Answer:
Step-by-step explanation:
<u>3n+2 is divisible by p:</u>
<u>8n+3 is divisible by p:</u>
<u>Solve each equation for n:</u>
- n = (px - 2)/3
- n = (py - 3)/8
<u>Eliminate n and solve for p:</u>
- (px - 2)/3 = (py - 3)/8
- 8(px - 2) = 3(py - 3)
- 8px - 16 = 3py - 9
- 8px - 3py = 7
- p = 7/(8x - 3y)
As we see p could get 1 or 7 as natural number. Since 1 is excluded, the only solution is 7, and 8x - 3y must equal to 1.
Answer:50 cents. $5
Step-by-step explanation: each pound of sugar costs 50 cents. you can find that out by dividing the amount of sugar you have by the cost.
Easy! multiply the 6% by $8 then add it to the $8, now, multiply the 15% by the total of the cost with tax. then you all that to the total. ($9.75)
Opposite sides are parallel i.e W || Y & X || Z
