In Jim's class, 5 times as many students take the bus as those who walk. A total of 24 students walk or take the bus. How many m
lana [24]
The answer is 16.  To solve this problem, it will look like this:
5 n + n = 24
So, 6(4) = 24. n=4
With this equation, you can see that 4 kids walk to school and 20 take the bus. Then you need to do 20 - 4 = 16. So 16 more kids take the bus than walk to school. 

Another way to look at it...
We know there are 5 times as many bus kids as there are walkers. 
walkers - n
bus kids - n+n+n+n+n
6n = 24 (the total number of students), which can translate to 6 x n = 24. We know that 6x4=24, so n=4. The number of kids that walk is 4. The number of kids on the bus is 20. So subtract the bus kids from the walking kids, and that leaves us the answer. 16 more students ride the bus than those who walk. I hope that helped.

Find the value of JN in the figure. ​
yarga [219]

Answer:

JN = 32

Step-by-step explanation:

Δ JMN and Δ JKL are similar ( AA postulate )

then the ratios of corresponding sides are in proportion, that is

\frac{JM}{JK} = \frac{JN}{JL} ( substitute values )

\frac{24}{33} = \frac{JN}{JN+12}

\frac{8}{11} = \frac{JN}{JN+12} ( cross- multiply )

11 JN  = 8(JN + 12)

11 JN = 8 JN + 96 ( subtract 8 JN from both sides )

3 JN = 96 ( divide both sides by 3 )

JN = 32
