Answer:
20 students in science class, 25 in math
Step-by-step explanation:
so let 1 classroom= x
so the other classroom= x+5
if there is a total of 45 students
x+x+5=45
2x=45-5
2x=40
x=20
12 holes in 6 minutes.....12/6 = 2 holes per minute
in 25 minutes...
25 * 2 = 50 holes in 25 minutes <==
Answer:
(2,4)
Step-by-step explanation:
that would be the answer because when you reflect it over the Y axis you are making the y turn into a + or - depending on what it already is if y=-4 when you reflect it over the y it would be y=4
I would think that it is B. because it makes the most sense to me. it also could be B. for one other reason and that is converting helps to understand how to salve it on pencil and paper if you know how to convert on paper
so my answer would be B.
You use PEMDAS.
First, parentheses
(x+4) = 4x
(3x+5) = 3x+5
So, that is
4x*3x+5
Then, exponents. We don’t have any.
Then, multiplying.
4x*3x is 12x
So, 12x+5
And then, division. We don’t have anything to divide.
Then, addition and subtraction
You can’t add the variable to a number, so the answer is just
12x+5.
Hope it helped. :)
