Answer:
75
Step-by-step explanation:
In running 0.6 miles, you have gone from 300 remaining to 255 remaining, so have burned ...
300 -255 = 45 . . . . . calories
The rate in calories per mile is ...
(45 cal)/(0.6 mi) = 75 cal/mi
At the rate of the first 0.6 miles, you will burn 75 calories running 1 mile.
Answer:
525
Step-by-step explanation:

Answer:
8
Step-by-step explanation:
Your equation would be 8x - 4 = 60.
So,
8x - 4 = 60
+ 4 + 4
8x = 64
/8 /8
x = 8
Answer:the independent variable is x, the number of hours of work.
The dependent variable is y, the total charge for x hours of work.
Step-by-step explanation:
A change in the value of the independent variable causes a corresponding change in the value of in dependent variable. Thus, the dependent variable is is output while the independent variable is the input
For each visit, he charges $25 plus $20 per hour of work. The linear expression that represents the total amount of money that Ethan earns per visit is y = 25 + 20x.
Since the total amount charged, y depends on the number of hours of work, x, it means that the dependent variable is y and the independent variable is x
Answer:
The set of natural numbers is the set of all positive integers, then this set is:
{1, 2, 3, ...}
and the 24th letter of the alphabet is x
Now we want to write the expression given in the sentence "It is one more than the sum of the first three natural numbers, followed by the 24th letter of the alphabet"
We can "break" this in parts, so it is easier to understand.
Then:
"...the sum of the first 3 natural numbers..."
is:
1 + 2 + 3
Then:
"...the sum of the first 3 natural numbers, followed by the 24th letter of the alphabet"
This can be written as:
(1 + 2 + 3) + x
Now we can analyze the complete sentence:
"It is one more than the sum of the first three natural numbers, followed by the 24th letter of the alphabet"
This is equal to the expression we found above plus one, then we can write this as:
[(1 + 2 + 3) + x] + 1
[6 + x] + 1
6 + x + 1
7 + x
