Answer:
x=3
Step-by-step explanation:
This is a proportional equation:
Given: x/9=9/27
Cross-multiply: 27x=81
Divide: x=3
So x=3
8y-9-4y+5=12y-4-5y
4y-4= 7y-4
Add 4 to both sides
4y=7y. The only answer is 0
Answer:
x = 5/3
Step-by-step explanation:
3x = xy - 55
3x = x*6 - 5
3x = 6x - 5
3x = 5
x = 5/3
Step-by-step explanation:
i believe the answer is y=24
No, -Cos(120) is equal to 5, while Cos(-120) is equal to -5.
Hopefully this helps!
