Answer:
T = 7.5
Step-by-step explanation:
One table = 4 students
? table = 30 students
To get the answer we criss-cross
30 * 1 = 4T(amount of table)
4T = 30
T = 30/4
There should be 8 tables but the last table has 2 people sitting on it rather than 4.
D. 5y^2 - 4y - 1
Combine like terms:
(y^2 -y +1) +(4y^2 -3y -2)
= y^2(1 +4) +y(-1-3) +(1 -2)
= 5y^2 -4y -1
3^0 if zero is an exponent then the answer would be 1.
11
5 x 2 =10
10+6=16
16-1=15
