Answer:
a. False. A constant is a number on it's own, and 5 would be the coefficient of x. 8 would be the constant.
b. False. -6.5 would be the constant, since it's on its own. But actually, x would be carrying on a coefficient of 1. Letters are variables, not constants.
c. True.
Answer:
No
Step-by-step explanation:
90/(-9) = -10. Any time we multiply or divide with one of the numbers being negative means that the solution will be negative. If both numbers are negative the answer will be positive. Hope this helps:)
Answer:
V=35
Step-by-step explanation:
Start by multiplying by 7 on both sides:
V=35
Nikita's value is 4 times less than Bettina's value. I believe this is the answer.
To do this, we must allow this hidden number to be x.
2x + 4 = 8
Now we will solve by first subtracting 4 from each side:
2x = 4
Now we will divide each side by 2 to isolate the variable:
x = 2
Therefore, the mystery number is 2.
