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
Answer:
90428160.3 ft³
Step-by-step explanation:
The question is on volume of a pyramid with a square base
The formulae for volume of a pyramid is V=( l×w×h)/3
where l is length of pyramid base, w is width of pyramid base and h is the height of the pyramid
The pyramid has a square base thus l=w= 751 feet
The height of the pyramid is h=481 feet
v= (751×751×481)/3
v=90428160.3 ft³
