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.
Answer is A because it’s just is
20/24-(-18/24)=38/24
Subtracting a negative is adding a positive.
20/24+18/38
38/24
24 goes into 38 once and 14/24 is left over.
1 14/24
Divide the fraction by two for simplest form.
1 7/12
Answer:
The answer to your question is below
Step-by-step explanation:
First way
20 = 5(-3 + x) expand
20 = -15 + 5x simplify like terms
5x = 20 + 15
5x = 35 divide both sides by 5
5x/5 = 35/5
x = 7
Second way
20/5 = 5/5 (-3 + x) Divide both sides by 5
4 = -3 + x Add +3 in both sides
4 + 3 = -3 + 3 + x Simplify like terms
7 = x
