What is the independent variable (x) for this situation?
number of cases of paper
not enough information to determine independent quantity
cases of paper per tree
number of trees used
trees used per case of paper
Answer:
The independent variable would be
trees used per case of paper
Step-by-step explanation:
Answer:
Number of trees used
Step-by-step explanation:
The number of trees used is the independent variable because it doesn't depend on anything, meaning it isn't changed by other variables. The number of cases of paper would be the dependent variable because it depends on the number of trees used.
What is the slope of the line? *
Answer:
- 1.5
Step-by-step explanation:
I suggest to make a table
x y
-2 3
2 -3
from 3 to -3, you subtract 6
from -2 to 2, you add 4
so y/x
-6/4 = -1.5
Slope is -1.5

Jamal and Samuel are saving for a camping trip. Jamal starts with $18 and saves $5 each week. Samuel starts with $10 and saves $7 each week. Use the drop-down menus to complete the rule for the amount of savings for each boy.
Answer:
4 weeks
$28
Step-by-step explanation:
Let
x = number of weeks
Jamal's savings = 18 + 5x
Samuel's savings = 10 + 7x
Equate both savings
Jamal's savings = Samuel's savings
18 + 5x = 10 + 7x
18 - 10 = 7x - 5x
8 = 2x
x = 8 / 2
= 4
x = 4 weeks
Check:
18 + 5x
18 + 5(2)
18 + 10
= $28
Each boy would have saved an equal amount of $28 at the end of the 4th week
Which of the followin statements are true about the equation 10x + 45x - 13 = 11(5x + 6) *
Step-by-step explanation:
The given expression is :
10x + 45x - 13 = 11(5x + 6)
We can simplify it as follows :
Opening parenthesis on RHS
10x + 45x - 13 = 55x + 66
Taking like terms together,
55x-55x = 13+66
0 = 13+66
The given expression has no solution, as the variable cancels out woh each other. It is a meaningless expression.

In the diagram below of triangle ABC, DE is parallel to AC. IF AD = 20, DB = 10 and AC = 33, find DE.
Answer:
11
Step-by-step explanation:
It's proportions my son.
x / 33 = 10 / 30
It's 10/ 30 because the whole BA is 30 in total
Then cross multiply.
30x = 330
x = 11
1. The printed price of a DVD player is $ 7500. If a sales tax of 8% is realised from the buyer, find the price at which the DVD player is sold?
Answer:
11 % of 3rds into 8
Step-by-step explanation:
Answer:
8100
Step-by-step explanation:
printed price = $7500
sales tax = 8%
selling price of DVD
= 7500 + 8% of 7500
= 7500 + 600 = $8100
Answer: DVD was sold for $8100
16. Peter was told by his teacher that he needed to measure the height of the building in which his
classroom was located. He backs away from the building and places a mirror on the ground
between him and the wall. When he can see the top of the building in the mirror, Peter is 2 feet
9 inches away from the mirror and the mirror is 11 feet away from the wall of the building. Peter
knew his eye level was exactly 5 ft 6 inches off of the ground, so he was able to calculate the
height of the building. How tall is the building in feet?
Answer:
IT'S 20 FEET JUST FOUND OUT

Answer:
x=-1
Step-by-step explanation:
Step 1: Subtract x from both sides.
−x+4−x=x+6−x
−2x+4=6
Step 2: Subtract 4 from both sides.
−2x+4−4=6−4
−2x=2
Step 3: Divide both sides by -2.
−2x/−2= 2/−2
x=−1

Solve for x and y
60°
у
Х
30°
73
Answer:
x=7
y=14
Step-by-step explanation:
this is a special 30-60-90 right triangle bc there is a right angle marker and a 60 degree and 30 degree angle
in 30-60-90 right triangles the short leg is x, the long leg is x√3, and the hypotenuse is 2x
it is given that the long leg is 7√3, and since the long leg equals x√3, then x equals 7
so the short leg, x, is 7 and since the hypotenuse is 2x, 2(7) =14
The graph of f(x) = 4x3 – 13x2 + 9x + 2 is shown below.
On a coordinate plane, a function is shown. The function starts from the bottom of quadrant 3 and goes up through the x-axis at (0, negative 0.25) and then through the y-axis at (0, 2). It then starts to curve down at (0.5, 4) until it reaches (1.75, negative 0.5). It then curves up and crosses the x-axis at (2, 0) and goes up approaching x = 3.
How many roots of f(x) are rational numbers?
0
1
2
3
Answer:
3
Step-by-step explanation:
f(x) = 4x^3 – 13x^2 + 9x + 2
This looks complicated but all we need to find are the Roots
We are looking for when y=0
So given each part of the information, we can label how many times it happens
The function starts from the bottom of quadrant 3: Starts lower left
and goes up through the x-axis at (0, negative 0.25) : This is ONE ROOT
and then through the y-axis at (0, 2). : It's now on the 2nd quartile
It then starts to curve down at (0.5, 4): It's moving towards y=0
until it reaches (1.75, negative 0.5).: It has now passed y=o and there are TWO ROOTS
It then curves up and crosses the x-axis at (2, 0) and goes up approaching x = 3: It has passed y=0 again, so there are THREE ROOTS
This polynomial function has 3 ROOTS

First, divide 108 by 12.
The result is 9.
Now square root 9.
The result is 3.
Now, multiply 12 by 3.
The result is 36.
To check that this is the pattern, we multiply 36 by 3, and we indeed see that 3 times 36 is equal to 108.

StartFraction 1 Over 12 EndFraction of a pound StartFraction 1 Over 9 EndFraction of a pound One-fourth of a pound One-third of a pound
Answer:
[tex]Each\ Weight = \frac{1}{4}[/tex]lb
Step-by-step explanation:
Given
[tex]Weights = \frac{3}{4}lb[/tex]
[tex]Bananas = 3[/tex]
Required
Determine the weight of each
To do this, we simply divide the total weight by the number of bananas.
[tex]Each\ Weight = \frac{3}{4}/3[/tex]
Convert to multiplication
[tex]Each\ Weight = \frac{3}{4} * \frac{1}{3}[/tex]
[tex]Each\ Weight = \frac{1}{4}[/tex]
Hence, each banana weighs 1/4 of a pound

1) In a bag of red and green sweets, the ratio of red sweets to green sweets is 3:7. If the bag contains 49 green sweets, how many red sweets are there?
Answer:
Red sweets = 21
Step-by-step explanation:
Let there are 3x red sweets and 7x green sweets.
Total no of 49 green sweets.
ATQ,
7x = 49
x = 7
Red sweets = 3x
= 3(7)
= 21
Hence, there are 21 red sweets.
Zoey made 6 1/2 cups of trail mix for a camping trip. She wants to divide the trail mix into 3/4 cup of servings. Twelve people are going on the camping trip. Can zoey make enough 3/4 cup servings so that each person on the trip has on serving?
Answer:
No
Step-by-step explanation:
Given that:
Total number of cups of trail mix available for camping trip = [tex]6\frac{1}{2}[/tex]
Amount of one serving contains = [tex]\frac{3}{4}[/tex] cups
Number of people at the trip = 12
To find:
Whether each person will be able to get the servings?
Solution:
Here, we can find the total number of servings by dividing the total number of cups of trail mix with the amount of one serving.
First of all, let us convert the mixed fraction into fractional number.
[tex]6\dfrac{1}{2} = \dfrac{6\times 2+1}{2} = \dfrac{13}{2}[/tex]
Therefore, total number of servings available as per the given quantities:
[tex]\dfrac{\frac{13}2}{\frac{3}4}\\\Rightarrow \dfrac{13\times 4}{2\times 3} \\\Rightarrow \dfrac{26}{3}\\\Rightarrow \approx 8[/tex]
So, With this type of servings Zoey will be able to serve only 8 people.
Therefore, there is not enough servings.
10/3 = x divided by -5/2
x =?
Answer:
-0.3x
Step-by-step explanation:
if you divide all of the number up you will get -0.3x
Answer:
Not possible
Step-by-step explanation:
The reason why its not possible is because to figure out a x type of problem, there needs to be a answer to it.
Lets try it solve it to make better sense.
10/3 = 3.33333333333
-5/2 = -2.5.
Divide.
= -1.33333333333.
If this is possible, the answer is -1.33333333333.
Fraction = -4/3.
