User=2 anor=5 to determine if the two expressions are equivalent
1+2+)-12 8+2-6
Complete the statements
When r=2 the first expression is
When r=2 the second expression is 6
When r=5, the first expression is 21
When r=5. the second expression is
The expressions are not equivalent

12x+4x-7y+45b+78a-44b+1a+1z+0d+1.1a+1.1a+2+2+2

just sum

10 + 10 = 20

sinn is the total amount of students now and m were the students before, you subtract them both (n-m) and divide that by m. then, since to get a percentage from a fraction you have to multiply by 100, your answer should look like this: n-m/m*100
