Answer:
E = 8
Step-by-step explanation:
y - x = 4
y - (3y) = 4
y - 3y = 4
2y = 4
y = 4/2
y = 2
x = 3y
x = 3×2
x = 6
x + y = 2+6
x+y = 8

Answer:
The answer is: The largest number is 15.
Step-by-step explanation:
Let n = the number
n + (n + 1) + (n + 2) + (n + 3) = (n + 4) + (n + 5) + (n + 6)
4n + 6 = 3n + 15
n = 9
Proof:
9 + 10 + 11 + 12 = 19 + 23 = 42
13 + 14 + 15 = 27 + 15 = 42
Hope this helps! Have an Awesome Day!! :-)
Answer:
$191.70
Step-by-step explanation:
total amount spent = cost of medicine + cost of tax + cost of shipping
cost of tax = 0.05 x $180 = $9
cost of shipping 0.015 x $180 = $2.70
total cost = $180 + $9 + 2.70 = $191.70
