8x+4=9x-5
when you solve that out you get x =9
then you plug in x everywhere in the chart
3(9)=27
9(9)-5=76
180-76-27= 77°
angle E =77°
please mark brainiest if you can
Answer:
no solutions
Step-by-step explanation:
3(-n+4)+5n=2n
Distribute
-3n +12 +5n = 2n
2n+12 = 2n
Subtract 2n from each side
12 = 0
This is never true so there are no solutions
X = 5y (*2) because there are four total sides
2x = 10y
so plug in y in the equation
60 = 10y + 2y
60 = 12y
5 = y
x = 5(5)
x = 25
So the length is 25 units, and the width is 5 units
Answer:
1) x≥6

2) h > 20
Mark worked more than 20 hours.
Step-by-step explanation:
1) -20x+18≥-102
-20x≥-102-18
-20x≥-120
Dividing -20 both side
≥![\frac{-120}{-20}](https://tex.z-dn.net/?f=%5Cfrac%7B-120%7D%7B-20%7D)
x≥6
--------------------------------------
--------------------------------------
2) 14h + 25 > 305
14h > 305-25
14h > 280
Dividing 14 both side
![\frac{14}{14}h > \frac{280}{14}](https://tex.z-dn.net/?f=%5Cfrac%7B14%7D%7B14%7Dh%20%3E%20%5Cfrac%7B280%7D%7B14%7D)
h > 20
Mark worked more than 20 hours.
