-3x + y = 22
-12x – 10y=-10

Answers

Answer 1

Answer:

              x = -5,  y = 7

Step-by-step explanation:

-3x + y = 22     ⇒  y = 3x + 22

-12x - 10y = -10  and  y = 3x + 22

-12x - 10(3x + 22) = -10

-12x - 30x - 220 = -10

               +220       +220

 - 42x  = 210  

 ÷(-42)     ÷(-42)

    x = -5

y = 3(-5) + 22 = -15 + 22 = 7

The volume of a pyramid, V, is calculated using the formula V = 1/3 AH, where A is the area of the base and H is the height of the pyramid.

Rearrange the formula to solve for the base area (A)

Answers

Answer:

A= 3V/H

Step-by-step explanation:

V=1/3 AH

multiply 3 on both sides

3V=AH

divide both sides by H

Answer:

144 cm²

Step-by-step explanation:

A prism's surface has 2 triangles & 3 rectangles.

In both the triangles , length of :

Perpendicular = 4 cm

Base = 6 cm

So , Area of both triangles = [tex]2(\frac{1}{2} * Base * Perpendicular) = 2(\frac{1}{2}* 6 * 4) = 24 cm^2[/tex]

In the 3 rectangles ,

Length = 8 cm

Width = 5 cm

So , Area of the rectangles = [tex]3( Length * Width) = 3(8 * 5) = 120 cm^2[/tex]

Hence the total surface area of the prism is = 120 + 24 =144 cm²

Joes mother gave him 1/3 of the money in her purse. His father gave him 5.00. If they gave joe a total of 12.00, How much money did his mother have in her purse. Joes mother had $ money in her purse (Enter a number only and make sure to include the decimal and 2 numerical decimal places.)

Answers

Answer:

$21

Step-by-step explanation:

let the money in her purse be $x

1/3 of the money is 1/3x

Since his father gave him $5 and the total amount became $12

the expression for the total amount would be

12= 1/3x+5

We can now solve for x

12-5= 1/3x

1/3x= 7

cross multiply we have

x= 7*3

x= $21

Therefore the money in joes mother's purse is $21

3x - 6 = 2(x + 4). find the value

Answers

3x -6 = 2(x + 4)
Multiply x by two and 4 by 2 to get
3x - 6 = 2x + 8
You want the x to be alone on one side so you add six on both sides to get rid of it to get:
3x = 2x + 14
You still don’t have just one x and it isn’t alone on one side, so you subtract 2x from both sides and get
x = 14

2m - n =8 Solve for n

Answers

Answer:

[tex] \boxed{\sf n = 2m - 8} [/tex]

Step-by-step explanation:

Solve for n:

⇒2m - n = 8

Subtract 2 m from both sides:

⇒2m - 2m - n = 8 - 2m

2m - 2m = 0:

⇒-n = 8 - 2 m

Multiply both sides by -1:

⇒-n × (-1) = (8 - 2m) × (-1)

⇒n = 2m - 8

The required value of n is equal to n = 2m - 8.

An expression is given in the question ; i.e., 2m - n = 8.

We have to find the value of the 'n' .

What is algebra ?

Algebra is the branch that deals with various symbols and the arithmetic operations such as addition , subtraction , etc.

As per the question ;

The given expression is 2m - n = 8.

Let's solve it to get the value of n.

The value of n can be find out , if we bring n to the left side of equal sign and 8 to the right of equal sign.

So ,

2m - n = 8 can be written as ;

2m = 8 + n

or

n = 2m - 8

Thus , the required value of n is equal to n = 2m - 8.
