-3(4r -8)=-36 the answer is r=5
<span>Label the place value 12 354.897
=> the given numbers are mixed number. We have the whole number which is 12
354 and the decimals which id 897.
Now, Let us label each digit’s place values:
1 – ten thousands = equals to 10 000
2 – thousands = equals to 2 000
3 – hundreds = equals to 300
5 – tens = equals to 50
4 – ones = equals to 4
.8 – tenths = equals to 8/10
.09 – hundreds = equals to 9/100
.007 – thousands = equals to 7/1 000</span>
The answer would be:
8 × 4 = 32
32 ÷ 4 = 8
Answer: 7
Add up the values to get 4+10 = 14
Then divide that result over 2 to get 14/2 = 7
This is using the midpoint formula.
