<span>Equivalent fractions are numbers with the same value for a number.
Multiply the numerator as well as the denominator by the same number. Therefore its like multiplying by 1.
45/60
3/4 = 9/12
<u>45 </u>x <u>15
</u>60 15 = 3/4
<u>45</u> x <u>5
</u>60 5 = 9/12

<span>5x-0.1=4x
Subtract 5x from both sides so that the x variable is only on one side
-0.1=-x
Divide both sides by -1 to get rid of the negative on the side with the x variable
Final Answer: 0.1=x</span>
Answer:
Whatever you do to one side you must do it to the other side of the equation.

Answer:
Step-by-step explanation:
16x⁸ - 81y⁸ is the difference of squares.
16x⁸ - 81y⁸ = (4x⁴)² - (9y⁴)² = (4x⁴ + 9y⁴)(4x⁴ - 9y⁴)
Note that 4x⁴ - 9y⁴ is also the difference of squares.
4x⁴ - 9y⁴ = (2x²) - (3y²)² = (2x² + 3y²)(2x² - 3y²)
16x⁸ - 81y⁸ = (4x⁴ + 9y⁴)(2x² + 3y²)(2x² - 3y²)
The volume of a cube is the side legnth cubed
V=s^3
27=volume
27=s^3
cube root both sides
3=s
the side legnth is 3m
