Answer:
0.10 or 10%
Step-by-step explanation:
Since each student must take at least 2 courses, if no student took all three courses, the sum of the percentages would total 200% (counting each student twice). Therefore, the proportion of students taking all three courses is the difference between the sum of all percentages and 200%:

0.10 or 10% of the students take all 3 courses.
Answer:
a=3
Step-by-step explanation:
opening the bracket, we have
4x-2x-2a=8
2x-2a=8
x=7
2(7)-2a=8
14-2a=8
collect like terms
-2a=8-14
-2a=-6
divide both sides by -2
a=3
Answer:
Y-Int = -12
Step-by-step explanation:
First, I would change the equation to slope intercept form:
-3y = 36 + 4x
3y = -36 - 4x
y = -12-4/3x
y = -4/3x - 12
Answer:
C(x) = 2x + 100
Step-by-step explanation:
Here, we want to find the formula for C(x)
Here, x will be the number of gallons of gas
so per day, if x gallons of gas were consumed, the daily cost here will be x * 2 = $2x
Adding the cost for the attendant, we have 2x + 100
So the formula for C(x) will be;
C(x) = 2x + 100
