Which matrix represents the system of equations shown below? 2x - y=-4
X-3y = 18
A
1-3 18 -3 178] -318) L* -3418)
B
с
D
2 1-472 -1 -47 [2x -y 1-47
-1 -318 1 -318 x-3y18]
O A. Matrix A
B. Matrix B
C. Matrix C
D. Matrix D

-2x + 7 = 7

subtract 7 from both sides.

-2x = 0

divide both sides by -2.

x = 0

i believe your answer is 99.7% of 7-year-old children are between 46.6 inches and 49.5 inches tall.

b.   14,375+570= 14,945

      14,945 x 5.3 = 79,208.5

      79,208.5 x 2(years) = 158,417(answer)
