<u>Answer:</u>
4
<u>Step-by-step explanation:</u>
We are given that a PE class has 12 boys and 8 girls. The teacher needs to divide in maximum number of teams so that each team has an equal number of boys and girls.
For this, we will factors of 12 and 8 and their greatest common factor.
12 = 4 × 3 = 2 × 2 × 3
8 = 4 × 2 = 2 × 2 × 2
The greatest common factor is 4, therefore the maximum number of teams with equal number of boys and girls is 4.
Y-7=-2(x+1)
Y-7=-2x-2
Y=-2x+5
N - 1 = 1st number
n = middle number
n + 1 = 3rd number
(n - 1) + n + (n + 1) = 3n <== ur expression
-2,-7 because you go the same ammount in the opposite direction
I think its by typing it in the calculator.
