One the temp is going dropping which sets up for a negative number resulting in -3 degrees
9 x 9 = 81
81 - 21 = 60
60 / -6
10
Answer:
The solution for x would be 4.
Step-by-step explanation:
2x - 1 = 7
The value of x is unknown, but you do know that you are multiplying 2 by x. So, if you rewrite the equation as 7+1=2x, you know that 8=2x. If you then divide both sides by 2, you're left with 4=x which would mean that the variable x has a solution of 4
No as complementary angles add up to whisk 180 degrees, however supplementary angle would be true for this question
