Answer:
x = 2/5
Step-by-step explanation:
Given:
7 + 5x = 3(y-2)
Rearrange this equation such that x is expressed in terms of y
7 + 5x = 3(y-2) (expand right side)
7 + 5x = y(3)-2(3)
7 + 5x = 3y-6 (subtract 7 from both sides)
5x = 3y - 6 - 7
5x = 3y - 13
we are given the y-value of the coordinate pair (? , 5)
simply substitute y=5 into the equation above
5x = 3y - 13
5x = 3(5) - 13
5x = 15 - 13
5x = 2 (divide both sides 5)
x = 2/5
Answer:
It will take the worm 7 days to get to the top of the well.
Step-by-step explanation:
the well is 37 feet deep
the worm climbs up 7 feet, but loses 2 feet through the night
That means the worm only really climbs 5 feet a day.
So, if you subtract 5 from 37, 6 times, you'll get 7 feet left to go. And sense the worm climbs 7 feet a day, the last day the worm will climb his way to the top without slipping back down.
Hopefully this makes sense.
Answer is D.
As we can observe, in column y
3,4,6,10,18
4-3 = 1
6-4 = 2
10-6 = 4
18-10 = 8
Answer:
36(5)^-2.
Step-by-step explanation:
5^-2 * 9
= 9(5)^-2
2^4 * 4 ^ -3
= 2^4 + (2^2)^-3
= 2^4 * 2^-6
= 2^-2
So the answer is
9(5^)-2 / 2^-2
= 9(5)^-2 * 2^2
= 4*9(5)^-2
= 36(5)^-2.
