Answer:
6.8 cubic feet
Step-by-step explanation:
7.3/4=1.825, which is the side length, 1.825*1.825=20.2575 and then ypu divide 20.2575 by 3 because it is a pyramid and that gives you 6.7525
63
5 tens equals 50
13 ones equals 13
50 +13 = 63
Step-by-step explanation:
a=16
r=3
48/16=3
144/16=3
6th term
=ar^(n-1)
= 16(3)^(6-1)

Beatrix was able to eat 21 raisins. Now, this 21 raisins is said to be 30% of the number of raisins inside the box. T
he question is, how many raisins, will there be in total inside the box?
Equation and solutions:
=> 30% = 30% / 100% = .31
=> .31x = 21
=> .31x / .31 = 21 / .31
=> x = 67.8 total number of raisins inside the box, or let's convert it to whole number

Answer:
John and Mike are correct, Henry is incorrect.
Step-by-step explanation:
Try to find x = 4 for all the equations to find out who is correct.
John:
4x + 4 + 7x = 48
Combine like terms.
11x + 4 = 48
Subtract 4 from both sides.
11x = 44
Divide both sides by 11.
x = 4
John is correct.
Mike:
2x + 3 = 11
Subtract 3 from both sides.
2x = 8
Divide both sides by 2.
x = 4
Mike is correct.
Henry:
8x + 7 = 71
Subtract 7 from both sides.
8x = 64
Divide both sides by 8.
x = 8
Henry is incorrect.
