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.

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

Answer:

10/3 minutes

Step-by-step explanation:

12 minutes to run 6 times is the same as 2 minutes to run once (ratios)

so it takes 2 minutes to run once around a 600 m track

so 2 minutes/600m = x minutes/1000m

x = 2/600 * 1000 = 20/6 = 10/3

Answer:

10/3

Answer:

Proportional

Step-by-step explanation:

It is proportional because the relationship between the quantities are constant. If we look at the first two points, 10-5 / 2-1. = 5       If we look at other points, they will all equal 5. This means it is constant and therefore proportional.

Answer:

k < -90

Step-by-step explanation:

The required probability of not stamp not along an outer edge is 8/25.

A fraction is a numeral that represents a rational number.

Let a and b be two numbers, then their fraction can be represented as a/b.

Given that,

Total numbers of stamp in a stamp sheet of 10 by 10 = 100,

On one edge there would be 10 stamps but on each diagonal there will be 1 stamp common,

Therefore, total number of stamps  on outer edge will be = 9 x 4 = 36

Remaining stamps = 100 - 36 = 64

The fraction value of 64 out of 100 = 64 / 100 = 8 / 25

The required fraction value of stamps is 8 / 25.

Answer:

The constant of proportionality is 2.5. This can be expressed as (cups of sugar) * 2.5 = cups of flour

Step-by-step explanation:

The constant of proportionality is y/x. Since flour comes second, we'll plug flour in for y here.

5/2 = 2.5

15/6 = 2.5

20/8 = 2.5

The constant of proportionality is 2.5. This can be expressed as (cups of sugar) * 2.5 = cups of flour

Answer:60

Step-by-step explanation:

Answer:

5(x – 4) + 3x – 9x = 6 – (2x + 5) + 8x

step1:-   5x - 20 + 3x - 9x = 6 - 2x - 5 + 8x

step2:- 5x + 3x - 9x - 20 = 8x - 2x + 6 - 5

-x - 20 = 6x + 1

-20 = 7x + 1

step 4

-21 = 7x

divide both sides by 7:-

Answer:

A. (5x - 2) - (2x +1)

B.  x -1

C. 68

Step-by-step explanation:

Heather = 5 times Donna -2   H = 5D - 2

Gina = 2 times  Donna + 1    G = 2D + 1

Plug in D for X and you get

H = 5x -2

G = 2x + 1

If Heather's expression is 5x -2 and Gina's expression is 2x + 1 then to show how many more Heather has than Gina. You have to subtract Gina from Heather.

(5x - 2) - (2x +1)

Now to simplify it, you just combine all the like terms.

5x - 2 - 2x -1 = 3x - 3   and then you can simply this further by dividing all terms by 3.    x - 1

To solve how many Heather has if Donna has 14. You substitute 14 for x in Heather's equation.    5 (14) -2  =  70 - 2 = 68

The required cost of each bottle is $0.4.

Grayson bought snacks for his team's practice. He bought a bag of apples for $2.62 and a 15-pack of juice bottles. The total cost before tax was $8.62, and how much each bottle of juice is to be determined.

In mathematics, it deals with numbers of operations according to the statements. There are four major arithmetic operators, addition, subtraction, multiplication, and division,

Here,
let the cost of the bottle be x,
According to the question,
2.62 + x*15 = 8.62
x = 8.62 - 2.62 / 15
x = 6 / 15
x = 0.4

Thus, the required cost of each bottle is $0.4.
