Answer: 7 pounds of sugar cookies
X+Y+Z = 20
4x + 3y +4.50z = 77
-x + y + 0z = 2
X+Y+Z = 20 4x + 3y + 4.50z = 77
-x + y +Oz = 2 (-x + y + 0z = 2) x 4 (-4x +4y+0z=8)
Add the problems vertically
0x + 2y + z = 22 0x +7y + 4.50 z = 85
Rewrite the problem
2y + z = 22 (Times 7)
7y + 4.50 = 85 (Times -2)
14y +7z = 154
-14y - 9z = -170
Add Vertically
-2z = -16
divide by -2
z = 8
there are 8 Chocy Chips
if we plug 8 for z in 2y + z = 22 we get y = 7
making 5 be X (Cause X+Y+z = 20)
8 Chocy
7 Sugar
5 Peanut butter

6. Three bunches of flowers can be bought for $9.48. Four bunches can be bought for $10.64. Which is the better buy?
slope and y intercept for 2y-8=6x
Answer:
slope = 3
y intercept = 4
Step-by-step explanation:
Rearrange the equation so y is the subject.
1. Add 8 to both sides
2y = 6x + 8
2. Divide both sides by 2
y = 3x + 4
Voilà, you got your answer in the line format, y = mx + c, where m is the slope and c is the y intercept.
brian says that 8n+2=82 when n=1 explain why he is incorrect
Slope is represented by the letter ____________ and the y-intercept is represented by the letter _______________ and is where the graph ________________________________
Answer:
Slope is represented by the letter M and the y-intercept is represented by the letter B and is where the graph intersects the y axis.
Step-by-step explanation:
y = mx+b, where y and x are variables and m is the slope and b is the y-intercept

Answer:
x = 9/5 or 1.8
Step-by-step explanation:
Answer: Or 9/5 Have a great day :)
Step-by-step explanation:
-3x+18= 7x
18+= 10x
x= 18/10
x= 9/5
An airplane flies with a constant speed of 768 km/h. How far can it travel in 50 minutes
Answer:840 km/h divided by 60 = 14km/min
3 x 60 = 180
180 + 20 = 200 minutes total
14 x 200 = 2800km
that is a really awkward way of doing it though. really you can just do:
840 x (10/3) = 2800km
Step-by-step explanation:
y = - 4x + 3 & x - 4y = 8 : parallel or perpendicular or neither
Answer:
perpendicular
Step-by-step explanation:
Parallel lines have equal slopes
The product of the slopes of perpendicular lines = - 1
The equation of a line in slope- intercept form is
y = mx + c ( m is the slope and c the y- intercept )
y = - 4x + 3 ← is in slope- intercept form
with slope m = - 4
x - 4y = 8 ( subtract x from both sides )
- 4y = - x + 8 ( divide through by - 4 )
y = [tex]\frac{1}{4}[/tex] x + 2 ← in slope- intercept form
with slope m = [tex]\frac{1}{4}[/tex]
Since the slopes are not equal the lines are not parallel
- 4 × [tex]\frac{1}{4}[/tex] = - 1
Then the lines are perpendicular
rewrite in simplest form

Answer:
I'd say the answer is cube of a binomial, because when something is specifically raised to the 3rd power, that number is being cubed. (When you square a number it has an exponent of 2, whereas when you cube a number it has an exponent of 3.)

Find the angle measure.
The measure of the angle is ?
Answer:
133°
Step-by-step explanation:
The angle X is the same as the given.
[tex]\mathbb{ANSWER:}[/tex]
⇒ The two parallel lines are cut by a transversal so the interior angles on the same side of a transversal are congruent. This means that the measurement of the second angle is also 133 degrees.
Hence, the measurement of the angle is also 133 degrees.

20. The table shows the numberof days you keep a rented movie before returning it and the total cost of renting the
movie. Find the rate of change in cost with repect to time and interpret its meaning.
Time (days)
4
5
6
Cost (dollars)
6.00
8.25
10.50
Step-by-step explanation:
According to given table we have pairs of points:
(4, 6.00), (5, 8.25), (6, 10.50)The rate of change is:
(8.25 - 6.00)/(5 - 4) = 2.25or
(10.50 - 8.25)/(6 - 5) = 2.25It is 2.25 and the meaning is:
Rental per day is $2.25In the table, how can I get from 8 km to 1 km?
A. Multiply by 8.
B. Divide by 8.

How do you write 17/5 as an mixed number
Answer:
3 2/5
Step-by-step explanation:
17/5= 3 2/5
Answer:
First find the nearest number divisible by 5 to get a whole number returned
that number is 15
15/5 = 3 (no decimals)
so the ‘big’ (as I like to call it) number or the integer that isn’t part of the fraction would be 3.
now what is left?
subtract 15 from the numerator
17 - 15 = 2
replace 17 with 2 in the fraction to get 2/5
The result is [tex]3\frac{2}{5}[/tex]
to prove this is the same
multiply the ‘big number’ by the denominator
3*5 = 15
and add the numerator
15+2 = 17
now just insert the denominator below it, and you get 17/5
What is the distance between −93 and 114 on a number line?
Answer:
207
Step-by-step explanation:
By counting the amount of numbers to get from -93 to 114, you count a total of 207. This means it takes 207 steps to get from -93 to 114.
When finding the distance between negative and positive numbers you can also add the numbers together to get the total distance between the numbers.

PLEASR HELP MEEEE ASAP
Answer:
A: Yes, I agree. Why? Because if you look at the shape, its a triangle right, and a triangle both sides are equal, while the bottom line is not. But because both sides are equal, and half of the triangle is MPN and the other side is QPN, they both are congruent (or equal to)
B: Like I said, both MPN and QPN are both equal, and if you remove the P, it would still be the same because the shape has not changed.

9.) During the soccer season, Finn scored goals on 8% of the shots he
took. If he scored 40 goals, how many shots did he take?
1 point
500 shots
50 shots
320 shots
32 shots
Answer:
500 shots
Step-by-step explanation:
the question is 8% of what number is 40?
we can use this proportion: is/of = %/100
let 'g' = number of goals
40/g = 8/100
cross-multiply to get:
8x = 4000
x = 500

A painter charges $15.80 per hour, plus an additional amount for the supplies. If he made $190.89 on a job where he worked 7 hours, how much did the supplies cost?
A.
$110.60
B.
$80.29
C.
$90.29
D.
$27.27
Answer:
B
Step-by-step explanation:
First find out how much he made without the supplies. To do this you would multiply $15.80 by the 7 hours he worked. This gives you 110.60. Then subtract 110.60 from the 190.89 the job cost. You would then overall get 80.29 for the supplies
