Answer:
x=6
Step-by-step explanation:
x-7=-1 add -1 to other side of the equation
x-6=0 add six to the zero
x=6
For this case we have the number in exponential notation:

We observe that the exponent of the exponential notation is positive.
Therefore, to express the number as a whole number, we must move the comma 6 spaces to the right.
We have then:

Answer:
this distance written as a whole number is:
miles

Step-by-step explanation:
Answer:
x = 3
Step-by-step explanation:
Given
f(x) = - 10x + 45 and f(x) = 15, then equating gives
- 10x + 45 = 15 ( subtract 45 from both sides )
- 10x = - 30 ( divide both sides by - 10 )
x = 3
