Step 1: Assign variable for the unknown that we need to find.
Let 'x' be the licence fee for a car that cost $9,900.
Step 2: Set up a proportion based on the given information.
Step 3: Solve for x
To get x alone we need to undo whatever is done to x. So multiply 9900 on both sides of the equation.
Simplifying fraction on both sides of the equation, we get...
Conclusion:
<u>$88.24 is the licence fee for a car that cost $9,900.</u>
Answer:
- A. 79.4
- B. 84
- C. Science class
Step-by-step explanation:
<u>Average test score in math class</u>
<u>Average test score in science class</u>
As per table the rate of change is -2, therefore g(x) is
- g(x) = -2x + 88, because
- g(1) = -2 + 88 = 86
<u>Part A: Determine the test average for your math class after completing test 2. </u>
-
f(2) = 0.2*2 + 79 = 0.4 + 79 = 79.4
<u>Part B: Determine the test average for your science class after completing test 2</u>
-
g(2) = 84 given in the table
<u>Part C: Which class had a higher average after completing test 4? </u>
- f(4) = 0.2*4 + 79 = 0.8+ 79 = 79.8
- g(4) = -2*4 + 88 = - 8 + 88 = 80
Science class had higher class
Answer:
none of the above?
Step-by-step explanation:
so the angles of the triangles are A1+A2+A3=360
so (4x+7)+(11x-9)+32=360
combine like terms
15x+30=360
isolate the variable
15x=330
x=22
angle ACB is 4x+7
4(22)+7=
88+7=
95
regardless of the sign of either "x" and "y".
