Ben wants to go fishing on the lake

A boat rents for $12 per hour, and a rod and reel rent for $20 per day.

If Ben wants to spend no more than $80, how many hours can he soend fishing on the boat

Answers

Answer: Ben can only rent the boat for 5 hours.

Step-by-step explanation:

You have to set up an equation. It would be 20 + 12h = 80

20+12x=80

12x=80-20

Then divide both sides 12x=60

And you get 5

Ben can spend at most 6 hours (72 dollars) being on the boat.

Now if you wanna include the rod and reel, Ben can spend 29 hours (24 hours from the rod and reel, and 5 hours on the boat) Which all adds up to 80

Step-by-step explanation:

Subtract the number without the x from the answer then find a multiple of the number with the x for example

5x+2=17

17-2=15

Multiples

X1= 5

X2=10

X3= 15

Answer:

I hope this helps :)

Step-by-step explanation:

- 5x + 2 = 17 -- x = 3

- 3x + 5 = 36 -- x = 10.333

- x/3 - 14 = 9 -- x = 7.667 (Might be wrong)

- 73 = 3x - 20 -- x = 31

- 2x - 14 = 7 -- x = 10.5

- 53 = 9x - 1 -- x = 6

Step-by-step explanation:

Just need a little help and explanation on this one. I always mess up and get confused, which causes me to feel stressed

Answers

first you will convert -2 1/3 to an improper fraction which will leave you with -7/3 - (-5) then you remove the parentheses which will change -7/3 - -5 to -7/3+5 since two negatives = a positive. Then make the denominators the same by multiplying 5 by 3, then you have -7+15
———
3

then you will subtract -7+15 to get you
8/3 and then simplify the improper fraction to get the difference of 2 2/3

your final answer is 2 2/3

Tell whether each number is a solution to the problem modeled by the following equation.

Mystery Number: Five more than −8 times a number is 29. What is the number?

Let the mystery number be represented by n. The equation is 5+(−8)n = 29.

Is 3 a solution to the equation?

Is −4 a solution to the equation?

Answers

Answer:

Neither are a solution.

Step-by-step explanation:

The thing is, -4 * -8= 32+5 =37, and you're looking for 29.

3*-8=-24+5=19. If you meant to put positive 8 and not negative, then 3 would be right, but other than that, neither are correct.
