(A) 28 . Thanks for the question hope this helps
-15x - 3y = 3
-15x - 3(5x-1) = 3 [input y]
-15x - 15x - 3 = 3 [distribute 3 over 5x and -1]
-30x - 3 = 3 [combine like terms]
-30x = 6 [add 3 to eliminate the negative]
x =

[divide by -30 to get x alone]
x =

[reduce the fraction]
Hopefully this is helpful enough to get you to your answer
Answer:
C im pretty sure
Step-by-step explanation:
Because the square taken out has a 4x4 area which is 16 and the area of the whole square used to be 14x14 which is 196 and if u subtract 16 from that you get 180
Answer:4
Step-by-step explanation:2x+y+z=2(-2)+3+5=(-4)+3+5=(-1)+5=4
Its C because the 18in is the height, the 12in is the width, the 24in is the length. Which you just multiply together.
