Luis used compensation to find 6,572-239 compensation methods u

Here is the solution...

Compensation

The compensation is nothing but the process of reforming the given expression to find the answer mentally.

Here we need to rewrite the given expression in order find the answer mentally.

Step 1:

Here we can add 8 with 6572, so we get 6580.

Step 2:

Add 8 from 239, so we get 247.

Step 3:

We can rewrite 247 as 240 + 7

Step 4:

Now we can subtract 240 from 6580, so we get 6340.

We can calculate this mentally.

Step 5:

Finally, we can subtract 7 from 6340 mentally, So we get

6333.

Mathematically, the above expression written as

6572- 239

= 6572 + 8 - (239 + 8)

= 6580 - 247

= 6580 - (240 + 7)

= 6580 -240  - 7

= 6340 - 7

= 6333

step-by-step explanation:

hello and welcome!

so, when we see the words "proportional" along with a table, we need to know that we're looking numbers that divide by the same thing.

looking at this table, we simply have to do a trial and error, and divide to see which numbers have the same quotient. if you look at choice a & c, they both have equal quotients for three of the numbers, with one exception, so those can't be the answer. looking at b, there is no similarity, so that can't be it. then, we see d; if you divide all the numbers in the table, you'll see that they all divide by two, which is a proportional relationship, and our answer!

also, always remember that the x will always be the number that goes into y, and somewhere behind this table, is a formula. for this specific table, the formula would be:

since our x-value is being divided by two to get the y-value. and if they were to ask for more numbers in the series, this is the formula you would use to find them.
