Answer:
-2 +/- [(sqrt 88)/ 4]
or
0.35, -4.35 to the nearest hundredth.
Step-by-step explanation:
2x^2 + 8x - 3 = 0
Using the quadratic formula:
x = [ -8 +/- sqrt (8^2 - 4*2*-3) ] / 4
= -2 +/- (sqrt 88)/ 4
Answer:
$1161
Step-by-step explanation:
21.5% of 5400 is 1161.
If the total bill is $85, and you want to leave a 15% tip, then you can calculate it as follows:
85 * 15%
= 85 * 15/100
= 85 * 0.15
= 12.75
The amount that should be left as a tip is D. $12.75.
1) Let's solve for x, writing this equation.
3x +8*59 =0
3x +472=0 <em>Subtract 472 from both sides</em>
3x = -472
x= -472/3 or -157.33
2) So the answer is x= -472/3
