Answer:25x=320=12.8
Step-by-step explanation:
a number=x
x*25=25x
25x=320
320/25=12.8
x=12.8

Answer:
J = 7.5
Step-by-step explanation:
* This is going off of the estimate that the = sign means the equation is = to 0, as there is no value after the equal sign. *
First, start off by adding all of the like numbers.
11 + (-3) + 7 = 8 + 7 = 15
- 1/8 j - 3/8 j = - 4/8 j.
Combining those two sums, we get:
15 - 4/8 j = 0
Subtract 15 from both sides,
-4/8 j = -15
Simplify -4/8 to -1/2, and then to -0.5
-0.5j = -15
Divide.
-15/-0.5 = 7.5
When you divide a negative number by another negative number, you get a positive. Therefore, the answer is J = 7.5
If the number after the = sign IS NOT 0, then when you get to 15 - 0.5j, just do the steps but with a number that isn't 0.
