Use the fact that integrals are additive on their intervals. Mathematically, if ![c\in[a,b]](https://tex.z-dn.net/?f=c%5Cin%5Ba%2Cb%5D)
, then
So we have
Answer:
6x+2
Step-by-step explanation:
Well, the Pythagorean theorem is helpful.
Does 7^2+19^2=25^2?
no it desn't, so no it is not a right triangle
His work should have looked like this.
2x + y = 5
x − 2y = 10
y = 5 − 2x
x − 2(5 − 2x) = 10
x − 10 + 4x = 10
5x − 10 = 10 When he added in both sides, he subtracted 10 from 10,
5x = 20 instead of adding 10 from 10 to make 20.
x = 4
2(4) + y = 5
8 + y = 5
y = -3
There are a total of 2,000 students in the school.
1.) There are 540 students in the 6th grade. 540 is only 27% of students compared to the total. To find the total students in the whole school, we divide 540 by 27%.
2.) We first change 27% into a decimal by moving the point two times to the left. (Rule to change the percent into a decimal)
27% = .27
3.) Before we divide, we remove the decimal by moving the decimal two times to the right and so do we to 540.
.27 = 27
540. = 54000.
4.) Now we have 54000 divided by 27 which give us the answer of 2,000.
