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
zysi [14]

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

Factor out the highest common factor.<br><br>​
saw5 [17]

The highest common factor is found by multiplying all the factors which appear in both lists

a.(13-4b)(a+6)

13a-24b

13 and 24

so we have to factor this

13 =13×1

24=12×2=12 is 6×2=6 is 3×2=3 is 3×1=3×1

Therefore 1 and 1 get canceled

13×3=39

(a )39

like this we have to solve........
