Answer:
Step-by-step explanation:
The question is 10b/(2b + 8)
The reciprocal will not make a minus sign. B and C are both wrong. Powers can create a minus sign but not this kind of question
Two terms creating a binomial must stay together. In this case (2b + 8) must be entirely in the top or bottom of the fraction. That makes D wrong.
Answer: A is the correct reciprocal.
Answer:
3x + (-2) = 2x + 4
Step-by-step explanation:
Look at the first part. There are three boxes with "x" in them and 2 boxes with "-1" in them.
Since there are three boxes with "x", that means that the first number in the equation will be 3x, making A and B incorrect answers.
Now look at the two "-1" boxes. If the answer was C, then the boxes would be yellow and have 1 on it like the ones on the right, making C an incorrect answer.
This leaves you with D, or 3x + (-2) = 2x + 4
Hope this helped!
Answer:
Here is the answer and explain it step by step
Step-by-step explanation:
Answer:
x=30
Step-by-step explanation:
Find the value of x that will make A and B parallel
For A & B to be parallel, the interior angles must be supplementary, i.e.
4x+2x = 180
6x=180
x=30
When x=30, the interior angles are 120 and 60 which are supplementary.
