A) P + E = 20B) 2*P + .40*E = 32.50Multiplying A) by -2A) -2P -2E = -40 then we add equation BB) 2*P + .40*E = 32.50-1.6E = -7.50The answer does not equal an integer. Is the problem typed correctly?
Im assuming that to be the case, so:-
11/12 + 1 3/4
= 11/12 + 7/4
= 11/2 + 21 / 12
= 32 / 12
= 2 2/3 OZ. (Choice D).

The formula u should use us 3(bxh divided by 2) then for the smaller triangle just bxh divided by 2 bcuz the other 3 will have the same base and height but the last one doesn't
63+38= 101
180-101= 79
9x=81
x=9
