juan is preparing many gifts for a family holiday party. each gift must either be
wrapped with wrapping paper or prepared in a gift bag. juan can wrap a single gift in
6.5 minutes and he can do a giftbag in 3 minutes. juan prepared a total 19 gifts in
74.5 minutes. write a system of equations that could be used to determine the
number of gifts juan wrapped and the number of giftbags he prepared. define the
variables that you use to write the system.​

answer:

step-by-step explanation:

let travis' age be a.

so,

substitute a= 2b-62 in a + b=70. so, a in a+b becomes 2b-62

2b-62+ b can be rewritten as 2b+b-62   which is also 3b-62

so, this equation (2b-62+ b=70) becomes 3b-62=70

3b-62=70 ⇒ 3b=70+62 ⇒ 3b=132

b=132/3

b=44

but remember

now you know b, you can find a

a= 70-b

a=70-44

a=26

big boi's 44 years old, travis is 26

you can also check by plugging the values in the second equation

2(44) - 62 is 26

slope = 2/8. count up two, then counted 8 right to get to the second point

simplified slope: 1/4

(ignore the first dot in the 4th quadrant because it is behind the y intercept)!

hope this : ) brainliest?
