The equation that can be used to determine the tax rate, x is ;44.31 = 42 + (x% of 42) where x = 5.5%
<h3>How to write equation</h3>
- Cost of a shirt = $12.50
- Cost of each shorts = $14.75
- Cost of two shorts = 2 × $14.75
= $29.5
- Total cost = $12.50 + $29.5
= $42
- Total amount paid = $44.31
Total = total cost + x% of total cost
44.31 = 42 + (x% of 42)
44.31 = 42 + 42x/100
44.31 - 42 = 42x/100
2.31 = 42x / 100
x = 2.31 ÷ 42/100
= 2.31 × 100 /42
= 231/42
= 5.5%

Answer:A
Step-by-step explanation:
first you use the lmnp and pqno to get our full answer
Answer:x=-8
Step-by-step explanation:
12(x/4+2/3)=12(x/6)
3x+8=2x
3x-2x=-8
x=-8

I wish I were those kids
Answer:
Both are correct.
Step-by-step explanation:
The key understanding here is that you can factor a monomial in many different ways!
To check if any of the factorizations is correct, we can multiply the factors and see if their product is really 12x^712x

12, x, start superscript, 7, end superscript.
Hint #22 / 4
\begin{aligned} (\blueD{4}\maroonD{x^3})(\blueD{3}\maroonD{x^4})&=(\blueD{4})(\blueD{3})(\maroonD{x^3})(\maroonD{x^4}) \\\\ &=\blueD{12}\maroonD{x^7} \end{aligned}

So Ibuki is correct!
Hint #33 / 4
\begin{aligned} (\blueD{2}\maroonD{x^6})(\blueD{6}\maroonD{x})&=(\blueD{2})(\blueD{6})(\maroonD{x^6})(\maroonD{x}) \\\\ &=\blueD{12}\maroonD{x^7} \end{aligned}
