Step-by-step explanation:
Given the expression that represents the situation where Alex and Janet have read the same number of books as
4m = m-1
where m represents the number of months Janet has been reading books,
To calculate m
STEP 1: subtract m from both sides
4m - m = -1
3m = -1
Step2; divide both sides by 3
3m/3 = -1/3
m = -1/3
Hence the value of m is -1/3
The most common way to raise the pH of soil is to add pulverized limestone to the soil. Limestone acts as a soil acid neutralizer and consists of either calcium and magnesium carbonate or calcium carbonate. These are called dolomitic limestone and calcitic limestone respectively.
