Answer:

The sum of intigers are 57

Therefore,

n+n+1+n+2 =57

3+3n=57

3n=57-3

3n=54

n=54/3

n=18

Therefore,

n=18,

n+1=18+1=19

n+2=18+2=20

Your answer is 18,19,20

You can confirm it by adding them

Help with this please question 3
MrRissso [65]
3a. Jackson's gross pay for 40 hours is
  (40 h)×($12.20/h) = $488.00

3b. An equation for Jackson's pay could be
  372.10 = h×12.20
This can be solved for h by dividing by 12.20
  372.10/12.20 = h = 30.5
Jackson worked 30.5 hours last week.

3c. The total of hours shown is
  (8) + (7 1/4) + (8 1/2) = (8 +7 +8) +(0.25 +0.50) = 23.75
The number of hours missing is the difference between this number and the hours found in part (b).
  30.50 - 23.75 = 6.75
There are 6 3/4 hours missing from Jackson's time sheet for last week. This is less than a full day's work, so seems reasonable.

Of course, you know the decimal - fraction conversions:
  1/4 = 0.25
  1/2 = 0.50
  3/4 = 0.75

Answer:

a=7

Step-by-step explanation:

In ΔJKL, k = 3.7 cm, ∠K=15° and ∠L=41°. Find the length of j, to the nearest 10th of a centimeter.
Alexandra [31]

Answer:

The length of side j is 11.85cm

Step-by-step explanation:

Given that

In triangle JKL,

\angle k=15

\angle l=41

Side k=LJ=3.7cm

To find side j=KL:

By using sine rule,

We can write as

\frac{SinK}{LJ} = \frac{SinL}{JK} = \frac{SinJ}{KL} \\\frac{Sin15}{3.7} = \frac{Sin41}{JK} = \frac{SinJ}{KL}

Using property of triangle,

\angle k+\angle l+\angle j=180

15+41+\angle j=180

\angle j=124

\frac{Sin15}{3.7} = \frac{Sin41}{JK} = \frac{Sin124}{KL}\\\frac{Sin15}{3.7} = \frac{Sin124}{KL}\\KL=3.7\frac{Sin124}{Sin15}\\KL=3.7\frac{0.8290}{0.2588}\\KL=11.85cm

Thus,

The length of side j is 11.85cm
