-10x -120-11x
combine like terms so -10-11= -21x-120
Answer: 17.5
Step-by-step explanation:
7:10 = x:25
times both sides by 25
25(7/10) =x
than solve for x
X = 25 × (7/10)
X = 17.5
Answer:
D 28
Step-by-step explanation:
31 own 13-15
3 own 1-3
31 - 3 = 28
False because the left is statement in the right is reason
Answer:
x = -7
How to:
Rearrange the equation by subtracting what is to the right of the equal sign from both sides of the equation
5°x-(2°x-9)=0
Pull out like factors:
21 + 3x = 3 • (x + 7)
Equations which are never true: Solve 3 = 0
<em>Solving a Single Variable Equation:</em>
Solve : x+7 = 0
Subtract 7 from both sides of the equation : x = -7
