an art gallery has 18 paintings and 4 photographs displayed in equal rows on a wall with the same number of each type of art in each row which of the following could be the number of rows

Answers

Answer 1

Answer: So if there are 18 paintings and 4 photographs, then they need to be divided evenly into equal groups/rows.
18÷2=9
4÷2=2

A. 2 rows can be possible with 9 paintings and 2 photographs in each row.
B. 3 rows are not possible because none of the numbers can be divided by three.
C. 4 rows cannot be possible. While 4 can be divided by 4, 18 cannot.
D. 6 rows cannot be possible because the only number that can be divided by 6 is 18, which would be three. 4 is not divisible by 6.

You were right, the answer is A. with each row containing 9 paintings and 2 photographs!

Solve using substitution technique; -3x+y=2, 12x-4y=-8

Answers

The first equation is easier to solve for y than is the 2nd: y = 3x+2. Subst. 3x+2 for y in the second equation:

12x - 4(3x+2) = -8

Expanding, 12x =12x -8 = -8

This is always true, no matter the value of x. Thus, the solution set is "all real numbers."

If 2b= -3, what is the value of 1 – 4b?

Answers

If we have the expression 2b = -3, then the value of the expression 1 - 4b is 4.

Step 1: Solving for 'b'

We are given the equation 2b = -3. To isolate 'b,' we need to get rid of the coefficient 2 attached to 'b'. To do that, we'll divide both sides of the equation by 2:

2b / 2 = -3 / 2

b = -3/2

Step 2: Substitute 'b' in the expression 1 - 4b

Now that we have the value of 'b' as -3/2, we can substitute it into the expression 1 - 4b:

1 - 4(-3/2)

Step 3: Simplify the expression

To simplify the expression, we'll perform the multiplication first:

1 + 6/2

Next, we add 1 and 6/2:

1 + 3 = 4

A bag of apples weighs 7 7/8 pounds and a full bag costs $10.88. By weight 1/18 of the apples are rotten . What is the cost of the bag if the bad apples are removed?

Answers

Answer: Hello there!

We know that a bag of apples weighs (7 + 7/8) lb and costs $10.88

But 1/18 of the apples are rotten, if we remove the rotten apples, we still have the other 17/18 portion of the bag to pay.

then; if the full bag costs $10.88, how much does it cost a 17/18 of the bag?

this is (17/18)*$10.88 = $10.28

Then if you remove 1/18 of the apples, the bag costs 10.28 dollars.

notice that I did not use the weight of the apples, in a lot of math problems you will have more information than the needed, and you need to know when the information is useful and when it is not.

Try Analysing The Information Like This, Step by Step;

1. We know that a full bag of 7 7/8 pounds and is $10.88.
2. Now we subtract the bad apples 7 7/8-1/18= a (now we have no bad apples).
3. Part 'a' answer will give you a no. in pounds.
4. Part 'b' - we have to find out $10.88/7 7/8 - 1/18 / 2 to give you the answer.

I hope this helps, sorry I couldn't really help you :)
