Ok so you have to use PEMDAS . so first you have to get rid of the parenthesis.
2 x 6x = 12x then 2 x -5= -10
12 + 5x -8 = 12x -10
combine now: 12 - 8 = 4
5x + 4 = 12x - 10
- 4 -4
5x = 12x -14
-12x=-12x
-7x = -14
-14/-7
x=2
Answer:
x=2/5
Step-by-step explanation:
5x+6=8

Answer:
144
Step-by-step explanation:
Put the value where the variable is and do the arithmetic.
4(t -1)² = 4(7 -1)² = 4(6²) = 4(36) = 144
Answer:
The inequality is
88<x<93
Step-by-step explanation:
The average of Shondra's test scores in physics is between 88 and 93.
Let me give out the meaning of some inequality symbols
<= Less than or equal to
>= Greater than or equal to
< Less than
> Greater than
Let the average score be x
In this case , the average score is between 88 and 93
The inequality is
88<x<93
