Answer:

In one hour Stephanie earns $1.50 more than Marco

Step-by-step explanation:

w=9h

H is a variable

9×hour= wage

9×15= $135

9×18= $162

157.50-135=$22.50

189-162=$27

27-22.50=4.50

Now cause its per hour we know she earns $4.50 more in 3 hours.

4.50÷3=$1.50

Answer:

8 dimes and 14 quarters.

Step-by-step explanation:

d and q are the number of dimes and quarters, respectively.

"22 coins, all dimes and quarters"

d+q = 22

d = 22-q

"total value is $4.30"

0.10d + 0.25q = 4.30

substitution

0.10(22-q) + 0.25q = 4.30

2.2 + 0.15q = 4.30

q = 14

d = 22-q = 8

8 dimes and 14 quarters.

Answer:

You first plot the point (0,2), then when the x-value of the graph increases by 3, decrease the y-value of the graph by 1, and when the x-value o the graph decreases by 3, increase the y-value of the graph by 1.

Step-by-step explanation:

The equation would be [tex]y = -\frac{1}{3}x+2[/tex]. To graph it, you first need to find the y-intercept, which is the coordinate on the line when the x-value equals 0. If x = 0, [tex]y = -\frac{1}{3}x+2[/tex] would become [tex]y = 2[/tex] since anything multiplied by 0 would become 0. Now you've located the y-intercept, which is (0, 2). The slope of a line is the coefficient of the variable x. Since the slope is a negative number, the line will go downwards as it increases its x-value and goes upward as it decreases its x-value. A slope of [tex]-\frac{1}{3}[/tex] would mean that when the x-value increases by 3, the line's y-value will decrease by 1. And when the x-value decreases by 3, the line's y-value will increase by 1. An x-value increase of 6 would be a decrease of 2, and so on. Two other obvious points on the line would be (6,0) and (3, 1).

Answer:

b

Step-by-step explanation:

The correct number line should look like the one on the right in the image provided, with an open circle at 5 and the line shaded to the left of 5. Option B is correct.

A number line is defined as the number marked on the line calibrated into an equal number of units. For example -1, 0, 1, and so on.

Here,
To solve -5x + 10 > -15, we can start by subtracting 10 from both sides to get,

-5x > -25

Next, we can divide both sides by -5, remembering to flip the inequality sign because we're dividing by a negative number:

x < 5

This tells us that any number less than 5 will make the inequality true. So on the number line, we want to shade all the numbers to the left of 5.

The correct number line should look like the one on the right in the image provided, with an open circle at 5 and the line shaded to the left of 5. Option B is correct.

The cost of 40 pints of ice cream is given by the equation A = $ 96

Equations are mathematical statements with two algebraic expressions flanking the equals (=) sign on either side.

It demonstrates the equality of the relationship between the expressions printed on the left and right sides.

Coefficients, variables, operators, constants, terms, expressions, and the equal to sign are some of the components of an equation. The "=" sign and terms on both sides must always be present when writing an equation.

Given data ,

Let the cost of 40 pints of ice cream be A

Now , the equation will be

The cost of 6 pints of ice cream = $ 14.40

So , the cost of 1 pint of ice cream = cost of 6 pints of ice cream / 6

Substituting the values in the equation , we get

The cost of 1 pint of ice cream = 14.40 / 6

The cost of 1 pint of ice cream = $ 2.40

Now ,

The cost of 40 pints of ice cream A = 40 x cost of 1 pint of ice cream

Substituting the values in the equation , we get

The cost of 40 pints of ice cream A = 40 x 2.40

The cost of 40 pints of ice cream A = $ 96

Therefore , the value of A is $ 96

Hence , the cost is $ 96
