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

Answer 1

Answer:

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

C) Erica bougth 2 movie tickets last month.

a rectangular playground is 40 meters by 10 meters. its area will be covered with shredded tires. each bag of shredded tires covers 200 square meters and costs $30. find the total cost for this project.

Answers

First, we need to find the area of the rectangular playground.
To do this, we must multiply 40 by 10.
We get 400 meters².
Now divide 400 by 200 and you get 2.
That means 2 bags will be needed to cover the entire area of the playground.
To find the price, multiply 30 by 2.
The total cost for this project will be $60.
Hope this helped you out! :)

−8x+3≥27 AND−13x+5≥57

Answers

Answer:

$x \leq -4$

Step-by-step explanation:

$-8x+3\geq 27 and -13x+5\geq 57$

LEts solve each inequality separately. then we find the intersection of both solutions.

$-8x+3\geq 27$

Subtract 3 on both sides

$-8x\geq 24$

Divide both sides by $-8$ , change the inequality symbol when we divide by negative number

$x \leq -3$

Now solve the other inequality

$-13x+5\geq 57$

Subtract 5 on both sides

$-13x\geq 52$

Now divide both sides by $-13$

$x \leq -4$

Now we take the intersection of $x \leq -3$ and $x \leq -4$

for $x \leq -3$ , we shade the number line to the left

$x \leq -4$ , shade the number line to the left

Intersection of both graph is $x \leq -4$

If m varies directly with x 2 , and m = 10 when x = −4, find the value of m when x = 3

Answers

If it is directly proportional, then:

m = kx
10 = k x -4
k = -2.5

m = 3 x -2.5
m= 7.5

For a set of 5 positive integers, the mean is 4, the mode is 1, and the median is 5. What are the 5 numbers?

Answers

Let the 5 integers be a,b,c,d and e (arranged in ascending order).
Since we know that the median is five, we can conclude that the value of c=5.
It's given that the mode is 1. 1<5, and has to be repeated more than once. Therefore, a and b = 1.
Now, the mean is 4. So, (1+1+5+d+e)=4
d+e=13 (d and e have to be greater than 5)
Which makes d=6 and e=7

In conclusion, the 5 integers are 1,1,5,6,7
