Answer:
She subtracted 3.4 on the left and added 3.40 on the right
Step-by-step explanation:
3.40 + 0.85 x = 5.27
Subtract 3.40 from each side
3.40 -3.40+ 0.85 x = 5.27-3.40
.85x = 5.27 - 3.40
.85x =1.87
Divide by .85
.85x/.85 =1.87/.85
x = 2.2

Answer:
Step-by-step explanation:
This is the concept of algebra. Given that Holly has 30 pencils, the total number of pencils that Holly remained with after she gave her friends 6 pencils are:
Total=30-6=24 pencils
The fraction of pencils that need to be sharpened is 3/8
The number of pencils represented by this fraction will be:
(fraction of un-sharpened pencils)×(total number of remaining pencils)
3/8×24
=9 pencils
therefore we conclude that 9 pencils are not sharpened.
