Answer:
x = -3
Step-by-step explanation:
12 - 4x-5x = 39
Combine like terms
12 - 9x = 39
subtract 12 from each side
12 -9x-12 = 39-12
-9x = 27
Divide by -9
-9x/-9 = 27/-9
x = -3
There is three terms in the expression "n2+6n-3".
In Algebra a term is either a single number or variable, or numbers and variables multiplied together. Terms are separated by + or − signs, or sometimes by divide.

Answer:
The rates are 1/2 yards per hour
Step-by-step explanation:
Here, we want to calculate the rate of change in the amount of yarn
We start by calculating the difference between what we had initially and what we have now
That will be;
3 3/4 - 1 1/8
= 15/4 - 9/8 = 21/8 yards
So we now divide this by the number of hours
21/8 yards divided by 51/4
= 21/8 * 4/21 = 1/2 yards per hour
