtract the two of them you will be left with
13/15.
Orleans might have got the answer from subtracting wrong or adding them together.
Hope this helps! :)
Orleans must have chosen C as the correct answer, which is 13/15 hours. This means that Kado spent 13/15 hours longer painting the fence than walking his dog.
To find out how much longer Kado spent painting than walking his dog, we need to calculate the difference between the time he spent painting and the time he spent walking his dog.
Kado spent 1 2/3 hours painting the fence.
He spent 4/5 of an hour walking his dog.
To make the calculation easier, let's convert 1 2/3 hours into an improper fraction:
1 2/3 = (3*1 + 2)/3 = 5/3 hours
Now, the time difference is:
Time spent painting - Time spent walking
= (5/3) - (4/5)
To subtract fractions, we need to find a common denominator, which in this case is 15 (the least common multiple of 3 and 5):
= (5/3)(5/5) - (4/5)(3/3)
= 25/15 - 12/15
Now, we can subtract the fractions:
= (25 - 12)/15
= 13/15 hours
Orleans must have chosen C as the correct answer, which is 13/15 hours. This means that Kado spent 13/15 hours longer painting the fence than walking his dog.

janet bought a dress for $245. she recived a 15% discount vecause she is a loyal customer. in addition she recived another 10% off. calculate janets final bill
Answers
Multiply .15 * 245 =$36.75 ok that’s the first discount!
Second discount is 10% so turn 10% into a decimal (by dividing your percentage by 100) = .10
Multiply .10*245= $24.50 <- that’s your second discount
Ok now take both those answers and subtract them from her original $245 bill.
245-(24.50+36.75)= $183.75
Her final bill is $183.75
Charlie bought pound of American cheese and pound of Swiss cheese. Josh bought pound of cheddar cheese and pound of jack cheese. Josh says that they bought the same amount of cheese. Is he correct? Explain.
Answers
Answer: It is not possible to determine whether Josh is correct without more information. In order to determine whether they bought the same amount of cheese, it would be necessary to know the weight of the cheeses that Charlie and Josh bought. If the weight of the cheeses that Josh bought is equal to the weight of the cheeses that Charlie bought, then Josh is correct and they did buy the same amount of cheese. However, if the weight of the cheeses that Josh bought is not equal to the weight of the cheeses that Charlie bought, then Josh is incorrect, and they did not buy the same amount of cheese.
Step-by-step explanation: It's hard to say because you would need the weight of the cheese.

The relative frequency of the columns are:
Group 1 Group 2 Group 3
Category 1 4/11 1/4 11/19
Category 2 7/11 3/4 8/19.
What is the frequency?
The number of times a specific value appears in the data is its frequency (f). A variable's distribution is its frequency pattern, or the collection of all conceivable values and the frequencies corresponding to those values. Frequency tables or charts are used to represent frequency distributions.
Given table is
Group 1 Group 2 Group 3
Category 1 4 3 11
Category 2 7 9 8
The frequency of group 1 is (4+7) = 11
The frequency of group 2 is (3+9) = 12
The frequency of group 3 is (11+8) = 19.
The relative frequency is the ratio between the number of times an outcome value appears in the set of all outcomes and the total number of outcomes.
Group 1 Group 2 Group 3
Category 1 4/11 3/12 = 1/4 11/19
Category 2 7/11 9/12 = 3/4 8/19.

4(x-1)+9=17
Step-by-step explanation:
3(-2x+1) + 5 = 3x-4-5x
expand
-6x + 3 + 5 = 3x-4-5x
-6x + 8 = -2x - 4
add 2x to both sides to put all x values + coefficients on one side
-4x + 8 = -4
subtract 8 from both sides to isolate x and its coefficient
-4x = -12
divide both sides by -4 to isolate x
x = 3
plug x=3 into each option to see if it works
1. 5(3+3)-4 = 30-4 = 26 != 10
2. 2(3+1) = 8 != 4
3. 4(3-1)+9 = 17 = 17
4. 4(3)+7 = 19 != 3+8 = 11
