Answer:
<h2>The number of the books is 4384.</h2>
Step-by-step explanation:
Let, the number of the books will be x.
With the first method, the total cost will be, $(19521 + 21x) and with the second method, the total cost will be $(62265 + 11.25x).
As per the given condition it is told that the costing should be equal.
Hence, 
.
Answer:
Step-by-step explanation:
Hey there, 100/5=20, 20/4=5. 4*5=20, 20*5=100. Now, 4*5*5=100. Therefore, the number that goes in the box to make the number sentence true is 5.
Answer:
8.0023x 10^4
Step-by-step explanation:
80023
to get to the first place number you have to move the decimal 4 times and if it looked like this .80023 it would be 10^-1 going down moving places back wards
Well lets start by getting y. We already know that all angles of a triangle will equal 180 degrees.
Therefore we know that 65 + 65 + y = 180. To solve for y we just add the two 65's then subtract that from 180
y = 180-130 = 50 Therefore y = 50
Now lets solve for x. We know that since angle B is flat it is equal to 180. The unknown value of angle B = 180 - 65
Therefore that unknown value = 115
As we previously stated all angles of a triangle equal 180. We can now come up with this equation: 115 + x + x = 180
2x = 65
x = 32.5
