How does understanding place value help you to subtract across zeros

Mathematics
1 answer:
Lorico [155]3 years ago

I'm not sure what you mean by "across zeros" but knowing your place value helps you a lot. For example:
"What is the value of 6 in the number 2,650?"
You would say,
"The value of 6 in the number 2,650 is 600, because it is in the hundred's place."
Make sure you say hundreds and not hundredth's, because the hundredths is behind a decimal. Hope this helped! :)

Answer:

Mr.Walters car can go 15 miles on one gallon of gas.

Step-by-step explanation:

To find this, you first want to put it into a ratio.

480:32

Next, you want to divide.

480/32

After you divide, you get 15. That tells you that you get 15 miles off of one gallon of gas.

Type the correct answer in each box.<br><br> The value of x is °, and the value of y is <br> °.
Solnce55 [7]

Answer:

<h2>x = 60°, y = 50°</h2>

Step-by-step explanation:

We know: the angles measures in a triangle add up to 180°.

<em>(look at the picture)</em>

z + 50 + 60 = 180

z + 110 = 180    <em>subtract 110 from both sides</em>

z = 70°

x + 50 + 70 = 180

x + 120 = 180         <em>subtract 120 from both sides</em>

x = 60°

Angles x, y and z are on one side of a straight line. Therefore they add to 180°.

x + y + z = 180

60 + y + 70 = 180

y + 130 = 180         <em>subtract 130 from both sides</em>

y = 50°
