Place value is the value each digit has in its position: in order from higher to lower value, there is thousands, hundreds, tens, and ones.
When you divide by 10, you are moving (only once) every digit from its present place value to the right.
For example 6430 : 10= 643, you have moved every digit to the right, making the zero disappear (or better yet, separated by a hidden and in this case useless comma).

In the table below, x represents the miles traveled and y represents the cost to travel by train.
Afina-wow [57]

Answer:

Third option

m = 2.25

Step-by-step explanation:

The slope of the function is equal to its rate of change between two points.

For example, for a couple of points (x_1, y_1),\ (x_2, y_2)

The slope is:

m =\frac{y_2-y_1}{x_2-x_1}

In this problem we have the following points

1.(2, 8.50) , 2. (5, 15.25), 3. (8, 22.00) , 4. (12, 31.00)

We calculate the slope between the first two points

m =\frac{15.25-8.50}{5-2}=2.25

We calculate the slope between the points 3 and 4

m =\frac{31-22}{8-4}=2.25

We calculate the slope between the points 2 and 3

m =\frac{22-15.25}{8-5}=2.25

The slope is always the same. Therefore m is constant and the fution is a line of slope m = 2.25

At a butcher​ shop, Hilda bought 6 1/4 lb of Beef and some pork. She left with 13 1/20 lb of meat. Express the number of pounds
lina2011 [118]

Hilda bought 15.11 lb of pork.

Step-by-step explanation:

Cost of Beef that Hilda bought = 4 17/20 = 4.85 lb

Cost of the total meat she bought = 19 24/25 = 19.96 lb.

To find the number of pounds of pork she bought, subtract.

Number of pounds of pork she bought = 19.96 - 4.85 = 15.11 lb.
