Answer:
Step-by-step explanation:
For the second column
1. 4*5+8=28
2. 4*5.5+8=30
3. 4*6+8=28
4. 4*6.5+8=34
5. 4*7+8= 36
6. 4*7.5+8=38
For the third column
1. 7*5-11=24
2. 7*5.5-11=27.5
3. 7*6-11=31
4. 7*6.5-11=34.5
5. 7*7-11=38
6. 7*7.5-11=41.5
Answer:
j = -10
Step-by-step explanation:
Given the mathematical expression;
-10 − 10j = -9j
To find the value of j?
Rearranging the equation, we have;
-10 = -9j + 10j
-10 = j
Therefore, j = -10
Answer:
x = 120
Step-by-step explanation:
Since they are supplementary, they add up to 180 degrees.
So, you can say x + x/2 = 180
Then, you would solve it like an algebra problem.
Multiply both sides by 2
2x + x = 360
Simplify
3x = 360
Divide both sides by 3
x = 120
