Answer:

  • 80 minutes
  • 34.4 km

Step-by-step explanation:

Use the second equation to substitute for d in the first equation.

  0.43t = 0.33t +8

Subtract 0.33t from both sides

  0.10t = 8

Multiply by 10

  t = 80 . . . . . . Michelle will catch Jen in 80 minutes

The distance traveled will be ...

  d = 0.43t = 0.43×80 = 34.4 . . . . km

The girls will have traveled 34.4 km when they meet.

A tennis instructor chargers $40 for each one hour lesson and $25 for each half hour lesson if the instructors I come from 35 le
kaheart [24]
X = 1 hr lessons and y = 1/2 hr lessons

x + y = 35......y = 35 - x
40x + 25y = 1115

40x + 25(35 - x) = 1115
40x + 875 - 25x = 1115
40x - 25x = 1115 - 875
15x = 240
x = 240/15
x = 16 <=== there are 16 one-hr lessons
and 19 half-hr lessons

ad-work [718]

Answer:

The salary after four consecutive increase = $ 46794.34

Step-by-step explanation:

According to question,

salary of MR. John = $ 40000 per year

percentage py increase = 4%

Let the salary after four consecutive pay increase = x

So, X = 40000 (1 +\frac{4}{100})^4

Or, X = 40000 (\frac{26}{25})^4

Or, X = 46794.34

Hence the salary increase after four consecutive pay increase at 4% = $46794.34  Answer
