1. the answer is 24. think of x as the original amount, and y as the new amount. y times 1.5 is x, and y+12 is x. reverse that to figure out y, which is what we need, and you have x/1.5 = y as well as x-12 = y. Use the equal values method and make an equation x/1.5=x-12. solve this equation to get x, which is 36. to figure out the new amount, y, you need to subtract 12, which would help you get 24 as your final answer.
2. once again, create an equation. let's call team 1 x and team 2 y. team one has 1/4th as many as team 2, so that would be x=1/4y. An easier way to write that is 4x=y. after 6 people quit team two, that would be y-6. after the transfer, that would be y-6-12, and x+12 for the teams. they are equal after these, so y-6-12=x+12. solve this equation to get y-18= x+12. if you recall earlier, y was 4 times x, so substitute that into y to get 4x-18=x+12. Solve the equation to get 10 people on team one originally. your final answer is 10 people.
Answer:
20
Step-by-step explanation:
7 x 4 = 28
so you do 5 x 4 and get 20
Answer:
1/2 <3/4
Step-by-step explanation:
1/2 vs 3/4
We need a common denominator of 4
1/2*2/2 vs 3/4
2/4 vs 3/4
Since the denominators are the same, we compare the numerators
2 <3 so
2/4 < 3/4
1/2 <3/4
Find the horizontal and vertical distance between the points. First, subtract y2 - y1 to find the vertical distance. Then, subtract x2 - x1 to find the horizontal distance.
Number in the thousands place: 2
Number in the hundreds place: 4
Since 4<5, the number rounds down.
Final answer: 32,000
