Answer:
False
Step-by-step explanation:
The coefficients (numbers in front) don't matter, but the exponents do.
Like terms have exactly the same exponents on the same variables.
are not like terms.
Example: 
<u>are</u> like terms--same exponents on the x's, same exponents on the y's.
Answer:
The answer is 198.
Step-by-step explanation:
First you need to know how much is a batch of cookies which is 60. Since she made 3 batches that means you will need to multiply 3 by 60, which will give you 180 cookies. Next you will need to add 2 to 10 because thats how much were took. That equals 12. Subtract 12 from 180 and that will give you 168. Last but not least you will need to add 30 because that is half the batch of cookies her neighbor gave to her. So 168 plus 30 equals 198.
Answer:
50 coins
Step-by-step explanation:
We are given £1 worth of 20p coins.
Since it is known that,
£1 = 100p
i.e. £10 = 100 ×10 p = 1000p
As, we are taking 20p coins to get make the sum 1000p.
Thus, the number of 20p coins will be 
i.e. 50 coins
Hence, we get 50 coins to make £10 worth 20p coins.
Answer:
x = -3
Step-by-step explanation:
5(x-2)+3x-4 = -38
=> 5x-10+3x-4 = -38
=> 5x+3x-10-4 = -38
=> 8x-14 = -38
=> 8x = -38+14
=> 8x = -24
=> x = -24/8
=> x = -3
