Simplify 15y^-7/18y^-3 Assume y≠0

weeeeeb [17]

The first step for simplifying the above fraction is to divide the terms with the same base by subtracting their exponents.
$\frac{15}{18y^{-3-(-7)} }$
Remember that when there is a "-" sign in front of the parenthesis,, we need to change the sign of each term in the parenthesis. This changes the fraction to the following:
$\frac{15}{18y^{-3+7 } }$
Calculate the sum of the exponents.
$\frac{15}{18 y^{4} }$
Lastly,, reduce the fraction with 3 to find your final answer.
$\frac{5}{6 y^{4} }$
Let me know if you have any further questions.

pochemuha

Answer:

2 cups of clay

Step-by-step explanation:

Given data

we are given that 6 cups of water for every 12 cups of clay

i.e

12 cups of clay require 6 cups of water

4 cups of clay will require x cups of water

cross multiply

12x= 4*6

12x= 24

divide both sides by 12

x= 24/12

x= 2cups

Hence 4 cups of water will require 2 cups of clay

Solve for x. 1/2x + 3 = 2/3x + 1

makvit [3.9K]

Answer:

x = 12

Step-by-step explanation:

$\frac{1}{2}$ x + 3 = $\frac{2}{3}$ x + 1

multiply through by 6 ( the LCM of 2 and 3 ) to clear the fractions

3x + 18 = 4x + 6 ( subtract 3x from both sides )

18 = x + 6 ( subtract 6 from both sides )

12 = x
