The boat top speed was 2 miles per hour less then 3/5 the cars top speed. The boats top speed was 73 miles per hour.what was the top speed of the car ?

Answers

Answer:

Word Problem. Hmm

The Interpretation of the first expression

Let boat top speed be x and car's top speed be y

x= 3y/5 – 2

From the question

x= 73miles per hr

73= 3y/5 - 2

3y/5 = 73+2

3y/5=75

y= 75x5/(3)

y=125miles per hr.

This is the car's top speed. Thanks

  B: 1/2(3) +10 = 11.5 ≠ 16

  C: 1/2(3) -10 = -8.5 ≠ 16

  D: 2(3) +10 = 16 . . . . . . this equation works

Answers

Answer:

? = 7x

Step-by-step explanation:

Lets simplify the equation first;

5x - 20 + ? = -20 + 12x

=> So now, we have to make the equation on the left equation congruent to the right equation:

It we already have -20 common on both sides, but we need to find out, what added by 5x gives us 12x,

=> So we can let the number we have to find out be y, and say:

5x + y = 12x

=> y = 12x - 5x

=> y = 7x

Therefore, ? = 7x
