Answer:
Ok, she walks 3 miles to and from the library.
So in total, she walks 3 miles two times, then in one week, she walks 2*3mi = 6miles.
She says that she walked about 300 miles in total.
We must see if 300 miles is a multiple of 6 miles.
300mi/6mi = 50.
This means that she would walk about 300 miles since she started counting if she went to the library and back home exactly 50 times (again, since she started counting).
And she does this once a week, then if she started counting 50 weeks ago, then it is possible,
Hello! And thank you for your question!
To get a improper fraction:
times the denominator by the whole number. Then add the numerator.
5*5=25+4=29.
Final Answer:
29/5
-2x^2 + 3x - 9 = 0
The quadratic is not factorable so quadratic formula must be used.
x = (-b + - √(b^2 - 4ac))/2a
a = -2, b = 3, c = -9
x = (-3 + - √(9 - 4*-2*-9))/-4
x = (-3 + - √(-63))/-4
x = -3 + - 3i√7
--------------
-4
x = 3 + 3i√7 x = 3 - 3i√7
------------ ------------

Answer:
x=55
a=11.47
Step-by-step explanation:
To find x we add all the angles in the triangle. The three angles in a triangle add to 180 degrees
35+x+90 = 180
Combine like terms
125+x=180
Subtract 125 from each side
125-125+x=180-125
x= 55
To find a
sin 35 = opposite side/ hypotenuse
sin 35 =a/20
Multiply each side by 20
20sin35 =a
11.47152873 =a
Add them up and divide by 4 and it says round up. your answer is B
