so a whole is same/same, in this context is 4/4 = 1, or four fourths.
now, we know 1/4 failed, that means 4/4 - 1/4 = 3/4 didn't fail, so 3/4 passed.
from that remaining 3/4, how many got an A? well 1/3, how much is 1/3 of 3/4? well is just their product, .
so 1/4 of the remaining 3/4 got an A, that means 3/4 of the remaining 3/4 did NOT get an A.
how much is 3/4 of 3/4? well, is just their product.
Answer:
x = 12.8
Step-by-step explanation:
To find the value of x, set up a proportion between the two similar triangles. Then solve for x.
Solve by cross multiplying and isolating x.
32(56) = 40(32+x)
1792 = 1280 + 40x
512 = 40x
12.8 = x
