<u><em>Answer:</em></u>
4 chairs
<em><u>Step-by-step explanation:</u></em>
Start with 2/3 can of paint: (2/3)
He used 1/6 of the can to paint each chair: (divided by 1/6)
Now use the 'keep, change, flip' method to get the expression: (2/3x6/1)
Then simplify your answer: (12/3)
Lastly simplify again: (4)
Thus, he painted 4 chairs.
<em>9)</em>
<em>- 12xy/7x⁴ × 21x⁵y²/4y = - 9x²y²</em>
<em>10)</em>
<em>- 3x⁵/x¹³ × 2x¹⁰y/15y² = -2x²/5y</em>
<em>11)</em>
<em>4xy¹¹/x⁷y⁶ × 6x⁸y/8x³ = 3y⁶/x</em>
<em>12)</em>
<em>y¹⁰/2x³ × 20x¹⁴/xy⁶ = 10x¹⁰y⁴</em>
<em>13)</em>
<em>5x⁻²/3x × 2y³/x¹⁰ = 10y³/3x¹³</em>
<em>14)</em>
<em>(5xy/8x⁻¹y²)² × 26y³/5x²y⁵ =</em>
<em>= 25x⁴/64y² × 26/5x²y²</em>
<em>= 65x²/32y⁴</em>

Answer:
55
Step-by-step explanation:
The inverse of this function is y =
You can find the inverse of any function by switching the x and y values. Once you've done that, you can solve for the new y. The result will be the inverse of the function. The work for this one is below.
y = ----> Switch the x and y
x = -----> Add 9 to both sides
x + 9 = ----> Take the natural log (ln) of both sides. This will case the e to cancel on the right side.
ln(x + 9) = 2y ----> Divide both sides by 2.
y =
This will be your inverse function.
Answer:
91
Step-by-step explanation:
25% of 73 = 18.25
18.25 + 73 = 91
actual answer = 91.25
