Answer:
The answers would be as follows:
3
3
1
1
Step-by-step explanation:
We can tell that the first two have an infinite number of solutions because when we try to solve, we get a true statement. The first one is done for you below.
-6x + 7 = -6x + 7 ------> Add 6x to both sides
7 = 7 (TRUE STATEMENT)
We can tell the next two have no solution due to the fact that they develop a false statement when trying to solve.
-3x + 7 = 3x + 7 ----> Subtract 7 from both sides
-3x = 3x ---> Divide by 3
-x = x (UNTRUE STATEMENT)
Answer:
he used 5 1/3 everything else is to low or high
Answer:
a) 98 degrees.
b) 8 degrees.
Step-by-step explanation:
supplementary angles: 2 angles that add up to 180 degrees.
a) to find the supplementary angle, all we have to do is:
180 - 82 = 98 degrees
Complementary angles: 2 angles that add up to 90 degrees.
b) to find the complementary angle, all we have to do is:
90 - 82 = 8 degrees
