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>

Answer:
x = 10
Step-by-step explanation:
Given question is incomplete; here is the complete question.
A man (M) is standing halfway between a tree (T) and a lamppost (L). What is the value of x.
TM = (2x + 8)
ML = (3x - 2)
Since, a man M is standing halfway between a tree and a lamppost,
measure of TM = measure of ML
(2x + 8) = (3x - 2)
3x - 2x = 8 + 2
x = 10
Therefore, x = 10 will be the answer.
Answer:
4b
Step-by-step explanation:
The GCF is the largest number that will multiply into each term. It can be both numbers and letters.
12b = 2*2*3*b and 40b^4 = 2*2*2*5*b*b*b*b has GCF 2*2*b = 4b
