Answer:
Uranus : 15
Saturn : 18
Step-by-step explanation:
Uranus = U
Saturn = S
1) U= S - 3
2) U+ S = 33
1)* U - S = -3
2)* U + S = 33
1)* + 2)* 2U = 30, so U = 15
Then Saturn will have 18 (because they add up to 33)

Step-by-step explanation:
Answer:
x = 4y/3
Step-by-step explanation:
y = 3x/4
Multiply both sides by 4.
4y = 3x
Divide both sides by 3.
x = 4y/3
Answer:
8x + y = 5
Step-by-step explanation:
Start with the slope-intercept form y = mx + b. The y-intercept is (0, 5). Substituting -8 for m and 5 for b, we get:
y = mx + b => y = -8x + 5
Put this into "standard form" by adding 8x to both sides:
8x + y = 5
Since 2 cases = $48
÷ 48 by 2 to get the cost of one case of paper
48÷2=$24 per case
and each case has 12 pack of paper
so $24 for 12 packs of paper
180÷12=15, which gives you the number of case you need
15 cases × $24= $360 for 180 packs
