Answer
1.15 hours
Step-by-step explanation:
Assuming 115 is 115 km then you just move the decimal point twice and get 1.15!
For example - (Starting number) 115. (Moving decimal point) 115. -> 11.5 -> 1.15
Answer:
Step 1: Solve one of the equations for one of the variables. Let's solve the first equation for x
Thus, option A) is true.
The solution to the system of equations be:

Step-by-step explanation:
It is important to remember that when we solve the system of equations, the first step we need to do is to solve one of the equations for one of the variables.
Given the system of equations


Step 1: Solve one of the equations for one of the variables. Let's solve the first equation for x

Add y to both sides


Thus, option A) is true.
<u>NOW LET US SOLVE THE REMAINING PORTION</u>
to solve for y



For x = -1 + y
substitute y = 5


Thus, the solution to the system of equations be:

Answer:3+24b
Step-by-step explanation:
3(1+8b)
3+24b
C. Reflected over the y-axis and translated up 1 unit
Answer:

Step-by-step explanation:
We are given that

We have to find the value of given logarithms by using change-base formula
Base-change formula:

Where x=New base
Using the formula then, we get

Substitute the values 
Then,we get
