If 27% of the group voted to change its
bylaws and 43% voted against the change,
how many people did not vote? The group
has 810 members.

243 people did not vote

Step-by-step explanation:

First you would calculate the number of people who DID vote:

27% + 43% = 70% (this is how many people voted)

you would then subtract to find the percent of people who DIDNT vote:

100% - 70% = 30%

Finally you would convert the % into an actual number.

0.30 (or 30%) x 810 members = 243 members

So, 243 members didn't vote.

Hope this helps!

38.5

step-by-step explanation:

lets say, first number = r

second number = 3r+7

total = 49

(r)+(3r+7)= 49

4r+7 = 49

4r = 42

r = 42/4

r= 10.5

3r+7 = 3(10.5)+7 = 38.5
