Answer:

The correct option is:

B. u + 2b = 30

Step-by-step explanation:

The owner of a bike shop sells unicycles and bicycles and keeps inventory by counting seats and wheels. One day, she counts 21 seats and 30 wheels.

u is the number of unicycles and b is the number of bicycles.

There are total 21 seats

⇒  u+b=21

unicycle has 1 wheel and bicycle has 2 and total there are 30 wheels

⇒ u+2b=30

Hence, the correct option is:

B. u + 2b = 30

The wheels function is:

w=2b+u and w=30 so

u+2b=30

Which is greater, 4.87 x 10^9 or 9.212 x 10^8? <br> please helpp
STatiana [176]

Answer: 4.87 x 10^9  is greater than 9.212 *10^8

Step-by-step explanation:

4.87 x 10^9  is greater than 9.212 *10^8 because it has the greater exponent.

4.87 * 10^9 =  4,870,000,000

9.212 *10^8= 921,200,000

4,870,000,000 > 921,200,000

How do i solve this ? :')
Vesna [10]
I think you are supposed to make the fraction equivalent so you know that 27/9 is 3, so you would do the same thing whatever number is supossed to be under 17 needs to equal to 2 when divided by 9. So you should probably know that 3 * 9 is 18 so x needs to be a number that when subtracted by 5 gives you 18. So x=23. Hope this is right and it helps!

Some examples of additions with integers with 5 terms or more are:

  • 20 + 1 + 1 + 2 + 1= 25
  • 2 + 1 + 1 + 2 + 1= 7
  • 20 + 2 + 1 + 2 + 1= 26
  • 20 + 1 + 1 + 3 + 1= 26
  • 20 + 1 + 1 + 4 + 1= 27
  • 200 + 1 + 1 + 2 + 1= 205

<h3>What is an Integer?</h3>

In mathematics, an integer is a whole number that is used to represent a value and is not a fraction.

Furthermore, we can make the addition of integers as they would increment based on the number they are being incremented with and this has been shown above.
