M= 276 31+276=307.
307-31=276 that’s how I found M
Answer:33/9
Step-by-step explanation:
Log10(x+3)-Log10(x-3)=1
Log10((x+3)/(x-3))=1
(x+3)/(x-3)=10^1
(x+3)/(x-3)=10
Cross multiply
x+3=10(x-3)
Open brackets
x+3=10x-30
Collect like terms
10x-x=30+3
9x=33
Divide both sides by 9
9x/9=33/9
x=33/9
So first, i like to answer the question first. 17 times 6 = 102. So you can use 1 100 model/block and 2 ones :)
Yes it is the same. 1/4 +1/4 = 1/2. so 9/10-1/2=9/10-1/2
