Money earned: 8*4 = $32
Tips needed: 100-32 = $68
If he keeps 90%, the total money he needs to earn in tips is (10/9)*68 = $75.55
X+x+1+x+2+x+3=50
4x+6=50/-6
4x=50-6=44
x=44:4=11
⇒The 1st number is 11, the 2nd is 12, the 3rd is 13 and the 4th is 14.

Answer:
none
Step-by-step explanation:
y = -4x^2 +3x-2
To find the x intercepts, let y =0
0 = -4x^2 +3x-2
Using the discriminant
a=-4, b=3 c=-2
b^2 -4ac
3^2 -4(-4)(-2)
9 -32
-23
Since this is negative all the roots are complex, so it has no real roots
none
