15. aime, seamus and shane were discussing how long it took them to complete their
hw. aime spent twice as long as seamus doing his homework. shane spent 45 minutes
less than seamus did. write an expression to represent the total amount of time all the
students did hw.

x + 2x + (x - 45)

Step-by-step explanation:

seamus is x

aime is twice seamus so multiply x by 2

shane did it 45 less than seamus so subtract by 45

d. is the correct answer

step-by-step explanation:

stew reads at the fastest rate of 265 words per minute.

step-by-step explanation:

it's a given that felicia reads at 260 word per minute and on connie's graph we can see that she reads 200 words per minute. since stew's table tells us that he read 795 in 3 minutes, we can divide 795 by 3 to find out how many words he reads per minute.

795/3 = 265

stew reads 265 words per minute - he reads at the fastest rate since felecia reads at 260 words per minute and connie reads at 200 words per minute.

stew (265) > felecia (260) > connie (200)
