Answer:
B
Step-by-step explanation:
18 = 2 * 3 * 3 = 2 *3²
Hint:
Let me tell you....
This equation cannot be solved at all.
Why?
3(n+5)≥3n+8
3n+15 ≥ 3n+8
3n-3n ≥ 8-15
0 ≥ -7
Even though it make sense than 0 ≥ -7... But since 'n' disappeared, this means that this equation have no solution. To solve means to find the value of 'n' and if there is no 'n' since 3n-3n=0, there is no solutions.
This question is pretty much invalid.
Extra:
To tackle such inequality qns:
Step 1: Expand the brackets
Step 2: Move the term to one side of the equations
and constant to another side of the equation.
Step 3: Find the value of the term. Done.
The value of 6 is a Rational number
Answer:
Lin has 11 acorns ⇒ answer D
He subtract 4 from 7 instead of add 4 to 7
Step-by-step explanation:
- Lin has 4 pinecones and some acorns
- She has 7 fewer pinecones than acorns
- The meaning of 7 fewer pinecones than acorns is the number of the
pinecones is less than the number of acorns by 7
∵ She has 4 pinecones
∵ She has 7 fewer pinecones than acorns
- The number of pine cones is less than the number of acorns by 7
∴ 4 = number of acorns - 7
- Add 7 to both sides
∴ 11 = number of acorns
*<em> Lin has 11 acorns</em>
- Tom choose answer A which is 3
- He made a mistake in the equation
- He put ⇒ number of the acorns = 7 - 4 not 7 + 4
∴ number of acorns = 3
* <em>He subtract 4 from 7 instead of add 4 to 7</em>
