Answer:
you should be able to do this
Step-by-step explanation:
6x²-5x-4=0
x=(-b+/√b²-4ac)/2a
D=b²-4ac=25+4*6*4=121, √D=√121=11
x=(5+/-11)/12
x1=-6/12=-1/2
x2=16/12=4/3
Answer:
55
Step-by-step explanation:
3x - 60 = x + 50
3x = x + 50 + 60
3x = x + 110
3x - x = 110
2x = 110
110 / 2 = 55
Hello,
To solve this, we should first write an inequality.
Since we have to pay $109.50 to rent the studio, we will start with that.
Then, we add on 15 per person. Finally, it needs to be under $319.
The inequality is:
109.5 + 15x < 318
Solve it gives:
15x < 208.5
x < 13.9
We have to invite less than 13.9 people. So they most we can invite is only 13.
I hope this helps,
MrEQ
