<span>A water tank is 1/8 full. The tank is 3/4 full when 42 gallons are added to the tank. How much water was originally in the tank? (I rewrote it, your wording was messed up)
3/4 = 6/8
1/8 + 6/8 = 7/8 = 42 gallons
42 divided by 8 = 5 1/4
So, the answer is 5 1/4. The tank originally 5.25 gallons of water.</span>
Answer:
(2x + 16)/3x = 2/1
2x + 16 = 6x
4x = 16
x = 4
Aaliyah's pens = 2x = 2 × 4 = 8
the number of Maria's pen = 3x = 3 × 4 = 12 -----Part A
New ratio = (8 + 16)/6
24/6 = 4/1 = 4 : 1 --------- Part B Step-by-step explanation:
Line HJ is parallel to a line that has a slope of 3 and a y-int at (0,0). If you wrote this in slope intercept form, it is y=3x+0. The only line that has such a slope is the red one.
Easy, the difference between 72 and 90 is 18, so you just take 18 divided for 72 to get the percent change which equal 0.25 or 25%. Hoped it help!
