y = x + 4
move +4 to the other side
sign changes from +4 to -4
y-4= x+4-4
y-4= x
Answer:
x=y-4
12 x 6 equals 72 so 72 + 7 = 79 :)
Your answer is 79
Y=52x + 48
for 6 boxes: 52(6) + 48 =360 dollars
for 20 boxes: 52(20) +48= 1,088 dollars
hope this helps :)
if this trapezoid is to scale, then the scale factor between the shortest and longest side is 1.5
so, that means that 1.5(2x+6) = 4x+2
so, your equation becomes 3x+9 = 4x+2
if you subtract 2 from each side, you get 3x+7 = 4x
meaning that x = 7
i hope this helps, and i'm sorry if it's wrong!! :)
therefore there are no solutions in real numbers.
