A repair bill for a car is $648.45. The parts cost $265.95. The labor cost is $85 per hour. Write and solve an equation to find the number of hours of labor spent repairing the car

Answers

Answer 1

Answer:

( t - p ) /  85x =  h

( t - 265.95 ) /  85x  = h

648.45 - 265.95 / 85x = 3.32h

h = 3.32

Therefore ( t - p ) /  85x =  3.32

Step-by-step explanation:

648.45 - 265.95

282.50 /85

= 3.32 hrs

Finding equation to find hours can be shown as

( t - p ) /  85x =  3.32

How we found equation to find total

Parts = 19 x 14 - 5/100 = 266- 0.05

648.45 - 265.95 = 282.5

282.5/85 = 3.323  near to 3,233529

Labour = 85x  = 17 (5 + x)

Equation = 17(5+ x) + 14(19) - 5/100 = 648.45 where x = 85

Equation = ( 85x x 3  1/3) + 265 - 19/20 = t

Answer 2

The repair bill is an illustration of a linear equation. The equation that represents the scenario is: [tex]648.45= 265.95+ 85\times x[/tex]

And the solution (i.e. number of hours) is: 4.5 hours

Given that:

[tex]Bill = 648.45[/tex]

[tex]Parts = 265.95[/tex]

[tex]Labour = \$85[/tex] per hour

Let the number of hours spent be x

So, the equation is:

[tex]Bill = Parts + Labour \times x[/tex]

This gives;

[tex]648.45= 265.95+ 85\times x[/tex]

Collect like terms

[tex]648.45-265.95= 85\times x[/tex]

[tex]382.5= 85\times x[/tex]

Divide both sides by 85

[tex]4.5 =x[/tex]

[tex]x = 4.5[/tex]

Hence, the equation is:

[tex]648.45= 265.95+ 85\times x[/tex]

And the solution (i.e. number of hours) is: 4.5 hours

(b) her mother's age when she was born.​

Answers

Answer:

1) 130 degrees and 50 degrees 6) a price of a chair is 40, a price of the table is 80 7) a) 16 b)28

Step-by-step explanation:

1) Let it be that the first angle is x, The second one is y

1/5(x+y)=36- the first equation

1/2(x-y)=40- the second equation

The equations are simultaneous

x+y=180   and x-y=80

x+y+x-y=180+80

2x=260

x=130

y=50

6) The cost of a chair is x, the cost of table is y

6x+3y=480  2x+y=160

8x+y=400

8x+y- (2x+y)=400-160

6x=240

x=40

2*40+y=160

y=80

7) The Wan's age is x, the mother's age is y

x+y=60 x=60-y

Two years ago mother's age was y-2, when Wan;s age was x-2

y-2=(x-2)*3

y-2= (60-y-2)*3

y-2= (58-y)*3

y-2=174-3y

4y=176

y= 44

x=60-44=16- Wan's age now

44-16=28- her mother's age when she was born

Ivan currently has $ 45 saved. He had been saving $ 9 each week. You spent $ 126 of those savings yesterday. How many weeks have you been saving?

Write an equation that can be used to answer the previous question. First, choose the appropriate shape. Then fill in the blanks with the numbers 45, 9, and 126. Let w be the number of weeks.

please i need the procedure of this pls

Answers

9w + 45 = 126

Ivan earns $9 per week so we would write it as 9w
Add 45 to it because that is what he also saved
Then he spent those savings which was 126.
Now we can find how many weeks he was saving for.

First minus 45 from both sides
9w = 126 - 45 = 81

The divide both sides by 9
w = 9

Ivan has been saving for 9 weeks

Answers

Answer:

1361 ft.

Explanation:

The circumference of the wheel times the number of rotations equals distance travelled

Answer:

≈ 1361 ft

Step-by-step explanation:

One rotation is same distance as:

C = πd = 3.14*26 = 81.64 in

Total distance traveled:

200*81.64 = 16328 in

Convert inches to feet:

12 in = 1 ft16328 in = 16328/12 ft = 1360.66666667 ft ≈ 1361 ft

Answer:

2[tex]\sqrt{} 15[/tex] (decimal 7.74596)

Step-by-step explanation:

That sign is called a radical sign used to find square roots so it is used to extract or find the index of the number in this case the answer to that question

So you have

√6 √5 √2 first you find the value of the first number my finding the square root

(by changing the number into a decimal and using long division is the method i use)

Since √6 is √3 and √2 then you put them together like so

√2 √3 √5 √2

then you apply radical rule

(which the formula is √a √a = a,   a>0)

in this case it is √2 √2 = 2

and that equals

2 √3 √5

Apply radical rule again

(now that we did the formula the first time the formula changes now it is √a √b = √ab,    a>0, b>0)

now it is

2√3 x 5

now you just multiply 3 and 5and get 15

then you get

2[tex]\sqrt{} 15[/tex] (decimal 7.74596)
