Answer:
First question -> y = 2
Second question -> y = 10
Step-by-step explanation:
<u>Step 1: Solve y + 2 = 4</u>
Subtract 2 from both sides
y + 2 - 2 = 4 - 2
<em>y = 2</em>
<em />
<u>Step 2: Solve y - 2 = 8</u>
Add 2 to both sides
y - 2 + 2 = 8 + 2
<em>y = 10</em>
<em />
Answer: First question -> y = 2
Second question -> y = 10
Answer:
30 = 2 x 3 x 5
Step-by-step explanation:
The secret number is the least whole number that has three different prime factors. Since, this is the least whole number it should have the 3 smallest prime numbers as its factors.
The 3 smallest prime numbers are: 2, 3 and 5
The number that will have 2, 3 and 5 as its only factors will be the least whole number with 3 different prime factors.
So, the secret number must be = 2 x 3 x 5 = 30
Answer:
A
Step-by-step explanation:
Factor out each equation
(x+4)(x-4)/2(x+4) x(x-1)(x-1)/(x-1)(x+4)
cancel out the similar ones.
leaving you with x(x-4)(x-1)/2(x+4)
I think the answer would be 16
The answer is 10
