Answer:
(7) The value of -j is 9.
(8) The value of -(-j) is -9.
(9) The value of (-j)(-j) is 81.
Step-by-step explanation :
<u>Part 7:</u>
Given algebraic expression is:
j = -9
Now we have to determine the value of (-j).
-j = - (-9) = 9
The value of -j is 9.
<u>Part 8:</u>
Given algebraic expression is:
j = -9
Now we have to determine the value of -(-j).
- (-j) = - [-(-9)] = -9
The value of -(-j) is -9.
<u>Part 9:</u>
Given algebraic expression is:
j = -9
Now we have to determine the value of (-j)(-j).
(-j)(-j) = [- (-9)] × [- (-9)] = 9 × 9 = 81
The value of (-j)(-j) is 81.

Divide 3 by 8 (the fraction): 3/8=.375. Make into a percent: 37.5% or 38% (depending on what your teacher wants) and that's your answer :)
Answer:
x = 6
Step-by-step explanation:
We want to solve:
First, isolate the variable by moving all the terms with x to one side and all the constants to the other side:
Combining the fraction on the left, we get:
6/3 = 2, so:
2x = 12
Dividing both sides by 2 yields:
x = 6
to find a percent you have to find a equivalent fraction that equals to ___\100
