FALSE
Answer:
Mark C.
Step-by-step explanation:
If there are 27 students in both classes, it's logicial to multiply both classes by two to get the total students.
Since the <em>S</em> stands for the students absent, that should come after the brackets.
You would divide both 12 and 7n by 7. To isolate the variable. You end up with 5+n. You can not say 5n because you cannot combine unlike terms. Your answer would be 5+n. Hope this helps
Answer:
![-7+5[(-5)^2+(-32)]=-42](https://tex.z-dn.net/?f=-7%2B5%5B%28-5%29%5E2%2B%28-32%29%5D%3D-42)
Step-by-step explanation:
First solve the sums that are within the parentheses.
Remember that if the numbers have equal signs then they are added and the same sign is placed.
If the numbers have different signs they are subtracted and the sign of the major is placed
So:


Then we have the following expression:
![-7+5[(-5)^2+(-32)]](https://tex.z-dn.net/?f=-7%2B5%5B%28-5%29%5E2%2B%28-32%29%5D)
Remember that by multiplying signs you get:
(+) * (+) = +
(-) * (-) = +
(+) * (-) = -
(-) * (+) = -
Then:
![-7+5[(-5)^2+(-32)]=-7+5[(-5)*(-5) -32]](https://tex.z-dn.net/?f=-7%2B5%5B%28-5%29%5E2%2B%28-32%29%5D%3D-7%2B5%5B%28-5%29%2A%28-5%29%20-32%5D)
![-7+5[(-5)^2+(-32)]=-7+5[25 -32]](https://tex.z-dn.net/?f=-7%2B5%5B%28-5%29%5E2%2B%28-32%29%5D%3D-7%2B5%5B25%20-32%5D)
![-7+5[(-5)^2+(-32)]=-7+5[-7]](https://tex.z-dn.net/?f=-7%2B5%5B%28-5%29%5E2%2B%28-32%29%5D%3D-7%2B5%5B-7%5D)
![-7+5[(-5)^2+(-32)]=-7-35](https://tex.z-dn.net/?f=-7%2B5%5B%28-5%29%5E2%2B%28-32%29%5D%3D-7-35)
![-7+5[(-5)^2+(-32)]=-42](https://tex.z-dn.net/?f=-7%2B5%5B%28-5%29%5E2%2B%28-32%29%5D%3D-42)
