Answer:

x = .98

Step-by-step explanation:

-.5(17x - 24) = 3.4x - 6 + 6.3x

-18.2x = -18

18.2x = 18

x = .98

Erica earns a rebate each month on her meals and movie tickets. She earns $3 for each movie ticket and $0.80 for each meal. Last month Erica purchased 15 meals and earned $18.Part A: Create an equation that will determine the number of movie tickets she purchased. (3 points)

Part B: Solve this equation justifying each step with an algebraic property of equality. (6 points)

Part C: How many movie tickets did Erica purchase last month?

Answers

A) Let t represent the number of tickets Erica bought. The the equation describing her rebates can be written as

... 3t + 0.80×15 = 18

B) Here's the solution to the equation.

... 3t + 12 = 18 . . . . . . simplify; rules of arithmetic

... 3t = 6 . . . . . . . . . . .subtract 12; subtraction property of equality

... t = 2 . . . . . . . . . . . . divde by 3; division property of equality

Write the ratio in three different formats: In a year, there are 4 months that have 30 days. Write a ratio of the months with 30 days to the months with other than 30 days. A.1 to 3, 1:3, 1/3B.1 to 2, 1 :2, 1/2C.2 to 1, 2:1, 2/1
D.3 to 1, 3:1, 3/1

Answers

This problem is an example of ratio and proportion. A ratio is a comparison between two different things. You are given 4 months that have 30 days. You are required to get the ratio of the months with 30 days to the remaining months that have a different number of days. First, you will get the ratio as 4/30 = 2/15. Assuming that the other months also has 30 days. Then the second ratio is 8/30 = 4/15. Multiply 2/15 to 15/4 you will get ½. Other forms of this is 1:2 or 1 is to 2. The answer is B.

so find the amount of months that don't haave 30 days
12 months total
4 have 30 days
12-4=8
so the ratio of months that have 30 days to the months that do not havve 30 days is 4 to 8 or 4:8
this can be simplified like a fraction
4:8 4/8=1/2
ratio is
1 to 2, 1:2, 1/2

answer is B
