Answer:
4 students
Step-by-step explanation:
The total number of students is given by:

Where N is the total number of students, A is the number of students that have taken Math 2A, B is the number of students that have taken Math 2B, and C is the number of students that have taken Math 2C:

4 students in Group A have taken all three classes.
*The number of students that have taken two classes has be subtracted so those students do not get counted twice
I always find that decimals are easier to work with so 5/8 as a decimal is 0.625. So 0.625 compared to 0.58 is bigger, so 5/8 is bigger than 0.58.
15% = 0.15 and 1/5 = 0.2 So 1/5 is bigger than 15%
it will take Dominic 48 minutes to go 12 miles because it took him 4 minutes every mile so you just multiply 4 times 12
Answer:
9) p = 48
10) a = 3.6
Step-by-step explanation:
9) p/8 + 3 = 9
p/8 = 6
p = 48
10) 12a/4 + 18/3 = 20.4
4a + 6 = 20.4
4a = 14.4
a = 3.6

In order to evaluate the given function at x = -3, simply replace "x" in the function with -3 and solve.

<em>Multiply -4 and -3 in the function above.</em>

<em>Add 3 on both sides of the equation.</em>


<em>Add 2y on both sides of the equation.</em>


<em>Divide both sides of the equation by -3.</em>


Therefore, at x = -3, the value of y = -5. Hence, f(-3) = -5.
Answer:
f(-3) = -5
