5(4x-7) +3 (3x+3) can someone help me please
ivann1987 [24]

Answer:

The expression 5(4x - 7) + 3(3x + 3) can be simplified to 29x - 26

Step-by-step explanation:

The first step in solving this is to apply coefficients to the contents of the brackets:

5(4x - 7) + 3(3x + 3)

= 5 × 4x - 5 × 7 + 3 × 3x + 3 × 3

= 20x - 35 + 9x + 9

Now you can group like terms:

20x - 35 + 9x + 9

= 20x  + 9x - 35 + 9

= (20 + 9)x - 26

= 29x - 26

And that is the final answer.

1 ) During his morning commute to work in rush hour traffic, Justin's average speed was 30 mi/h. During his afternoon commute ba
Hitman42 [59]

Answer:45 mi/h

Step-by-step explanation:

Recall: Speed = distance / time

Let the time taken for the morning journey be t_{1} and the time taken for the afternoon journey be t_{1} ,and the distance covered be d

that means for the first journey,

30 = \frac{d}{t_{1}}

d = 30 t_{1}

Also for the afternoon journey,

d = 60 t_{2}

Equating the two , since the same distance is being covered , we have

30 t_{1} = 60 t_{2}

that is

t_{1} = \frac{60t_{2}}{30}

t_{1} = 2 t_{2}

Also ,

total distance covered = 30 t_{1} + 60 t_{2}

Average speed = total distance / total time

 = 30 t_{1} + 60 t_{2} / t_{1} +t_{2}

  Recall that   t_{1} = 2 t_{2} , substitute this  into the formula for average speed , then we have

Average speed = 30(2t_{2}) +60 t_{2} / 3t_{2}

Average speed = 120t_{2} / 3t_{2}

Therefore :

Average speed = 40 mi/hr
