Answer:
D. 60
Step-by-step explanation:
4(3x + 3) = 5(x + 8) 12(4) + 12 5(4) + 40
12x + 12 = 5x + 40 48 + 12 20 + 40
-5x -5x 60 60
7x + 12 = 40
-12 -12
7x = 28
x = 4

Answer:
x=2
y=10.5
z=2.3
w=1.75
Step-by-step explanation:
both sides of each scale have the same weight attached to them so you just have to solve the following equasitions for each scale: 3x+1=7 2y+10=31 2z+2.2=6.7 4w+3/2=17/2
7,000+500+2
2(3751)
7x10^3+5x10^2+2X10^0
5(1500.4)
