Answer:
last test grade=x x ≥ 79 so 79%
Step-by-step explanation:
(84/5)+(88/5)+(95/5)+(104/5)+(x/5) ≥ 90
Simplify: (371/5)+(x/5) ≥ 90
Subtract (371/5) from both sides
Then you have (x/5) ≥ (79/5)
Then multiply both sides by 5 and you have x ≥ 79

Answer: x=0.5, y=1
Step-by-step explanation:
-4x+3y=1
6x-y=2
6x-2=y
-4x+3(6x-2)=1
-4x+18x-6=1
-4x+18x=7
14x=7
x=0.5
6x-y=2
6(0.5)-y=2
3-y=2
y=1
