Answer:
-40
Step-by-step explanation:
-|-5|-|-7-28| The given equation.
-|-5|-|-35| The absolute value "|" sign is just like the parenthesis.
-5-35 "Convert" the numbers in between the absolute value signs to positive numbers because the absolute value means how many values away from zero. It cannot be a negative.

Answer:
6
Step-by-step explanation:
you want to create two equations for each situation so if v=number of students that can fit in a van and c=number of students that can fit in a car then you can create the equations 3v+1c=22 and 2v+4c=28
then you want to make both equations equal to c
so for the first one you subtract both sides by 3v and you get c= -3v+22
and for the second one you subtract 2v from both sides and end up with 4c=-2v+28 and then divide both sides by 4 leaving you with c= -1/2v+7
then you make both of those equations equal to each other and solve for v
so -3v+22= -1/2v+7 and you end up with v=6
therefore, each van can hold 6 students
The answer is 2 = p
Explanation: Here the goal is to get the variable "p" by itself, so first your have to distribute 2 to (p-12) which gives you -10p = 2p-24. Then you add 10p on both sides so that the variable is on one side. Then you add 24 to both sides. After that you divide 12 from both sides, giving you 2 = P
-10P = 2(p-12)
-10p = 2p-24
+10p +10p
0 = 12p-24
+24 +24
24 = 12p
24÷12 = 12p÷12
2 = p
