M + w + c = 2838
w = 3c + 5
m = 4w - 3......4(3c + 5)- 3 = 12c + 20 - 3 = 12c + 17
(12c + 17) + (3c + 5) + c = 2838 .....combine like terms
16c + 22 = 2838
16c = 2838 - 22
16c = 2816
c = 2816/16
c = 176 <==== children
w = 3c + 5
w = 3(176) + 5
w = 533 <=== women
m = 12c + 17
m = 12(176) + 17
m = 2129 <=== men
First quiz in social studies as in the second one it was only 90%
Answer:
d. −7/32
Step-by-step explanation:
The expression that we have to evaluate in this problem is:

We have to evaluate this expression for:
x = -2
y = 4
We start by rewriting the expression by rewriting it using the following:

So the expression can be rewritten as

Now we observe that:

Therefore, by substituting x = -2 and y = 4 into the expression, we find:
