Answer:
4
Step-by-step explanation:
to solve | a | - | b | + | c | we need to plug in the given values
a = -8
b = -5
c = 1
the | | bars mean absolute value which is the exact value a number is away from 0 on a number line. an absolute value has to be positive, not a negative, as you cant be negative spaces away from something. plugging in the values into the equation we have:
| -8 | - | -5 | + | 1 |
the absolute value of -8 is 8, as -8 is 8 units away from 0 on a number line
like wise with -5, the absolute value of -5 is 5, as -5 is 5 units away from 0 on a number line
1 is the absolute value of 1 as its 1 unit away from 0 on a number line
the new expression looks like the following:
8 - 5 + 1
now we just add/subtract
8 -5 = 3
3 + 1 = 4
the solution to this expression is 4
The correct answer would be c. Hope this helps!

Answer:
42
Step-by-step explanation:
Number of students whose favorite class is Math:
60*0.85=51
Number of students whose favorite class is Science:
15% is equal to 0.15.
60*0.15=9
Subtract number of students who like science from number of students who like math.
51-9=42
42 more students in the survey prefer math over science.
