Answer:
There are 40 books total
Step-by-step explanation:
you need to set a proportion
The first fraction is 55/100 it's over 100 because it's percent
the other fraction is 22/x the 22 is out of a total number so that's why it's on top and x because you don't know the total number of books
then you multiply diagonally
55×x= 22×100
55x=2,200
Then you solve it like a regular equation by dividing both sides by 55
x=40
Answer:
The initial cash balance in bank is $46
Step-by-step explanation:
The equation given to determine b which is the initial money before she withdrew $60 is
b + (-60) = -14
Let's solve for the value of b which is the initial balance of the money in the bank.
b + (-60) = -14
b -60 = -14
b = -14+60
b = 60-14
b = 46
The initial money before she withdrew $60 was $46

Answer:
In the case of the equilateral triangle, , the exterior angle, plus 60 equals 180. Subtracting 60 from both sides of this equation gives us a value of equal to 120. This means that the exterior angle of an equilateral triangle is equal to 120 degrees. The sum of all the exterior angles is always 360 degrees.
