Answer:
13 it is very easy
Step-by-step explanation:
first subtract the last equation from the first. this gives:-
-x + y = -8 .....................(1)
Then multiply the first equation by 2 and add it to the 2nd equations This gives
9x = 18
so x = 2
and from equation (1) y = -8 + 2 = -6
Substituting for x and y in the second equation
z = (24 -5(2) -12) / 2 = 1
Answer is choice b.
A = 1/2(a+b)*h = 1/2(20+16)*10 = 18*10= 180 yd^2
Answer is A... 0.25
2 1/2 = 2.5
2.5/10 = 0.25
hope it helps
