The number 939,515 rounded to the nearest tens is 939520.
We round off numbers to make them easier to remember and it also keeps their value approximately to the place it has been rounded off.
To round off any number to any place we'll look for the digit next to that place and if it is equal to or greater than 5 we'll add one to the previous digit and make all the digits after it zeroes and if the digit is less than 5 we do not add one to the preceding digit and simply make all the digit after it to zeroes.
Given, A number 939515 and we have to round it to the nearest ten.
To round this number to the nearest ten we'll look at the digit at the unit's place.
The digit at the unit place is 5 so we'll add 1 to the tens digit and make the unit digit zero.
Therefore the number 939515 rounded to the nearest tens place is
939520.

Charles paid $8.70 of the bill.
The first way we can find this is:
= Proportion that Charles paid for x Cost of pizza
= 3/5 x 14.50
= 43.5 / 5
= $8.70
The second way is:
= Cost of Pizza - Proportion that others paid for
= 14.50 - ( (1 - 3/5) x 14.50)
= 14.50 - ( 2/5 x 14.50)
= 14.50 - 5.80
= $8.70
In conclusion, Charles paid $8.70 out of the total bill for the pizza.

The point (x, -3) is a solution to the equation shown. What is the value of x?
Answer:
x = 1
Step-by-step explanation:
Given
- 4y + 5x = 17 and (x - 3) is a solution
Substitute y = - 3 into the equation and solve for x
- 4(- 3) + 5x = 17
12 + 5x = 17 ( subtract 12 from both sides )
5x = 5 ( divide both sides by 5 )
x = 1
Solution is (1, - 3 )
Answer:
x = 1
Step-by-step explanation:
Add the ratio: 8 + 12 =20
Divide total bike by that: 100/20 = 5
Multiply each part of the ratio by that:
8 x5 = 40
12 x 5 = 60
40 bikes are purple
60 bikes are red
Answer: 40
Step-by-step explanation:
Purple:Red = 8:12
Purple bikes = 8/20 x 100 = 40
