Answer:
a : b = 25 : 9
Step-by-step explanation:
(3a - 5b) : (3a + 5b) = 1 : 4
Product of extremes = product of means
(3a - 5b) *4 = (3a +5b) * 1 {Distributive property}
3a * 4 - 5b*4 = 3a + 5b
12a - 20b = 3a + 5b
Add 20b to both sides
12a = 3a + 5b + 20b
12a = 3a + 25b
Subtract 3a from both sides
12a - 3a = 25b
9a = 25b
a:b = 25 : 9
Answer: So, all you have to do is divide in this situation. He starts with a board that is 12 feet long, keep that in mind. If he cuts that into 8 pieces it's like he is dividing. So 12 divided by eight or 12/8 would be 1.5. Your answer is that each piece would be 1.5ft long.
2500 - 240 = 2260
2260/2= 1130 or female count 1130 + 240 = 1370 or male count\
1370 + 1130 = 2500
1 quart of the 16oz jug is $1.26 (.63x2) 1 quart of the half gallon is $1.12 (2.24/2) so 1.26-1.12= 0.14 the 16oz jugs are 14 cents more expensive than the half gallon
