Answer:
6
Step-by-step explanation:
Note: f(x) = y
f(x) = 2x + 2 x = 2
Step 1: Plug in 2 into x.
f(x) = 2(2) + 2
Step 2: Then multiply 2 times 2.
f(x) = 4 + 2
Step 3: Add.
f(x) = 6
Well first you have find out how many miles she drove in march. To find that you have to divide 825 by 3. That equals 275. Well if she drove 4 times more you take 275 x 4 and that equals 1100. She drove 1100 miles.

Answer:
The correct answer is: The test had 10 4-point questions and 30 3-point questions.
Step-by-step explanation:
Let t be the number of 3-point questions on the test
and
f be the number of 4-point questions on the test
Then,
According to the given statement that the test had 40 problems
Eqn 1
And
According to given statement that the total points are 130
Eqn 2
These equations form a system of linear equations in two variables.
Elimination method or substitution method can be used to solve the system.
So, from equation 1:
Putting t = 40-f in equation 2
Subtracting 120 from both sides
Putting f = 10 in equation 1
Subtracting 10 from both sides
Hence,
Number of 3-point questions = t = 30
Number of 4-point questions = f = 10
So,
The correct answer is: The test had 10 4-point questions and 30 3-point questions.
