<h3>
<u>Explanation</u></h3>

- Solve the equation for d-term.
Because we cannot subtract or add up constants and variables, we simply move the same variable term to the same side and constant term to the same constant side.

Substitute d = -11 in the equation.

The equation is true for d = -11.

Answer:
5187
Step-by-step explanation:
At the end of 1 hour, the count is 2.5% greater than at the beginning.
5060 + 2.5% × 5060 = 5060 +126.5 = 5186.5
The count at the end of the hour was about 5187.
Answer:
1=n
Step-by-step explanation:
Step 1- Distribute into the parenthesis.
7(3)+5(3)n= 6n+1(6)+4(6)n
Step 2- Multiply
21+15n= 6n+6+24n
Step 3- Add common variables to simplify.
21+15n= (24n+6n)+6
21+15n= 30n+6
Step 4- Subtract the smallest variable to both sides.
21+15n= 30n+6
-15n -15n
21= 15n+6
Step 5- Subtract 6 to both sides.
21= 15n+6
-6 -6
15= 15n
Step 6- Divide both sides by 15.
<u>15</u>= <u>15n</u>
15 15
1=n
