Draw or write to explain why 1 hundred 4tens and 14 tens name the same amount.

We have to explain that  1 hundred 4 tens and 14 tens name the same amount.

Consider 1 hundred 4 tens

Since, 1 hundred = 100

It can also be expressed as " 100 = 10 tens"

So, 1 hundred = 10 tens

Now, 1 hundred 4 tens = 1 hundred + 4 tens

= 10 tens + 4 tens

= 14 tens

=

= 140

Consider 14 tens

=

= 140

Therefore, 1 hundred 4 tens and 14 tens represents 140, so it represents the same amount.

x + y = 90 5x – 10y = 90 90 – 10y = 5x 90 + 10y = 5x

step-by-step explanation:

last month maria hiked the 5-mile mountain trail a number of times and she hiked the 10-mile canal trail several times. let x represent the number of times she hiked the 5-mile trail, and let y represent the number of times she hiked the 10-mile trail. if she hiked a total of 90 miles, which equation can be used to find the number of times maria hiked each trail? x + y = 90 5x – 10y = 90 90 – 10y = 5x 90 + 10y = 5x
