Answer: 14 pieces were not eaten.
Step-by-step explanation: 7 pizzas times 8 slices equal 56 slices total. 75% was eaten, leaving 25% or 1/4 not eaten. 1/4 of 56 or 56 divided by 4 is 14.
Answer: y = 2x
Step-by-step explanation:
The equation of a straight line can be represented in the slope intercept form as
y = mx + c
Where
m = slope = (change in the value of y in the y axis) / (change in the value of x in the x axis)
The equation of the given line is
y = 2x - 8
Comparing with the slope intercept form, slope = 2
If two lines are parallel, it means that they have the same slope. Therefore, the slope of the line passing through (- 3,-6) is 2
To determine the intercept, we would substitute m = 2, x = - 3 and
y = - 6 into y = mx + c. It becomes
- 6 = 2 × - 3 + c
- 6 = - 6 + c
c = - 6 + 6 = 0
The equation becomes
y = 2x
6+3(11)-5
6+33-5
(34)^2
1156

Answer:
I'm assuming you're multiplying, which would mean the answer is C
Step-by-step explanation:
X is unknown
Quarters 25x
Dimes 10(x+5)
Nickes 5 (x-4)
Solve for x first
25x + 10(x+5) + 5(x-4) = 470
40x + 50 - 20 = 470
40x = 440
x = 11, number of quarters
