Answer: 6 hours
Explanation: You divide 330 miles by 55 mph.
X=number of books that cost 0.60
y=number of books that cost 0.75
x+y=16
0.6x+0.75y=10.95
solve
multiply second equation by 10 for nicity
6x+7.5y=109.5
multiply first equesiotn by -6 and add to second
-6x-6y=-96
<u>6x+7.5y=109.5 +</u>
0x+1.5y=13.5
1.5y=13.5
divide both sides by 1.5
y=9
sub back
x+y=16
x+9=16
minus 6
x=7
seven 0.60 books and nine 0.75 books
Answer:
5 or 1
Step-by-step explanation:
|x-3| = 2
x-3 = 2 or -2
x = 5 or 1
We are given
Tobias dropped a tennis ball from a height of 60 meters. The time in seconds it takes for the ball to fall 60 feet is 0.25(radical60).
so, time is
we have to approximate it's value
First approximation set:
we know that
we can take sqrt all the sides
we can simplify it
Divide all sides by 4
Second approximation set:
Divide all sides by 4
Third approximation set:
Divide all sides by 4
so, we get
