Sarah has three more than four times the money that Jessica has. Together they have $72. How
hoa [83]

Answer:

Jessica has $13,80 and Sarah has $58.20.

Step-by-step explanation:

Let j be the amount of money that Jessica has.

Let s be the amount of money that Sarah has.

s + j = 72

Since Sarah has 3 more than 4 times what Jessica has...

s = 4j + 3

So 4j + 3 + j = 72

5j = 69

j = 13.8

So Jessica has $13,80.

Therefore Sarah has $58.20.

Luis used compensation to find 6,572-239 compensation methods u
saveliy_v [14]

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.

<u>Step 1:</u>

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

<u>Step 2: </u>

Add 8 from 239, so we get 247.

<u>Step 3:</u>

We can rewrite 247 as 240 + 7

<u>Step 4:</u>

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

We can calculate this mentally.

<u>Step 5:</u>

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
