What exactly do you want to know? make it clear??
Answer:
The original number is 72
Step-by-step explanation:
72 swapping digits around results in 27
1/3 of 72 = 24
24 + 3 = 27
7x + 5(x + 3) + 4x + x + 2 =
= 7x + 5x + 15 + 4x + x + 2 = 17x + 17
Answer:
x = 
Step-by-step explanation:
Given
y =
← multiply both sides by (5x - 2)
y(5x - 2) = 2x + 3 ← distribute left side
5xy - 2y = 2x + 3 ( add 2y to both sides )
5xy = 2x + 3 + 2y ( subtract 2x from both sides )
5xy - 2x = 3 + 2y ( factor out x from each term on the left side )
x(5y - 2) = 3 + 2y ← divide both sides by (5y - 2)
x = 
To find how much each pound of beans costs (assuming no tax), we get 19.75/2.5 (as we want to figure out how much 2.5 goes into 19.75) to get 7.90 as our cost per pound
