Answer: 15 pounds per inches
Step-by-step explanation:
P1V1 = P2V2
12 ppi × 5L = P2 × 4L
P2 = 12 ppi × 5L / 4L
P2 = 12 ppi × 5 / 4 ( L in denominator is cancelled by L in numerator)
P2 = 3 ppi × 5 ( 12 is cancelled by 4 in denominator)
P2 = 15 ppi
x ^ 2 - 18 = 0
For this case, the first thing you should do is rewrite the expression:
x ^ 2 - 18 = 0
x ^ 2 = 18
The solutions for this case are:
x1 = root (18)
x2 = -raiz (18)
Therefore the answer is:
2 solutions of real numbers.
Answer:
2
Answer:
a. She ran 7 days
b. 5 miles
Step-by-step explanation:
a. The line plot shows how many miles Katrina ran last week not days however on the line plot there are 7 x's on it, if she ran once a day, then she ran 7 days last week
b. I'm not sure which equation that you would use but I done something similar to this:
1/4 + 1/2(2) + 3/4 + 1(3)=5
[] The domain is the set of x -coordinates, so in this case, we will take the three x values.
-> These are -1, 4, 4, and 1
<u>Answer</u>
[] The first option - {-1, 1, 4}
Have a nice day!
