               11x-8

2) (2-x)-3(6 + 8x)-12 
distribute the negative sign and the -3 
-2 + x - 18 - 24x - 12 

then you have to combine like terms 
-23x - 32

3) 11-(3x-6)+2(4x+5)-x 

11-(3x-6)+8x+10x 

11-3x+8x+10x 
11-21x3

Is 0.06 bigger than 0.054

Answers

To compare decimals, start by looking at the whole numbers (the number to the left of the decimal).  Since the number for both is zero, next move to the other side of the decimal, the tenths place.  Both numbers are still zero, so now move to the next place over, the hundredths place.  We have a 6 in the hundredths place for one of the numbers and a five in the hundredths place for the other one...  We can stop right there... 6 is greater than 5 so the number with the 6 in the hundredths place is the larger number.

0.06 > 0.054
Tes because the 6 in the hundreths plsce is greater than the 5 in the hundreths plsce

Your dog is 16 years old in dog years. Your cat is 28 years old in cat years. For every human year, your dog ages by 7 dog years and your cat ages by 4 cat years. In how many human years will both pets be the same age in their respective types of years?

Answers

This question is based on the concept of graphical method. Therefore, In 4 years,  human years will both pets be the same age in their respective types of years.

Given:

Your dog is 16 years old in dog years.

Your cat is 28 years old in cat years.

For every human year, your dog ages by 7 dog years and your cat ages by 4 cat years.

Let x be the no. of human yrs.

We have to find x such that age is same for dog and cat in their respective year i.e.

16 + 7x = 28 + 4x

Write above equation as follows and solve it graphically,

y = 16 + 7x

y = 28 + 4x

From the graph, it is observe that. Attachment is below.

Point of intersection is (4, 44). Thus, solution of equation is x =4.

Now put the value x = 4 in  equation 16 + 7x = 28 + 4x.

We get,

16 + 7(4) = 28 + 4(4)

44 = 44

Therefore, In 4 years,  human years will both pets be the same age in their respective types of years.
