So, because he used a five dollar certificate, the total price of his meal was 7.36. Now we need to find the price of his food. Because he gave the waiters a fifteen percent tip, his meal is 85% of the total cost:
0.85(7.36) = 6.256
We can round up:
PETER SPENT $6.26 ON HIS MEAL
Answer: 0
Step-by-step explanation:
The disciminant \Delta tells you how many real solutions a quadratic equation has, depending on its sign:
\Delta>0\implies\text{2 solutions}\\\Delta=0\implies\text{1 solution}\\\Delta<0\implies\text{no solutions}
Step-by-step explanation:
SE RESTAN ENTRE LOS NÚMEROS QUE TIENEN LA MISMA VARIAVLE.
- (8x - 16x) + (9 + 9) = 
- 24x + 18
first you will need to find his speed = 0.4 mph (that's really slow, idk if i was wrong)
next up, it will take him about: 40 ÷ 0.4 = 100 hours for him to drive 40 miles
Answer:
a. 125
Step-by-step explanation:
the angle labeled "x" is supplementary with the angle that has a measure of 55°
Supplementary angles add up to equal 180°
This means that x + 55 must equal 180
Note that we've just created an equation that we can use to solve for x.
We now solve for x using the equation we just created.
x + 55 = 180
subtract 55 from both sides
x = 125
The answer is a
