When you multiply/divide by a negative number while solving the inequality, you reverse the symbol.
A.) 4(5 - y) ≥ 80 To solve this, isolate/get the variable "y" by itself in the inequality. Divide 4 on both sides
![\frac{4(5-y)}{4} \geq \frac{80}{4}](https://tex.z-dn.net/?f=%5Cfrac%7B4%285-y%29%7D%7B4%7D%20%5Cgeq%20%5Cfrac%7B80%7D%7B4%7D)
5 - y ≥ 20 Subtract 5 on both sides
5 - 5 - y ≥ 20 - 5
-y ≥ 15 Divide -1 on both sides to get "y" by itself
Because you are dividing by a negative number, you need to reverse the sign
y ≤ -15
B.) 2(y - 3) ≥ 8 Isolate "y", divide 2 on both sides
y - 3 ≥ 4 Add 3 on both sides to get "y" by itself
y ≥ 7
C.) 3y - 4 > 1 Add 4 on both sides
3y > 1 Divide 3 on both sides to get "y" by itself
![y>\frac{1}{3}](https://tex.z-dn.net/?f=y%3E%5Cfrac%7B1%7D%7B3%7D)
D.)
Isolate "y", add 3/4 on both sides
6y > 1 Divide 6 on both sides to get "y" by itseld
![y>\frac{1}{6}](https://tex.z-dn.net/?f=y%3E%5Cfrac%7B1%7D%7B6%7D)
I dont know what grade are you in
Answer:
uh this question is incomplete
Step-by-step explanation:
X+x+2x+2x=6x
360 is total divide by 6 for x
360/6=x
X=60
X2=60*2=120
