Answer:
-17
Step-by-step explanation:
- 5 * (6 + 4) ÷ 2
Following PEMDAS, we must focus on the parenthesis first.
- 5 * (6 + 4) ÷ 2
- 5 * (10) ÷ 2
Now we will focus on the exponent:
- 5 * 10 ÷ 2
8 - 5 * 10 ÷ 2
Now Multiplication/Division.
This is where you must follow the order in the equation where you see the multiplication sign first, so you multiply first.
8 - 5 * 10 ÷ 2
8 - 50 ÷ 2
Next, Divide:
8 - 50 ÷ 2
8 - 25
Subtract:
8 - 25
-17
- 5 * (6 + 4) ÷ 2 = -17.
Answer:
-60p - 1
Step-by-step explanation:
Distribute the parenthesis then add like terms together.
Step 1: Distribute
6 -60p - 7
Step 2: Combine like terms
-60p - 1
108 27
------ < 8, or 108 < 8x, or (108/8) < x, or x > -----
x 2
-7 replaces the t so it would be
w(-7) = -2(-7)+1
= 14+1
= 15
Answer: Option 'B' is correct.
Step-by-step explanation:
Let the initial concentration be
Let concentration after t= 90 hours be N
Since we have given that Sodium-24 has a half life of 15 hours i.e.
So, According to question,
As we know that
Hence, Option 'B' is correct.
