Solve the system 3x+y=7 and -2x-y=9

X=7
x=16
x=9
X=1

Step-by-step explanation:

3x + y = 7

-2x - y = 9

x = 16

answer is B

3(16) + y = 7

48 + y = 7

y = -41

answer rather than having to add and subtract the measurements of the semi-circle, notice that the semicircle to the left of ad is actually identical in area to the blank semicircle-shaped space to the left of bc. so if we transferred the red semicircle into the blank space, we would end up with a square of side length 24 cm. the area of a square is s^2 = 24^2 = 676 cm^2.
