Let 
and 
be the number of elves and reindeers, respectively.
We know that:
(so far 14 of them have arrived)
(each reindeer has 4 legs and each elf has two)
If we multiply the first equation by 2 we have 
, and if we subtract this equation from the second we have 
which implies 
.
So, there are 5 reindeers and 9 elves (remember that they have to sum up to 14).
The number of boys wear glasses are 156 boys.
In this question,
Total number of pupils in the school = 910
Ratio of boys = 3/7
Then, number of boys = 910 × 3/7
⇒ 130 × 3
⇒ 390
Ratio of boys wear glasses = 2/5
Then, number of boys wear glasses = 390 × 2/5
⇒ 78 × 2
⇒ 156
Hence we can conclude that the number of boys wear glasses are 156 boys.

By setting up a system of equations we can easily solve this problem. Let's denote Jane's working hours with x and Jack's working hours with y. Since they don't want to work more than 65 hours, the first equation is x+y=65. The second equation is 14x+7y=770. By solving this system of equation , we find that y=20 hours, which is Jack's maximum working hours.
Answer:
ow many students are enrolled in community colleges? ... How does the population of community college students break down by race/ethnicity and income? ... What percentage of community college students obtain a college credential? ... How many community college students complete their remedial requirements?
Step-by-step explanation:
Provisional National Center for Education Statistics (NCES) data on unduplicated year-round enrollment (as opposed to fall enrollment only) indicate that 8.2 million undergraduates were enrolled in public two-year colleges in 2018–19.
In fall 2018, 5.6 million students were enrolled in public, two-year colleges. About 2 million were full-time students, and 3.6 million were part-time.
The National Student Clearinghouse Research Center estimates that 5.4 million students were enrolled in public two-year colleges in fall 2019, down 1.4% from fall 2018.
However, these studies underestimate the number of community college students, as about 100 community colleges offer a small number of bachelor’s degree programs and thus are listed in NCES as four-year institutions. According to a CCRC analysis correcting for this misclassification, 6.7 million students were enrolled at community colleges in fall 2017, and nearly 10 million students enrolled at a community college at some point during the 2017-18 academic year.
