Setting up a ratio
20 ft/7 ft
cannot be reduced ratio is the same as given
<u><em>Answer:</em></u>
x = -31.5
<u><em>Explanation:</em></u>
We are given that the quotient of x and -1.5 is 21
<u>This means that:</u>
![\frac{x}{-1.5} =21](https://tex.z-dn.net/?f=%5Cfrac%7Bx%7D%7B-1.5%7D%20%3D21)
To get the value of x, we will multiply both sides of the equation by -1.5
<u>This means that:</u>
![\frac{x}{-1.5} * -1.5=21*-1.5](https://tex.z-dn.net/?f=%5Cfrac%7Bx%7D%7B-1.5%7D%20%2A%20-1.5%3D21%2A-1.5)
x = -31.5
<u>Note that</u> the value of x must be negative because we are dividing by a negative number and the quotient is positive (-ve/-ve is +ve and +ve/-ve is -ve)
Hope this helps :)
Answer:
Write the mixed number as a decimal. 83/5
16.6
-8x/-8 - 8y/-8=0
x-8y/-8=0
x+y=0
the answer is x+y=0
