Make a proportion the sales tax is a percent of the total purchase and you just have to figure that out. 1,200/100=72/x solving this i get 6% sales tax using that. I find the rest by taking 6% of 2500 =150. And for part b make another proprtion x/100=108/6. And i get 1800 dollars
2^2 - 5t + 12 = 0
4 - 5t + 12 = 0
-5t + 16 = 0
-5t = -16
t = 16/5
Answer: 16/5 in fraction form or 3.2 in decimal form
Answer: 7 inches
Step-by-step explanation:
If x is the first piece, and the second piece is twice as long, then the second piece is 2x.
If the third piece is three times as long as the first piece, x, then the third piece is 3x.
The 42-inch board must be equal to all 3 pieces, so we will set up an equation and solve for x.
42 = x + 2x + 3x
42 = 6x
42 = 6x
7 = x
The first piece is 7 inches long.
