Answer:
96
Step-by-step explanation:
ok you will times 120 with 80% and divide that answer with 100
Y -3x = 7 from this result y = 7 +3x what value of y we need substituting in place of y inside second equation and will get
21 +9x = 3y
21 +9x = 3(7 +3x)
21 +9x = 21 +9x
0 = 0
so this mean that there are an infinite number solutions so choice B. is right
380-140 is 240 and 240 divided by 2 is 120 and that's the width, 120
