Answer:
Change in temperature was 12 degrees
Step-by-step explanation:
If you start with five degrees and end into negative 7 degrees, you can find the result within two steps
5 degrees minus 5 = 0 degrees
then, 0 degrees minus 7 = -7 degrees
Because you subtracted 5 from five, and 7 from seven, you add those two values together
7 + 5 = 12 degrees
So the change in temperature was 12 degrees

Answer:
B) 120
Step-by-step explanation:
Initial problem: 90/x = 3/4
Cross multiply to get:
90*4 = 3x
360 = 3x
x = 120
Check (optional):
90/120 = 3/4
(simplify):
3/4 = 3/4 so it is correct

Answer:
circle of diagram (89).&"71
Answer:
(3, 1)
Explanation:
because that's where they intercept
The value of x after solution of the equation 8x = -16 is -2 and it is not possible to solve this equation using multiplication.
According to the question,
We have the following equation:
8x = -16
Now, this equation can not be solved using multiplication because 8 is already in multiplication with x on the left hand side. If 8 would have been in division then it could be solved using multiplication.
So, dividing by 8 on both the sides:
x = -16/8
x = -2
Hence, the value of x after solution of the equation 8x = -16 is -2 and it is not possible to solve this equation using multiplication.
