5x^2y is the greatest common factor
Answer:
<u>8/10 hours or 48 minutes.</u>
Step-by-step explanation:
State the problem as a rule of 3:
3/4 room --------- 3/5 hours
1 room ------------ x
x= 0.8 hours.
• How much is 0.8 hours in minutes?
0.8 * 60 = 48 minutes.
The <u><em>correct answer</em></u> is:
15 weeks
Explanation:
Let w be the number of weeks. Bill weighs 150 pounds and wants to gain 2 lbs per week; this gives us the expression 150+2w for Bill.
Jamal weighs 195 and wants to lose 1 pound per week; this gives us the expression 195-1w for Jamal.
To determine how many weeks it will take them to weigh the same, we set the two expressions equal:
150+2w=195-1w
Add 1w to each side:
150+2w+1w = 195-1w+1w
150+3w = 195
Subtract 150 from each side:
150+3w-150 = 195-150
3w = 45
Divide each side by 3:
3w/3 = 45/3
w = 15
The answer is the second one
