Answer:
she read 165 words per minute
Step-by-step explanation:
if you tell us that Gillian read 3135 words in 19 minutes we can represent it as follows
19 m = 3135w
so now we have to find out how much I read in 1 minute, for this we have to divide both parts of equality by 19
19m = 3135w
19m/19 = 3135w/19
1m = 165w
she read 165 words per minute

Step-by-step explanation:sowwy..if am wrong QwQ
2.33 miles perhour for rowing without the wind
d + c = 19
100d + 15c = 1390
we can simplify the second equation
20d + 3c = 278
now d + c = 19
c = 19 - d
3c = 57 - 3d
now plug into second equation
20d + 57 - 3d = 278
17d = 278 - 57
17d = 221
d = 221 / 17
d = 13
now we can plug this into the first equation
13 + c = 19
c = 19 - 13
c = 6
