Answer: x = -2
<u>Step-by-step explanation:</u>
vertical line means it will be x = ___
Set the x-values equal to each other and solve for x.
3 - 2x = x + 9
<u> +2x</u> <u>+2x </u>
3 = 3x + 9
<u>-9 </u> <u> -9 </u>
-6 =3x

-2 = x
Given problem;
A = 4 π R²
To solve for R, we have to make it the subject of the expression.
Since
A = 4 π R² , follow these steps to find R;
Multiply both sides by
A x
=
x 4 π R²
= R²
Then find the square root of both sides
√R² =
R = 
The solution is 
X= 1st integer
x+2= 2nd integer
x+4= 3rd integer
Add the integers together
x + (x + 2) + (x + 4)= 279
combine like terms
3x + 6= 279
subtract 6 from both sides
3x= 273
divide both sides by 3
x= 91 first integer
Substitute x=91 to find 2nd & 3rd integers
2nd Integer
=x+2
=91+2
=93
3rd Integer
=x+4
=91+4
=95
ANSWER: The three test scores are 91, 93 and 95.
