Michelle plans on raising $80 for her softball team. To raise the money, she is selling team shirts for $10 each.
So far she has raised $20. To calculate how many more shirts she needs to sell, Michelle subtracts 20 from 80
and then divides by 10.
Which of the equations below can be solved using the same steps?
A. 10x + 20 = 80
B. 20x + 10 = 80
C. 80x - 20x = 10
D. 10x + 20x = 80

Answers

Given:

Michelle plans on raising $80.

Selling price of each shirt = $10

So far she has raised $20.

To find:

The number of more shirts she needs to sell.

Solution:

Let x be the number of more shirts she needs to sell.

Selling price of one shirt = $10

Selling price of x shirt = $10x

Total raising amount = $(10x + 20)

Michelle plans on raising $80. So,

[tex]10x+20=80[/tex]

Subtract both sides by 20.

[tex]10x=80-20[/tex]

[tex]10x=60[/tex]

Divide both sides by 10.

[tex]x=\dfrac{60}{10}[/tex]

[tex]x=6[/tex]

So, the required equation is [tex]10x+20=80[/tex]

Therefore, the correct option is A.

Answers

Answer:

The answer is 267.

Step-by-step explanation:

If we wanted to represent this scenario as an equation, it would be 22.40-14+.5x (x being the amount of texts after 250). We are using PEMDAS, but because the variable is unknown, we skip multiplication and just go left to right. 22.40 - 14 = 8.40. With 8.40, we now know how much it costed AFTER 250 messages (how much she owes after $14). If we want to find how many PER 50 cents, we have to DIVIDE (reverse of multiplication). 8.4 / .5 = 16.80. Because you can't send .8 of a text message, you round to get 17. 250 + 17 = 267 (messages sent that month).

Therefore the answer is 267 (250 + 17)

Solve the proportion 2/7=c/28
Hurry!!!

Answers

Answer:

C = 8

Step-by-step explanation:

2/7 = c/28

Multiply to get c by itself

2/7 x 28 = c

Solve

2/7 x 28 = 8

C = 8

The value of c is 8 in the proportion 2/7=c/28.

What is Equation?

Two or more expressions with an Equal sign is called as Equation.

The given proportion is  2/7=c/28

Two divided by seven equal to c divided by twenty eight.

We have to find the value of c.

We find the value of c by applying cross multiplication

28×2=7c

56=7c

Divide both sides by 7

56/7=c

Divide numerator and denominator by 7

We get c=8

Hence, the value of c is 8 in the proportion 2/7=c/28.

Values of q are factors of
.

Answers

Answer:

-4, 3

The answer to the next question is: A (+4/3), B (+2/3), D (+2), E (+4), G (+1/3), H (+1)

Step-by-step explanation:

For edge:)

Rational root theorem is used to determine the potential roots of a function

The potential roots are: [tex]\mathbf{ \pm 1, \pm 2, \pm 4, \pm \frac{1}{3} ,\pm \frac{2}{3}, \frac{4}{3}}[/tex]

The function is given as:

[tex]\mathbf{f(x) = 3x^2 - x - 4}[/tex]

p represents the leading coefficient, while q represents the constant term.

So, we have:

[tex]\mathbf{p = 3}[/tex]

[tex]\mathbf{q = 4}[/tex]

The factors of p and q, are:

[tex]\mathbf{p =\pm 1, \pm 3}[/tex]

[tex]\mathbf{q =\pm 1, \pm 2, \pm 4}[/tex]

So, the potential roots are:

[tex]\mathbf{Roots = \pm\frac{q}{p}}[/tex]

[tex]\mathbf{Roots = \pm\frac{\pm 1, \pm 2, \pm 4}{\pm 1, \pm 3}}[/tex]

So, we have:

[tex]\mathbf{Roots = \pm 1, \pm 2, \pm 4, \pm \frac{1}{3} ,\pm \frac{2}{3}, \frac{4}{3}}[/tex]

Hence, the potential roots are: [tex]\mathbf{ \pm 1, \pm 2, \pm 4, \pm \frac{1}{3} ,\pm \frac{2}{3}, \frac{4}{3}}[/tex]

Paola and Tom opened a lemonade stand. This week they sold 20 cups of lemonade and received $5 in tips. If they spend $30 on supplies, which inequality could be used to find x, the price of each cup they must sell to make a profit?

Answers

Answer:

20x + 5 < 30

Step-by-step explanation:

To make a profit, the price on supplies must be less than the amount at which they sold their wares

Since they received $5 in tip, the amount of profit left to be accounted for is 30-5 = 25

So now, we need the smallest price at which they will sell per lemonade to make a profit

Mathematically, that will be;

20x + 5 > 30

Using this inequality X they will know the value of x that will give them profit

Answer:

We have to multiply 4 with 3 to make it equal to 12.

Step-by-step explanation:

Given the two equations:

[tex]6x - 5y = 21\\ 4x + 7y = 15[/tex]

In elimination method for solving two linear equations in two variables, one variable is eliminated by making the coefficients of the variable equal to each other and then the equations are subtracted from each other so that only one variable remains.

Here, we have to eliminate [tex]x[/tex].

The coefficients are 6 and 4.

The least common multiple of 6 and 4 is 12.

Each horse needs 300 milligrams and each horse eats 15 pounds of feed per day.

This means that 300 milligrams should be in 15 pounds of feed.

In 2,000 pounds therefore, the medication that should be added is;

= (2,000 * 300) / 15

= 40,000 milligrams of supplement

Chelsea is budgeting for her trip to the mall. She
does not want to spend any more than $140. If
she wants to buy a dress that costs $28.50 and
I some shirts that cost $20.75 each, how many
shirts can she buy? Use the inequality to help
solve the problem.
140 > 28.50 + 20.75x

Answers

Answer:

Chelsea can buy 5 shirts.

Step-by-step explanation:

Subtract 28.50 from 140. This is because subtraction is the inverse of addition, so it will cancel out. 111.50 > 20.75xDivide both sides by 20.75. Division is the inverse of multiplication. 5.3734939759 > x

You can't split shirts when buying them, so Chelsea can buy 5 shirts.

f(x) = -5.4x+12.6

What is the y intercept of the graph of this function ?​

Answers

Answer:

Step-by-step explanation:

The y intercept means that x=0, therefore you will plug in 0 in your equation.

f(x) = -5.4x + 12.6

f(0) = -5.4(0) + 12.6

f(0) = 0 + 12.6
