We are asked about the fraction of pizza each student
gets, so the relevant numbers here is only 14 students and 7 pizzas. SO the
fraction of pizza each student get is the ratio of the two:
fraction = 7 pizzas / 14 students
fraction = 1 / 2
<span>So each student gets 1/2</span>
1. |b/5|=1 take the equation out of the absolute value
b/5=1
*5 *5 multiply both sides by 5
_____
b=5
2. 2-5|5m-5|=-73 get rid of what's outside the absolute value first
-2 -2 subtract 2 from both sides
____________
-5|5m-5|=-75
÷-5 ÷-5 divide both sides by -5
__________
|5m-5|=15 take the equation out of the absolute value
5m-5=15
+5 +5 add 5 to both sides
_______
5m=20
÷5 ÷5 divide both sides by 5
_____
m=4
3. |7p+4|/8=3
*8 *8 multiply by 8
__________
|7p+4|=25 take out the equation
7p+4=25
-4 -4 subtract 4
_______
7p=20
÷7 ÷7 divide by 7
______
p=20/7
4. 5-8|-2n|=-80
+5 +5 add 5
__________
-8|-2n|=-80
÷-8 ÷-8 divide by -8
________
|-2n|=10 take out equation
-2n=10
÷-2 ÷-2 divide by -2
______
n=-5
