Question

Solve this proportion for x. Assume c(=with slash)0 and z(=with slash)0

Answer 1

Multiply both sides by c to get x = (b/z)*c = bc/z. You can also cross multiply to get xz = bc, then divide by z to get the same answer.

Answer 2

so that mean bc/z is an answer...

Answer 3

Yup

Answer 4

Look at the rectangle at right. Find the ratio of the shaded area
to the area of the whole figure. Find the ratio of the shaded
area to the unshaded area.

Answer 5

Well, the rectangle has a length of 8 units and a width of 4 units, so the area of the whole figure is 8*4 = 32 square units. 12 out of the 32 squares are shaded, and 20 are unshaded. So, (shaded area):(whole figure) = 12/30 = 2/5 and (shaded area):(unshaded area) = 12/20 = 3/5

Answer 6

okay thank
