This is a volume question. 8x8x8, 512 cubic inches of water.
You take the 4 and bring it to the power of 7
Answer:
5%
Step-by-step explanation:
We know that when there are four people, then each person gets 25% of the halwa. However, when the fifth person comes, they have everyone including the guest get 20% of the halwa. In this way, the original four people are losing 5% of their halwa in order for the fifth person to get his piece
The answer is: "
11 " .
____________________________________________________ → "
x = 11 " .
____________________________________________________Explanation:____________________________________________________Set up the ratio/ proportion as a fraction:
6 cm / 48 cm = 5 cm / (3x + 7) ;
→ The "cm" units cancel out; since: "cm/cm = 1 " ;
→ The "6/48" = "(6 ÷ 6) / (48 ÷ 6) = " 1/8 " ;
→ Rewrite as:
![\frac{1}{8} = \frac{5}{3x + 7}](https://tex.z-dn.net/?f=%20%5Cfrac%7B1%7D%7B8%7D%20%3D%20%5Cfrac%7B5%7D%7B3x%20%2B%207%7D%20)
;
Now, we can "cross-multiply" :
__________________________________________________<u>Note</u>: ![Given: \frac{a}{b} = \frac{c}{d}](https://tex.z-dn.net/?f=%20Given%3A%20%5Cfrac%7Ba%7D%7Bb%7D%20%3D%20%5Cfrac%7Bc%7D%7Bd%7D%20)
;
![ad = bc](https://tex.z-dn.net/?f=ad%20%3D%20bc)
;
{b
![\neq 0](https://tex.z-dn.net/?f=%20%5Cneq%200)
; d
![\neq 0](https://tex.z-dn.net/?f=%20%5Cneq%200)
} .
__________________________________________________ As such:
1 * (3x + 7) = 8 * 5 ;
→ 3x + 7 = 40 ;
Subtract "
7" from each side of the equation:
→ 3x + 7 − 7 = 40 <span>− 7 ;
</span>
to get:
→ 3x = 33 ;
Now, divide each side of the equation by "
3" ;
to isolate "x" on one side of the equation; & to solve for "x" ;
→ 3x / 3 = 33 / 3 ;
to get:
____________________________________________________ → "
x = 11 " .
____________________________________________________ →
The answer is: "
11 " .

Answer:
32
Step-by-step explanation:
x^2 + 4y = 16 + 20 = 32
Just do substitution.
Hope this helps.
Good Luck
