So we know that there are 8 slices per large pizza (7), so a total of 56 slices
we would set up a proportion
5/8=x/56
8 times 7 gives you 56, and we would do that same thing to the 5 (multiply it by 7) to get 35?
so now we know that 35 out of 56 slices were eaten
56-35 is 21
so there are 21 slices left over

3. The width of a rectangle is 4 feet less than the length. The area is
mina [271]

Answer:

L = 6, w = 2

Step-by-step explanation:

Let w = width of rectangle

Let L = length of rectangle

w = L - 4

Area of rectangle = Lw

L (L - 4) = 12

L^2 - 4L = 12

L^2 - 4L - 12 = 0

(L - 6)(L + 2) = 0

L - 6 = 0

L = 6 (the other option doesn't work because dimensions can't be negative)

w = L - 4

w = 6 - 4

w = 2

Double check

A = Lw

A = 6 x 2

A = 12

It matches so we are right.

Line f has a slope of −6/3, and line g has a slope of −8/4.
Nataliya [291]

Answer:

The option A) is correct

"The lines have proportional slopes" is correct

Therefore the given slopes are proportional to each other

Step-by-step explanation:

Given that Line f has a slope of \frac{-6}{3}, and line g has a slope of \frac{-8}{4}

Also given that f and g are distinct lines

To check the proportionality of two slopes :

\frac{-6}{3}=\frac{-8}{4}

-2=-2

2=2

Therefore the given slopes are proportional to each other

Therefore option A) is correct

"The lines have proportional slopes" is correct
