Answer: 5 benches and 23 students
Step-by-step explanation:
I will answer in English.
We have E students and B benches.
If we sit 4 students per bench, we have 3 students left.
then:
E = 4*B + 3
And if we sit 5 students per bench, there are two places with no students sited.
E = 5*B - 2
now we can replace the E in the second equation with the right part in the first equation:
4*B + 3 = 5*B - 2
3 + 2 = 5*B - 4*B
5 = B
So we have 5 benches, and:
E = 4*5 + 3 = 23 students.
Answer:
Step-by-step explanation:
add each number together
each of them should equal 88
then divide it by how many numbers there are. So it's 8.
this equals 11
Answer:
Assume that the number is 100. Then, 20% of 100 is 20×100100 = 20. Increasing 100 by 20% means increasing 100 by 20 and the resultant number is 120.
Answer:
This problem is acually really simple.
Step-by-step explanation:
all you have to do is replace the a with a 3. SO It would look like this:
g(x)=3f(x)
hope this helps :)
Answer:
A function only
Step-by-step explanation:
This situation represents a function only. Air pressure is the independent (input) variable and the weight of the candy dispensed is the dependent variabe:
weight = 3(pressure on the lever)
This has the form of a function, as well as of a direct proportion.
