Carla is renting a canoe. It’s cost $80 for 2 hours and $160 for 4 hours. What is the rate per hour?
patriot [66]
<span>Carla is renting a canoe. It’s cost $80 for 2 hours and $160 for 4 hours. What is the rate per hour?

If we want to get a full understanding of this question we must use the information given.

If renting the canoe cost $80 per 2 hours, to get 1 hour we must divide $80 by 2.

</span>\frac{80}{2}=40

or $40

We can also use $160 and 4 hours

\frac{160}{4}=40

or $40

So the rate per hour is $40

Which equation has a solution of k = 6.5?
olga_2 [115]
Answer:

-7k = -45.5

Explanation:

You can solve this by plugging in the “k” to the problems that are listed.
If you were to plug 6.5 in for all those problems, you’d get:

-3(6.5) = -19.5

-1 + 6.5 = 5.5

-7(6.5) = -45.5

-2 + 6.5 = 4.5

So, in this case, looking at the ones I answered and looking at the problems listed, the correct answer would have to be -7k = -45.5.

Rewrite the equation for x, and express its value in terms of a. 3/a x - 4 = 20
My name is Ann [436]

For this case, we must clear variable "x" from the given equation, expressed in terms of "a".

We have:

3/a x-4=20

By clearing "x" we have:

Adding 4 to both sides of the equation:

3/a x = 20 + 4

Multiplying by a/3 on both sides of the equation:

x=24a/3

x=8a

So, x=8a

Answer:

x=8a
