Answer:
16.25
Step-by-step explanation:
Well, the school is 13/2 miles away.
13/2 = 6.5
Since Edward goes by car there and back, he travels 13 miles a day.
6.5 x 2 = 13
He went for 5 days.
5 x 13 = 65
The car consumed 4 gallons of gas by driving those 65 miles.
65 / 4 = 16.25
Therefore, Edward's car gets 16.25 miles per gallon!
Answer:
Inverse Function: f^-1(x) = 9/4x + 9
Step-by-step explanation:
To find the inverse function we can interchange the position of the variables x and y, and then solve for y;
y = 4/9x - 4 => x = 4/9y - 4,
x = 4/9y - 4,
4/9y = x + 4,
y = 9/4x + 9/4(4),
y = 9/4x + 9/ f^-1(x) = 9/4x + 9
Answer:
x = 20
Step-by-step explanation:
These angles are equal to each other because they are vertical angles.
Hence, we can equal the two measurements together to solve for x:
3x + 50 = 6x - 10
3x + 60 = 6x
60 = 3x
20 = x
Check your work:
3(20) + 50 = 6(20) - 10
60 + 50 = 120 - 10
110 = 110
