Answer:
C.
Step-by-step explanation:
Base area = 9 × 13
= 117 square feet
Now
Volume of pyramid = (1/3)(A)(H)
= (1/3)(117)(30)
= 117 × 10
= 1170 cubic feet
Answer:
x = 3
Step-by-step explanation:
Step 1: Simplify both sides of the equation.
5(x−3)+2x+21=3(x+4)+2x
(5)(x)+(5)(−3)+2x+21=(3)(x)+(3)(4)+2x(Distribute)
5x+−15+2x+21=3x+12+2x
(5x+2x)+(−15+21)=(3x+2x)+(12)(Combine Like Terms)
7x+6=5x+12
7x+6=5x+12
Step 2: Subtract 5x from both sides.
7x+6−5x=5x+12−5x
2x+6=12
Step 3: Subtract 6 from both sides.
2x+6−6=12−6
2x=6
Step 4: Divide both sides by 2.
Hope this helps!

What number = x
x - 3.5 = 12.7
Isolate the x, add 3.5 from both sides
x - 3.5 (+3.5) = 12.7 (+3.5)
x = 12.7 (+3.5)
x = 16.2
16.2 is your answer
