equivalent
10t < 140
t < 14
5t + 40 > 500
t > 92
What is the value of x?
2x=10
x=5
Divide both sides by 2

x > 14
20x=400
x=20
Divide both sides by 20

expression
m - .3 > 1.45
m > 1.75
2d +20 < 120
d < 50
Find value of x
5x+40=90
x=10
5x=50
Divide both sides by 5

equivalent, inequality, expression, solution of inequality, complementary angles, supplementary angles
inequality
1/2 x < 6
x < 12
1/2 x - 10 > 22
x > 64
4x + 5x + 3 =84
x=9
9x+3=84
9x=81
Divide both sides by 9
Fill in the blank
Be ______
Mine
Two angles whose measure add to 90 degrees
equivalent, inequality, expression, solution of inequality, complementary angles, supplementary angles
Complementary Angles
-2/3 a > 6
a < -9
-3b -2 < 13
b > -5
x/2 + 3=9
x=12
x/2=6
Multiply both sides by reciprocal (multiply by 2)
