Answer:
x=12 and y=1
to find the x value, you multiply the y value by 2.
6×2=12
to find y, you divide x by 2.
2/2=1
The cost per hour for renting the boat is $18 per hour.
A function is said to be linear if it is a straight line graph and it can be represented by the equation:
y = mx + b
where y, x are variables, m is the rate of change and b is the initial value of y.
Let y represent the total cost for renting the boat for x hours.
Given the equation:
y = 18x
Therefore the cost per hour for renting the boat is $18 per hour.

<h3>The number of beads lina has is 31</h3><h3>
Laura made a mistake by adding the constant 7 and variable 4b</h3>
<em><u>Solution:</u></em>
Given that,
Laura wrote and solved the following expression to find the total number of beads Lina has
There are 6 beads in each packet
7+4b = 11b
= 11(6)
=66
From given,
Lina has a total of 7 + 4b beads
Given that, There are 6 beads in each packet
Substitute b = 6
7 + 4(6)
Simplify
7 + 24
Add
31
Thus, she has a total of 31 beads and not 66 beads
Laura made a mistake by adding the constant 7 and variable 4b
But a constant and variable cannot be added
Answer:
Step-by-step explanation:
The layout looks like this.
r-----------s-----------------t
6.4
----------------9.3-----------
Now you want st so the formula is
rt = rs + st
9.3 = 6.4 + st Subtract 6.4 from both sides
9.3 - 6.4 = st Combine
st = 2.9
