Be prepared to show me your line! :)
Use the addition principle to this equation and then find the solution.
5y - 7 = 13
Add the opposite to cancel out
5y = 20
y = 4
4x = -96
X = -24
Adding Integers
(PEMDAS)
(6 + -4) + 7=
9
2). Ella's average score after four tests was 88. What score must Ella average on the next 2 tests to have a 6-test average of 90? YOU GOT THIS ELLA! :P
94
Equivalent Equations
5x - 3x = 4 + 10
2x = 14
x=7
Use the addition principle and then find the solution
3x = 11x + 24
-8x = 24
x = - 3
22). m + 8.7=10.25

Subtracting Integers
10 - 3 - 6 - 5 =
10 + - 3 + -6 + -5 = -4
DOUBLE Jeopardy!!!
How many children does Mrs. Sharp have?
For an extra $1000-name them!
Simplify the equation by combining like terms then find the solution
-4x = 19 + 9
- 4 x = 28
x = -7
(-10)-(-8)-(+6)
-8
(+10)+(-20)-(-30)

( 3 - 5 ) X ( 6 - 10)=
(3 + -5) = -2
(6 + -10) = -4
-2 + -4 = -6
5) The diameter of a nickel is 21 mm. Find the circumference of the nickel to the nearest millimeter.
