Equations for real
d + 9 = 25 (d= 6, 14, 16, 21)
d = 16
4 + 3 + 2 = 7 + 2
Addition Property of equality
25 + m = 49
m = 24
18x = 36
x = 2
Write an inequality: the distance, d, is at least 110 miles
d > or equal to 110
c - 8 = 25 (c=17, 28, 33, 35)
c=33
9 + 8 - 5 = 17 - 5
Subtraction Property of equality
t - 40 = 3
t = 43
w / 3 = 10
w = 30
The cost, c, is less than $45.
c < 45
x = 9
3 x 5 x 2 = 15 x 2
Multiplication Property of equality
12 = x - 11
x = 23
