Define the variables: a is the number of apples I can buy g is the number of grapefruits I can buy.
Write the equation: 15 = 0.50a + 2g
The radius is 4.
Find the radius of the circle whose equation is (x + 5)2 + (y + 8)2 = 16
Answer:
-13x + 14
Step-by-step explanation:
Many of the terms cancel out (ex: + 7x and -7x, -2x and +2x)
So, with those omitted, you are left with:
-13x + 14
First the left side of an equation:"six added to twice the sum of a number and four": ( x - a number )
6 + 2 ( x + 4 )Then the right side:"one half of a difference of three and a number":1/2 ( 3 - x )And the solution:A ) 6 + 2 ( x + 4 ) = 1/2 ( 3 - x )
