Answer:
The ratio of the number of Lisa’s stickers to the number of John’s stickers is 3/2
Step-by-step explanation:
Step 1
Let
x ----> the number of stickers that Lisa has
y ----> the number of stickers that John has
we know that
------> equation A
----> equation B
Solve the system by substitution
Substitute equation B in equation A and solve for y
Find the value of x
----->
therefore
Lisa has 36 stickers and John has 24 stickers
Step 2
Find the ratio of the number of Lisa’s stickers to the number of John’s stickers
so
x/y
substitute
Answer:
a
Step-by-step explanation:
R + g + b = 50
r = b + 6
g = b - 4
(b + 6) + (b - 4) + b = 50
3b + 2 = 50
3b = 50 - 2
3b = 48
b = 48/3
b = 16 <=== 16 blue marbles
r = b + 6
r = 16 + 6
r = 22 <=== 22 red marbles
g = b - 4
g = 16 - 4
g = 12 <=== 12 green marbles
