You bought 4 pizzas and paid $7.00 each and cut the pizza into 8 equal slices. You
then sell the slices for $1.75 each. How many pieces would you have to sell to to pay
for the original cost of the 4 pizzas?

Answers

Answer:

You would have to sell

16 slices to pay for the

original price of the 4

pizzas

Step-by-step explanation:

$7.00 a box so you would have to multiply to get to

full price. $7.00x4=$28.00 The full price is $28.00.

If you are selling the slices for $1.75 each you would

also have to divide to know how many slices to sell

to get back to $28.00. 28.00÷1.75=16. So you would

have to sell 16 slices to get back to the full price.

Hope this helps.

3x + 10+ 2x =50 isks

Answers

Answer:

x = 8

Step-by-step explanation:

3x + 10+ 2x =50

5x = 50 - 10

x = 40/5

x = 8

The value of x would be equal to 8.

We know that equation is an expression that shows the relationship between two or more numbers, variables, and a mathematical equation is a statement with two equal sides and an equal sign in between.

We are given the equation as;

3x + 10+ 2x =50

Now solve for x;

3x + 10+ 2x =50

Combine like terms;

5x = 50 - 10

x = 40/5

x = 8

The solution will be 8.

Step-by-step explanation:

We have the equation:

Since their bases are the same, the exponents must be equivalent. So:

[tex]-3r=2r+3[/tex]

Solve for r, subtract 2r from both sides:

profit per shirt sold
shirts: 5 10 15
profit: $7.50 $15.00 22.50

Answers

Answer: 1.5

Step-by-step explanation:

7.50/5 = 1.5

15/10 = 1.5

22.50/15 = 1.5

Answer:

$1.50

Step-by-step explanation:

To find the unit rate, we can divide the number of shirts to the profit that was made to find the unit cost per shirt.

7.50 / 5 = $1.50

15 / 10 = $1.50

22.50 / 15 = $1.50

Answer: there are really too many options...

Step-by-step explanation:

If you just want to keep it in simplest fraction form, the negatives cancel, giving you 8/3

But if you want to make it a mixed number, the negatives still cancel and since three goes into eight twice, with two leftover, you get 2 2/3

But if you want to make it a decimal, eight divided by three gives you 2.6666 repeating

Write the equation of a line that passes through the points (−3, 7) and (3, 3)
y=−2/3x+5

y=2/3x+1

y=−2/3x+9

y=2/3x+9

Answers

Step-by-step explanation:

You can write an equation of a line conveniently by point-slope form. It's in the form of [tex]y -a = m(x -b)[/tex] where [tex](b,a)[/tex] is the coordinates of a point that's on the line and [tex]m[/tex] is the slope of the line.

Now choose a point (It doesn't really matter which one) and plug that in the equation. I'll choose [tex](-3,7)[/tex] where [tex]a = 7[/tex] and [tex]b = -3[/tex]

[tex]y -a = m(x -b) \\ y -7 = m(x -(-3)) \\ y -7 = m(x +3)[/tex]

The next thing we have to do now is finding the slope, [tex]m[/tex], where it's equal to [tex]\frac{y_{2} -y_{1}}{x_{2} -x_{1}}\\[/tex]. I'll make [tex](-3,7)[/tex] point 1 and [tex](3,3)[/tex] point 2.

[tex]m = \frac{3 - 7}{3 -(-3)} \\ m = \frac{3 - 7}{3 +3} \\ m = \frac{-4}{6} \\ m = -\frac{2}{3}[/tex]

Now let's plug that to our equation.

[tex]y -7 = m(x +3) \\ y -7 = -\frac{2}{3}(x +3)[/tex]

Now we have the equation but out of all the choices it seemed that all of them are in slope-intercept form all you have to do now is make our equation rewrite it in slope-intercept form.

[tex]y -7 = -\frac{2}{3}(x +3)\\ y -7 = -\frac{2}{3}x -\frac{2}{3}(3) \\ y - 7 = -\frac{2}{3}x -2\\ y = -\frac{2}{3}x +5[/tex]

Answer:

[tex]y = -\frac{2}{3}x +5\\[/tex] is your equation.

What is Theorem?

A mathematical proposition or assertion that has been proven to be true is known as a theorem.

According to this theorem, when two straight lines cross, they create two sets of linear pairs with matching angles. The adjacent angles created by the junction of these two lines are likewise said to be supplementary, or equivalent to 180 degrees.

It is given that,

∠2=∠4

From the diagram, it is observed that two straight lines cross, and they create two sets of linear pairs with matching angles as a result of the Vertical Angles Theorem angle 2 is congruent to angle 4.

Thus, the statement “Angle 2 is congruent to angle 4" is justified by the Vertical Angles Theorem. Option C is correct.
