Ok so 7 times 4 is 28 so she read 28 the first day. For the second day since 40-28= 12, 12 divided by 2 is 6. So she read 6 pages per hour.
Step-by-step explanation:
given Tony can type at a constant rate of 110 words every 2 minutes.This means tony can type 55 words in every minute.
A- Tony can type W words in T minutes. W*T=M (M=Minutes Tony typed)
B- Tony can type 1100 words in 20 minutes. as 55*20=1100.
C- Yes, Tony can type the essay. Why: because in this equation w=55 and t=30 minutes so t*w=30*55=1650 so yes, Tony can write the essay.
10d+5n=220
divide both sides by 5
2d+n=44
d=13+n
sub 13+n for d in other equatin
2(13+n)+n=44
26+2n+n=44
26+3n=44
minus 26 both sides
3n=18
divide both sides by 3
n=6
sub back
d=13+n
d=13+6
d=19

Answer:
33 chips
Step-by-step explanation:
c= (700 - 464) ÷ 7 = 33
She can use 33 chips or less. I less cause she shouldn't eat too much calories.
