Solve each system of linear equations by adding or subtracting.
4x - 5y = 7
3x + 5y = -14

Answer:

35 degrees

Step-by-step explanation:

Answer:

x = 35 degrees.

Step-by-step explanation:

If two lines intersect each other, then the angles across from each other will equal to one another. Because the angle across from x is 35 degrees, we know that x equals 35 degrees as well.

Complete question :

Doug earns $10.50 per hour working at a restaurant. On Friday he spent 1 3/4 hours cleaning, 2 1/3 hours doing paperwork, and 1 5/12 hours serving customers. What were Doug's earnings?A$46.97B$47.25C$53.00D$57.75

Answer:

$57.75

Step-by-step explanation:

The total hours spent working :

1 3/4 + 2 1/3 + 1 5/12

7/4 + 7/3 + 17/12

L.C.M = 12

(21 + 28 + 17) / 12

= 66 / 12

= 5 6/12

= 5 1/2

Hourly pay = $10. 50

Total earning :

Total hours * pay per hour

5.5 hours * $10.50

= $57.75

Answer: Work below.

3x+6 = 4x+3

6-3 = 4x - 3x

3 = x

or

3x+6 = 4x+3

3x - 4x = 3 - 6

-x = -3

x = 3

Answer:

m<a=36

m<b=175

m<c=92

m<d=93

m<e=144

Step-by-step explanation:

since the shape has 5 sides we can determine the sum of the measure of interior angels with the equation 180×(n-2). replacing n with 5 would bring us to 180×3 equalling 540. since all the angels must add up to 540 we can combine them together to get it to 15x=540. simplify to get x=36. sub in x in the equations.

Answer:

first equation=6

second equation=15

Third equation=

Step-by-step explanation:

2(3x+2)=2x+28

6x+4=2x+28

collect like terms

6x-2x=28-4

4x=24

Divide both sides by 4

4x/4=24/4

x=6

second equation

5y+13=43-3y

collect like terms

5y-3y=43-13

2y=30

Divide both sides by 2

2y/2=30/2

y=15

Third equation

4(2a+2)=8(2-3a)

8a+8=16-24a

collect like terms

8a+24a=16-8

32a=8

Divide both sides by 32

32a/32=8/32

a=1/4

1) The solution to the equation is x = 6.

2) The solution to the equation is y = -7.

3) The solution to the equation is a = 0.25

Given are three equations we need to solve for their variables,

1) 2(3x + 2) = 2x + 28

2) 5y + 13 = -43 - 3y

3) 4(2a + 2) = 8(2 - 3a)

Let's solve each equation step by step:

1) 2(3x + 2) = 2x + 28

Expanding the parentheses on the left side:

6x + 4 = 2x + 28

Next, let's isolate the variable terms on one side and the constant terms on the other side:

6x - 2x = 28 - 4

Combine like terms:

4x = 24

To solve for x, we need to isolate x by itself. Divide both sides of the equation by 4:

4x/4 = 24/4

x = 6

Therefore, the solution to the equation is x = 6.

2) 5y + 13 = -43 - 3y

Let's start by moving the variable terms to one side and the constant terms to the other side:

5y + 3y = -43 - 13

Combine like terms:

8y = -56

To solve for y, we divide both sides of the equation by 8:

8y/8 = -56/8

y = -7

Therefore, the solution to the equation is y = -7.

3) 4(2a + 2) = 8(2 - 3a)

First, distribute the multiplication on both sides:

8a + 8 = 16 - 24a

Next, let's group the variable terms on one side and the constant terms on the other side:

8a + 24a = 16 - 8

Combine like terms:

32a = 8

To solve for a, divide both sides of the equation by 32:

32a/32 = 8/32

a = 0.25

Therefore, the solution to the equation is a = 0.25.

The actual distance between the two cities is 60 miles.

An expression is a way of writing a statement with more than two variables or numbers with operations such as addition, subtraction, multiplication, and division.

Example: 2 + 3x + 4y = 7 is an expression.

We have,

The distance of 15 miles on a map is represented by 2 inches.

This means,

2 inches = 15 miles

Divide both sides by 2.

1 inch = 7.5 miles

Multiply 8 on both sides.

8 inches = 8 x 7.5 miles

8 inches = 60 miles

Thus,

The actual distance is 60 miles.

Answer:

iPhone 12!!!!!!!!!!!!

Answer:

The iphone 8

Step-by-step explanation:

To find the nth term of a geometric sequence we have the following equation

ar^(n-1)

where a is the first term

r the is the common ratio

n is the term

we can see that the first term for the iphone 12 is 800, the common ratio is .9 (1-.1), and we need the third term

Therefore the price of an iphone 12 after 3 years is

800*.9^(3-1)

which is 648

The iphone 8's first ter is 600 and the common ratio is .95 (1-.05)

using the same equation

600*.95^(3-1)

which is 541.5

Answer:

the percentage of the employees at sports shop work part time is 60%

Step-by-step explanation:

The computation of percentage of the employees at sports shop work part time is shown below:

= Part time ÷ total employees

= 30 ÷ (20 + 30)

= 30 ÷ 50

= 3 ÷ 5

= 60%

Hence, the percentage of the employees at sports shop work part time is 60%

Answer: The answer is 50%

Answer:

The adjacent angles are: 72 and 108

Step-by-step explanation:

Given

Angle Ratio = 3 : 2

Required

Find the measure of each angle

Let the angles be [tex]x\ and\ y.[/tex]

Such that:

[tex]x + y = 180[/tex] --- adjacent angles of a parallelogram

and

[tex]x : y = 3 : 2[/tex] --- given

Convert to fraction

[tex]\frac{x}{y} = \frac{3}{2}[/tex]

Cross Multiply:

[tex]2x = 3y[/tex]

Make x the subject:

[tex]x = \frac{3}{2}y[/tex]

[tex]x + y = 180[/tex] becomes

[tex]\frac{3}{2}y + y = 180[/tex]

Take LCM

[tex]\frac{3y + 2y}{2}= 180[/tex]

[tex]\frac{5y}{2}= 180[/tex]

[tex]y = \frac{2}{5} * 180[/tex]

[tex]y = 0.4 * 180[/tex]

[tex]y = 72[/tex]

Recall that:

[tex]x = \frac{3}{2}y[/tex]

[tex]x = \frac{3}{2} * 72[/tex]

[tex]x = 1.5 * 72[/tex]

[tex]x = 108[/tex]

Hence, the adjacent angles are: 72 and 108
