The way I figured this one out was saying that if it takes 2lbs to stretch it to 12 inches and 5lbs to stretch to 18 inches that means that 3 additional pounds = 6 inches. Therefore, each additional pound is 2 inches. We know already that with 2 lbs it was 12 inches in length and we can also say that 2 lbs = 4 inches. So subtract 4 from 12 and you end up with the answer of 8 inches.
5/8x + 1/5x can be written with a common denominator:
25/40x+ 8/40x = 99
This can be simplified to:
33/40x = 99
Next times both sides by 40
33x = 3960
Then, divide both sides by 33
x = 3960/33
x = 120
Answer:
2(x + 3) = x - 4
2x + 6 = x - 4 (Distribute 2)
x = -10 (Subtract x and 6)
I need the original equation so I can change it, other wise the problem is impossible
Answer:
ju12. Julle is looking through a catalogue for ice-cream. She can buy 2 L of triple-chocolate
Step-by-step explanation:
Julle is looking through a catalogue for ice-cream. She can buy 2 L of triple-chocolate
ice cream for $6.30 while the vanilla fudge ice-cream is usually $5.40 for 1.2 L.
What saving does there need to be on the price of the 1.2 L container of vanilla fudge
ice cream for it to be of equal value to the 2 L triple-chocolate container?
