You have to isolate the (a) so you multiply the 2/3 by 3/2 and you have to do that to the right side. So -24 times 3/2 equals to -36. Therefore, a=-36.
1 gallon of milk costs 0.50 more than 5 times a gallon of water.
From that information milk is 5x +0.50 the cost of water.
The cost of milk is $3.75, so now we have:
3.75 = 5x + 0.50
Subtract 0.50 from each side:
3.25 = 5x
Divide both sides by 5:
X = 3.25 / 5
x = 0.65
The cost of water = $0.65
You can read 100 pages in 5 hours.
40 pages in 2 hours. We need to get the unit rate. In this case, we need to get the number of pages read in 1 hour.
40 pages ÷ 2 hours = 20 pages per hour.
20 pages per hours * 5 hours = 100 pages.
Answer:
x+ (x+1) = 55
27, 28
Step-by-step explanation:
Let x = first number
x+1 is the next consecutive number
x+ (x+1) = 55
Combine like terms
2x+1 = 55
Subtract 1 from each side
2x+1-1 = 55-1
2x = 54
Divide by 2
2x/2 = 54/2
x = 27
The numbers are 27 and 28
Answer:
The average X bar would be 9.78
Take all players
Add them all together, you received 137
Then divide by the total number of players 14
147/14 = 9.79 with rounding to the second placement (100ths)
