Answer:
Junior is 11 and Grandpa is 59
Step-by-step explanation:
G = 6J - 7 Get G by itself
G + J = 70
- J -J
G = -J + 70 Set the two equations equal to each other
6J - 7 = -J + 70
+J +J Add J to both sides
7J - 7 = 70
+ 7 +7 Add 7 to both sides
7J = 77 Divide both sdies by 7
J = 11

a/b=5/4
a=5k
b=4k
b/c=7/3
b=7x
c=3x
b=4k
b=7x
4k=7x =>
k=7y
x=4y
a/b/c=
=5*7*y/4*7*y/3*4*y=
=35y/28y/12y=
=35/28/12y=
=5/4/12y=
=1,25/12y=
=0.1041666666666667/ y
there may be a mistake in my answer
(5 + 4 - 2) x (-2)
= (9 - 2) x (-2)
= (7) x (-2)
= - 14 (Answer A)
