Answer:
x = -10/13
Step-by-step explanation:
10x + 7 = -3x - 3
Add 3x to both sides
10x + 3x + 7 = -3x + 3x - 3
13x + 7 = 0x - 3
13x + 7 = -3
Subtract 7 from both sides
13x + 7 - 7 = -3 - 7
13x + 0 = -10
13x = -10
Divide both sides by 13
13x ÷ 13 = -10 ÷ 13
1x = -10/13
x = -10/13
B=3d and b=d+4
Since b=b we can say:
3d=d+4 subtract d from both sides
2d=4 divide both sides by 2
d=2

Answer:
h = 8
Let the unknown number be h for height
V = LWH
984 = 20.5 x 6 x h
984 = 20.5 x 6h
984 = 123h
984 ÷ 123h
= 8
