Answer:
45$ per house cleaned
Step-by-step explanation:
135$ / 3 houses = 45
225$/ 5 houses = 45
Answer:
5sqrt(5)
Step-by-step explanation:
sqrt(45)+sqrt(20)
sqrt(9*5)+sqrt(4*5)
sqrt(9)sqrt(5)+sqrt(4)sqrt(5)
3sqrt(5)+2sqrt(5)
(3+2)sqrt(5)
5sqrt(5)
The cost before increase was $550.
Step-by-step explanation:
Given,
Increased price of plane ticket = $616
Increase percent = 12%
Let,
x be the original price of ticket.
Now,
The original price is 100% and 12% is increased, therefore;
New price = (100+12)% = 112%
Thus;
$616 is 112% of x.
112% of x = 616
Dividing both sides by 1.12
The cost before increase was $550.

Answer:
#16 = (0, -10)
#17 = (-18, -3)
Step-by-step explanation:
U wouldn't use the distance formula, you would need to use the Midpoint Formula, which is, M = (x1 + x2 / 2, y1 + y2 / 2). For #16, you plug in (4, -5) for M and 8 for x1 and 0 for y1, so the equation should look like this : (4, -5) = (8 + x2 / 2, 0 + y2 / 2). Then separate the equation to make it easier: 4 = 8 + x2 / 2 and the second equation : -5 = 0 + y2 / 2. So let's do the 1st equation, the first step would be to multiply the 2 to both sides. So the equation should look like this, 8 = 8 + x. Then subtract the 8 from both sides and you get 0 as your x. Now moving on to the 2nd equation, you multiply the 2 to both sides, and you get, -10 = 0 + y, as your equation, but since 0 won't affect it, -10 should be your y. Then just use these steps to solve #17, and your answer should be (-18, -3).
