Answer:
Step-by-step explanation:
If Amy started with 28 dollars and bought 7 pens, then had 20.30 dollars, we can subtract to find the price of all 7 pens.
28-20.30=7.70 dollars
now to find the amount for EACH pen, we divide by 7
7.70/7=1.1
each pen costed Amy 1 dollar and 10 cents with tax
is the expression that includes an exponent and has a value of 8
<em><u>Solution:</u></em>
Given that, Use the number 8, 6, and 2 and one operation to write an expression that includes an exponent and has a value of 8
We have to use each number only once
Given numbers are 8, 6, 2
Our expression should include exponent and the result should be 8
Among 6 and 2 we can use 2 for exponent
Raise 2 to power of 1
<em><u>The expression becomes:</u></em>

Here we have used one operation, that is addition
Verifying the expression

Thus the required expression is found
Answer: Divide Kayak budget by rental rate
Step-by-step Explanation:
As Joshua is renting for himself alone, the two available options would be the Single Kayak and the Single Sea Kayak.
He can determine the number of hours to rent a Kayak for by dividing his Kayak Budget by the rental rate per hour of the 2 options available to him.
<h2>
Single Kayak</h2>
Budget available = $50
Rental rate = $15 per hour
Hours he can rent = 50/15
= 3.33 hours
<h2>
Single Sea Kayak</h2>
Budget available = $50
Rental rate = $18 per hour
Hours he can rent = 50/18
= 2.78 hours
3x+3x+3x+y+3*2 ?
I only seperated the variabled number
One could be |x|<-2
This could be one since no matter what you put in for x, it will always be positive.
