Question

Can someone verify if this simple algebra question on my test is right or wrong?

Answer 1

See attached

Answer 2

I translated this as
G=2W-12
and
G+W=128
resulting in
128-W=2W-12

Answer 3

70 is correct

128 = 2A-12
12+128 = 2A

140 = 2A

70 = A

Answer 4

But it says COMBINED weight

Answer 5

why they use "w" for "Adam" is beyond me....

Answer 6

there formula, to me, implies 128 is just the weight of george

Answer 7

Yes, combined weight is George and Adam. And you figured out that equation correctly the first time :)

Answer 8

let me see it again..

Answer 9

for second one...should be 40..i feel

Answer 10

I get 46 2/3Lbs

Answer 11

G = 2A George is twice Adams weight....

Answer 12

G = 2A - 12

Answer 13

G + A = 128

Answer 14

2A - 12 + A - 128

Answer 15

3A = 128 + 12

Answer 16

gotta read thru my typos lol

Answer 17

3A = 140

A = 140/3 = 46 and some odd lbs

Answer 18

the test is worded wrong... human error :)

Answer 19

This isn't the first time ive got mis information from this school.
Thats why I come here to check. Sometimes they flutter up, sometimes its me.

Answer 20

You bring it to the teachers attention and they lok it over and make the correction to your grade. Perfection is an ideal, not a reality :)
