Step-by-step explanation:
PART C; The original price of Rylee’s groceries was $23.50. This money is leaving her bank account, so represent the amount with a negative sign:
-$23.50.
Rylee got a 20% discount on her purchase. In other words, she got 20% of her money back. The expression that represents the net change in her bank account is
-$23.50 – (-$23.50 × 0.2).
Further simplify the expression by factoring -$23.50 from both terms:
-$23.50 – (-$23.50 × 0.2)
=
-$23.50(1 – 0.2)
=
-$23.50(0.8).
The net change to her banking account balance is $83.22.
What is net change?The net change theorem states that when a quantity changes, the final value equals the initial value plus the integral of the rate of change. Net change can be a positive number, a negative number, or zero.
Given that, She spent $36.50 plus 8% tax. (to calculate the tax amount, we have to multiply the cost by the percentage in decimal form)
36.50 x (8/100) =$2.92 (value of tax)
Adding to the original cost
36.50+2.92 = $39.42
Then, she spent $25 to refuel her car at the gas station.
39.42 +25 = $64.42
She bought groceries worth $23.50. At the grocery checkout, she handed over a coupon for a 20% discount on her purchase
23.50 x (20/100) = 4.7 (amount of discount)
Subtracting to the purchase
23.50 -4.7= $18.8
Hence, adding to the total cost.
64.42 +18.8 = $83.22

rewrite [tex]-2x+3y=-15[/tex] in slope-intercept form
Answer: [tex]Y = \frac{2}{3} x - 5[/tex]
Step-by-step explanation:
Answer: y=7.5+-5
Step-by-step explanation:
Divide 3y from itself and -15 to cancel out the Y variable. So Y is equal to -5. Then you would be left with -2x=-15. So then you would have to divide -2x from itself and -15, which would give you 7.5, and that is your x variable.

Find the surface area of this net.
_______ square centimeters
Answer:
228
Step-by-step explanation:
First, let's find the area of A and C
5 ✕ 12 = 60
60 ✕ 2 = 120
Then B
8 ✕ 12 = 96
Then the triangles
3 ✕ 5 ÷ 2 = 12 / 2
But now think,because there are 2 triangles, so we have to times it by 2 later so we can just leave it like this.
120 + 96 + 12 = 228
Jason loves to play the piano but doesn't like practicing the exercises his piano teacher assigns. Jason knows the exercises will help him play better though, so he tries to motivate himself using his favorite treat — chocolate chip cookies. Jason gives himself 5 cookies for every hour he practices.
There is a proportional relationship between the amount of time (in hours) that Jason practices the piano, x, and how many cookies he gives himself, y.
Graph this relationship. Select two points to draw a line.

describe how you can tell wether a lines slope is greater than 1 equal to 1 or less than 1 pls help ill give you brainliest
Answer:
the slope is determined by rise over run, meaning you first have to see if the line is negative or positive by the direction it is facing, then you have two points that match accordingly to rise over run, to find out you have to see how many boxes(y) you are rising and however many boxes to the right(x) you are running, then you divide rise/run
