Answer:
C)
Step-by-step explanation:
16x - 7 = 11x - 32
16x - 11x = -32 + 7
5x = -25
x = -5
__________________________________________________
-4x - 10 = 2x + 20
-4x - 2x = 20 + 10
-6x = 30
x = -5
Answer:
x=9
Step-by-step explanation:
divide 4 from both sides to get x by itself. 4x÷4 = x, 36÷4=9 therefore x=9
DE/2 = 30.5
CE=30.5
DC=30.5
3x + 5 = 30.5
3x = 30.5 - 5
3x = 25.5
25.5/3 =8.5
x=8.5
Answer:
x+7 ≤ 20
Just take it step by step:
seven more than a number is a number plus 7 (x+7)- keep in mind we dont know what the number is so we use x to represent the number.
it then says it's equal to at most 20.
This means that it cant equal anything above 20 since 20 is the max. Therefore, it must be 20 and below that x+7 equals
x+7≤ 20
≤ -this symbol means less than or equal to
