Answer:
Step-by-step explanation:
The base price is 10 dollars.
(10)
For every ride she goes on, Caroline must pay 2 dollars.
(2r)
So, add them together.
10 + 2r
For 8 rides, replace r for 8.
10 + 2 x 8
10 + 16
$26

Answer:
8
Step-by-step explanation:
Given algebraic expression:
5(x - 1) - 2
To:
Evaluate this expression using x = 3
Solution:
Evaluate by plugging x = 3 to this expression:
Simplify using PEMDAS.
<u>We can conclude:</u>
By evaluating x = 3 to the given expression,the answer will be 8.
Commission is earning a certain percentage of the total sold price.
To figure this out we need to find what is 3% of $120,000
We can do this by multiplying 3% and $120,000
First let's change 3% into a decimal.
3% = 0.03
Now lets multiply.
0.03 x $120,000 = $3,600
So this person earned $3,600 in commission.
Good Luck! :)

Answer:
#1. Identity #2. 0 #3. No solution
Step-by-step explanation:
#1.
5y + 2 = (1/2)(10y+4)
5y + 2 = 5y + 2
This would be identity as the equation of the left and right are the same. This is not to be confused with no solution(explained below).
#2.
0.5b + 4 = 2(b+2)
0.5b + 4 = 2b + 4
0.5 b - 2b = 0
b = 0
#3.
-3x + 5 = -3x + 10
This equation has no solution because when you try to bring the -3x to one side, the x variable itself gets eliminated. So, how is it different from identity? Well in the first equation, it is true that when we try to bring the 5y one side it eliminates the y variable, however, that is also true for the constants(since if we try to bring the 2 to one side, it will be 2-2 which will equal 0, thus eliminating each other), but in this case, even if we remove the x, the constants will not equal 0, thus it will have no solution.
