Answer:
89/100
Step-by-step explanation:
The average weighted by the number of students is ...
(90(0.90) +10(0.80))/100 = (81 +8)/100 = 89/100
First simplify the expression as much as possible.
2x - x + 5
2x - x = x
x + 5
There are two terms, x and 5. expressions that have two terms are known as binomials
binomials should be your answer.
