i need help with a math problem it says solve for t: -3(t - 2) + 7t=9t-9 can you show all the work please

Answers

Answer:

t = 3

Step-by-step explanation:

Given

- 3 (t - 2) + 7t = 9t - 9 ← distribute left side and simplify

- 3t + 6 + 7t = 9t - 9

4t + 6 = 9t - 9 ( subtract 9t from both sides )

- 5t + 6 = - 9 ( subtract 6 from both sides )

- 5t = - 15 ( divide both sides by - 5 )

t = 3

Answer:

t = 3.

Step-by-step explanation:

-3(t - 2) + 7t = 9t - 9 Distribute the -3 over the parentheses:

-3t + 6 + 7t = 9t - 9 Subtract 9t from both sides:

-3t - 9t + 7t + 6 = -9 Subtract 6 from both sides:

-3t - 9t + 7t = -9 - 6

-5t = -15

t = -15/-5

t = 3 (answer).

The students in Naomi's class sold calendars for a fund-raiser this year and last year. This year, the selling price of each calendar was 13.25. The price this year represents 6% more than the selling price of each calendar last year. What was the selling price of each calendar last year ?

Answers

We'll use the variable x to represent last year's price. First, we have to set up an equation:
$.06x+x=13.25$
We get this equation because $13.25 is 6% MORE than last year's price, meaning we need to add the original price to the increase. Next, we combine like terms and solve for x:
$.06x+x=13.25 \n 1.06x=13.25 \n (1.06x)/(1.06) = (13.25)/(1.06) \n x= 12.50$

Last year's price was $12.50.

Hope this helps!
