Answer:
11%
Step-by-step explanation:
this is simple because there are 4 parts of the pie chart, and we are given 3. the one we don't know we will call x. Since its percents, we know that all of the percents will add up to 100, so we can write an equation.
45 + 23 + 21 + x = 100
to solve, you can subtract 45, 23, and 21 from both sides and you are left with x = 11 which is your solution for how many students had 3 or more absences.

If you are solving for the question in the picture your answer would be 18. Whiich is letter A.
12x+15y=390 Original Equation
12(10)+15y=390 Replace x with 10
120 + 15y= 390 Mutiply 12 by 10
-120 = -120 subtract 120 on both sides to simplfy the equation
15y= 270 New equation
÷15 = ÷15 To get the variable alone divide 15 on both sides
y=18 Your value for y.
X can be anything you want as long as it is not 1 or -7. If you have repeated x values with different y values, then it won't be a function.
Solution-
∵ she earns $50 per day and she worked 30 days in the quarter.
∴ Her total earning for this period = $(50×30) = $1500.
Also she earns 3% commission for her sales.
∴ Her total earning by commission =3% of $4596= $ (3×4596)/100
= $ 137.88
∴Total amount earned by Paige= $137.88+$1500
=$ 1637.88
