The bill for the repair of a computer was $179. The cost for parts was $44, and the labor charge was $45 per hour. How many hours did it take to repair the computer?


1. Define the variable (What do we not know?):


2. Write the equation .


3. Solve the equation.

Answers

Answer 1

Answer:

1. x is the amount of hours it took to repair the computer

2. 44+45x=$179

3. Around 3 hours

Step-by-step explanation:

44+45x=$179

Subtract 44 on both sides:

44-44+45x=179-42

45x=137

Divide 45 on both sides:

45x/45=137/45

x=3.044444444

Around 3 hours.

point k lies at (-3,4) Image

Answers

Answer:

[tex]k(x,y) --> k'(x,y-7)[/tex]

Step-by-step explanation:

Given

[tex]k = (-3,4)[/tex]

Translation: 7 units down

Required

Determine the rule to produce k'

When an (x,y) coordinate is translated down by h units, the resulting point is:

(x,y) --> (x, y - h)

In this case:

[tex]h = 7[/tex]

So, we have:

[tex]k(x,y) --> k'(x,y-7)[/tex]

Hence, option A answers the question.

Solving further to determine the coordinates of k'.

[tex]k = (-3,4)[/tex]

[tex]k' = (-3,4-7)[/tex]

[tex]k' = (-3,-3)[/tex]

Sarah competes in a long jump competition.
Her first jump is 4.25 m.
Her best jump is 12% more than this.
However, her best jump is 15% lower than the winning jump.
Work out the length of the winning jump.

Answers

Ok so her best jump equation would be
4.25x 1.12 = 4.76
Sarahs best jump = 4.76
The equation for the winning jump would be
4.76x 1.15 = 5.474
The winning jump would be = 5.474

Solve x2 - 16 = 59. What does x
equal?

Answers

Answer:

37.5

Step-by-step explanation:

Answer:  x = 75/2 = 37.5

Step by Step:

Solve for x:

2 x - 16 = 59

Hint: | Isolate terms with x to the left hand side.

Add 16 to both sides:

2 x + (16 - 16) = 16 + 59

Hint: | Look for the difference of two identical terms.

16 - 16 = 0:

2 x = 59 + 16

Hint: | Evaluate 59 + 16.

59 + 16 = 75:

2 x = 75

Hint: | Divide both sides by a constant to simplify the equation.

Divide both sides of 2 x = 75 by 2:

(2 x)/2 = 75/2

Hint: | Any nonzero number divided by itself is one.

2/2 = 1:

Answer:  x = 75/2 = 37.5

The lengths of the sides of a triangle are in the extended ratio 4:7:10. The perimeter of the triangle is 105 cm. What are the lengths of the sides?
The lengths of the sides of the triangle in cm are

Answers

Answer:

20cm, 28cm, 40cm

Step-by-step explanation:

Let the shortest side be 4x, the middle side be 7x and the longest side be 10x.

4x + 7x + 10x = 105

21x = 105

x = 105 ÷ 21

x = 5

Shortest side (4x) = 5 × 4

Shortest side (4x) = 20

Middle side (7x) = 7 × 4

Middle side (7x) = 28

Longest side (10x) = 10 × 4

Longest side (10x) = 40
