Answer:
$0.25r + $5 = $12.50
Step-by-step explanation:
r represents the amount of rides Lacy went on during the day. If you do the problem in the correct order, you will get the answer
Step 1)
Subtract 5 from both sides
$0.25r + 5 (-5) = 12.50 (-5)
Step 2)
Divide by 0.25
0.25r (Divided by 0.25) = 7.50 (Divided by 0.25)
Step 3)
Answer
r = 30 rides
Answer: 1350
Step-by-step explanation:
So 1.5 x 900= 1350
Answer:
a = 14
Step-by-step explanation:
<u>Step 1: Write out your problem</u>
f (a) = 5a + 14 | f (a) = 0
<u>Step 2: Solve</u>
f (a) = 5 (0) + 14 , Input a.
f (a) = 0 + 14 , 5 x 0 = 0
(a) = 14 , 0 + 14
a = 14
Answer:
Jonathan's solution 
is correct.
Step-by-step explanation:
Given system of equations are:
Now
The graph of the linear equation 
cuts the y-axis at the point 
and x-axis at 
And the graph of the linear equation 
cuts the y-axis at the point 
and x-axis at 
And their point of intersection is
And this is Jonathan's solution.
We can see from graph that point of intersection is
Area of a circle = pi * r^2
16pi=pi * r^2
Divide both sides by pi
16=r^2
Square root both sides
4=r
Diameter=2r=2*4=8 inches
