Answer:
The expression is equal to 
Step-by-step explanation:
Let
x ----> the number of hours that the roller blades are rented
y ----> the cost of renting roller blades in dollars
we know that
The linear equation in slope intercept form is equal to
where
m is the slope or unit rate of the linear equation
b is the y-intercept or initial value of the linear equation
In this problem we have
The slope is equal to
The y-intercept is equal to
----> value of y when the value of x is equal to zero
substitute
For x=h hours
substitute
Answer:
or
Step-by-step explanation:
The expression 
can be simplified by first writing the fraction under one single radical instead of two.
5/15 simplifies because both share the same factor 5.
It becomes 
This can simplify further by breaking apart the radical.
A radical cannot be left in the denominator, so rationalize it by multiplying by √3 to numerator and denominator.

Step-by-step explanation:
6 flower seeds $2
12 flower seeds $4
18 flower seeds $6
24 flower seeds $8
30 flower seeds $10
The value of x is 4. The steps to solving the equation are to use distributive property first so that the equation then looks like this: 10x+20=5x+40
Next you would combine like terms and then the equation would look like this: 5x+20=40
Then you would use the subtraction property of equality to subtract 20 from 40 so your equation will now look like this: 5x=20
Then you use the division property of equality to divide 20 by 5 to get x=4
Answer:
x = 25
Step-by-step explanation:
50 + 2x = 100
=> 2x = 50
=> x = 25
