Roy weighs 150 pounds and plans to lose 1.5 pounds a week. Luis weighs 200 pounds and plans to lose 2.5 pounds a week. Which equation shows when Roy and Luis will weigh the same? Use w for the number of weeks.
a 150 + 1.5w = 200 + 2.5w
b 350 = -4w
c 150w - 1.5 = 200w - 2.5
d 150 - 1.5w = 200 - 2.5w

d 150 - 1.5w = 200 - 2.5w

Step-by-step explanation:

To write an expression for this problem, we call:

= number of weeks

Roy weighs 150 pounds at the beginning, and he plans to lose 1.5 pounds per week; this means that his weight after w weeks is

Luis weighs 200 pounds at the beginning, and his weight decreases by 2.5 pounds per week, so the expression for his weight after w weeks is

Roy and Luis have the same weight when

Therefore,

Which is option D.

what is the approximate angle of acb if abc is 25cm and the length of segment bc is 15

step-by-step explanation:

the camry sales+accord sale=828,000. to make it so the two numbers are 18 thousand apart and still equal 828,000, you first need to find out what half of 828,000 is. 828,000/2=414,000. for the two numbers to equal 828,000, you have to add the same amount as you subtract from the middle. in this case, the number is 9,000 because it's half of 18,000. to equal 828,000, you have to add 9,000 to 414,000 for the camry and subtract 9,000 from 414,000 for the accord. 414,000+9,000=423,000.

414,000-9,000=405,000.

423,000+405,000=828,000.

423,000-405,000=18,
