7x-3= -24 what is x and how do you find it?

Answers

Answer 1

Answer:

x = -3

Step-by-step explanation:

7x - 3 = -24 (Given)

7x - 3 + 3 = -24 + 3 (Added 3 on both sides by using the addition property of equality)

7x = -21 (Simplified)

7x/7 = -21/7 (Divided 7 on both sides by using the division property of equality)

x = -3 (Simplified)

Therefore, x = -3.

Answer 2

Answer:

x= -3

Step-by-step explanation:

You do the opposite.

So,

-24 +3

= -21

-21/ 7

= -3

Therefore, the answer is -3

Step-by-step explanation:

A wedding reception was
being held at Stefano's
restaurant. They charged
$2.00 per person for
appetizers, $20.00 per
person for the main course
and $250 for the wedding
cake. There were 50 people
at the reception. What was
the total cost of the
reception?

Answers

Answer:

the total cost of the wedding would be: 1,350

Step-by-step explanation:

2×50=100 and 20×50=1,000

100+1,000=1,100

1,100+ 250= 1,350

total for wedding is 1,350

:)

Answer: The answer for this problem is $1350.

Step-by-step explanation:

The first thing you do is to see how much money for the appetizers and the main course did all 50 people pay.

50 x 2 = 100, how much money in total for the appetizers

50 x 20 = 1000, how much money in total for the main course

Once you're done with that! Next, you add the total prices for the appetizers and the wedding cake. Then, you add up the $250, so you get your answer!

$100 + $1000 = $1100

$1100 + $250 = $1350

This is how you get the answer!

Step-by-step explanation:

Shamael

y = 9.2x

AED = 9.2(hours)

$9.20 an hour

Kamla

y = kx

  ([tex]x_{1} ,y_{1}[/tex]) = (5, 50.75)

  ([tex]x_{2}, y_{2}[/tex]) = (4, 40.60)

  k = [tex]\frac{y_{1}-y_{2}}{x_{1}-x_{2}}[/tex] = [tex]\frac{50.75-40.60}{5-4}[/tex] = [tex]\frac{10.15}{1}[/tex] = 10.15

AED = 10.15(hours)

$10.15 an hour

Willy is creating a garden this is the diagram of willy's garden what is the area of the garden he's going to build. 32ft,26ft,10ft driveway 20ft,7ft garden 14ft.

Answers

Answer:

the answer is 230 ft squared

Step-by-step explanation:

We can solve this by subtracting the area of the driveway from the entire rectangle

The area of a rectangle is , so multiplying 14 by 32, we get 448

Now we need to find the area of the driveway. We can split up the driveway into 2 rectangles, one big rectangle at the left and a tiny rectangle in the upper right.

To find the area of the big rectangle in the driveway, we multiply 10 by 20, getting 200.

To find the area of the tiny rectangle in the driveway, we subtract 20 from 26 to find the length, which is 6.

Now we need to find the width of the tiny rectangle. We can do this by subtracting 7 from 10, getting 3.

Multiplying 6 by 3, we get 18, so the area of the tiny rectangle is 18.

Adding 200 to 18, we get 218, so the area of the driveway is 218 ft squared.

Now we need to subtract 218 from 448.

448-218=230

In 2011 Tufts University had 17,000 applicants. Each year the number of applicants increased 11% from the previous year.

How many applicants would you expect Tufts University to have in 2013? Round to the nearest whole

Answers

Explanation: it’s up by 2 years each being 11% so just multiply that by 2 and just do
17,000 x 22% which is 17,000 x 0.22 = 3,740
So 17,000 + 3,740 = 20,740

Can someone plz help me with this??

Answers

Answer:

it's the second choice (3=3)

Answer:

y = - x + 4

Step-by-step explanation:

The equation of a line in slope- intercept form is

y = mx + c ( m is the slope and c the y- intercept )

Calculate m using the slope formula

m = [tex]\frac{y_{2}-y_{1} }{x_{2}-x_{1} }[/tex]

with (x₁, y₁ ) = (1, 3) and (x₂, y₂ ) = (3, 1)

m = [tex]\frac{1-3}{3-1}[/tex] = [tex]\frac{-2}{2}[/tex] = - 1 , then

y = - x + c ← is the partial equation

To find c substitute (1, 3 ) into the partial equation

3 = - 1 + c ⇒ c = 3 + 1 = 4

y = - x + 4 ← equation of line

Help! brainliest stars and hearts if correct! Please Area and perimeter! Please explain!

Answers

Answer:

Perimeter = 14 in

Area = 8 in^2

Step-by-step explanation:

Area = 2x2 + 4x1 = 8 in^2

Perimeter = 2+2+2+2+1+4+1 = 14 in

Answer:

The area is 8 square inches and the perimeter is 16 square inches.

Step-by-step explanation:

First, find the area.

We can find the area of the rectangle at the bottom pretty easily. Since half of the length of the bottom rectangle measures 2 inches, the full length would be 4 inches.

4 ⨯ 1 = 4

So, the area of the bottom rectangle is 4 square inches.

For the square on top, all you have to do is multiply 2 ⨯ 2, because there is no missing length we need to find out.

2 ⨯ 2 = 4

Now, we have to add 4 + 4, because the two quadrilaterals are joined together.

4 + 4 = 8

So, the area of the shape is 8 square inches.

Now, let's find the perimeter. We already know that the bottom rectangle's length is 4 inches, and that the sides are 1 inch tall. The square is 2 inches all around, so, no problems there.

Add the side measurements, not including the 2 inches at the bottom of the square because that side is inside the big shape.

2 + 2 + 2 + 4 + 1 + 4 + 1 = 16

So, the perimeter of the shape is 16 inches.

I have a question. It is: 5x+2y=4 3x+6y=-12 Solve the system of equations by graphing. How do I input that on a Casio graphing calculator. Giving brainliest if it works. Thanks!

Answers

Answer:

Step-by-step explanation:

  [1]    5x + 2y = 4

  [2]    3x + 6y = -12

Graphic Representation of the Equations :

   2y + 5x = 4        6y + 3x = -12  

 

// Solve equation [2] for the variable  y  

 

 [2]    6y = -3x - 12

 [2]    y = -x/2 - 2

// Plug this in for variable  y  in equation [1]

  [1]    5x + 2•(-x /2-2) = 4

  [1]    4x = 8

// Solve equation [1] for the variable  x  

  [1]    4x = 8  

  [1]    x = 2  

// By now we know this much :

   x = 2

   y = -x/2-2

// Use the  x  value to solve for  y  

   y = -(/2)(2)-2 = -3
