Answer:
x = 14 and 2/3
Step-by-step explanation:
Make an equation where x is the number.
2x - 15 = 7 + 1/2x
Then, solve the equation.
multiply both sides by 2 to get rid of the fraction
4x - 30 = 14 + x
subtract x from both sides
3x - 30 = 14
add 30 to both sides
3x = 44
divide both sides by 3
x = 14 and 2/3
Answer:
Suppose we have a total of 16 drummers.
for the first pattern we have 2 drummers in each row, this means that we have a total of 16/2 = 8 rows.
Now, for the second pattern, we have 4 times as many in each row, so we have 4*2 = 8 drummers in each row, then we have 16/8 = 2 rows.
You can see that in each pattern we have the same number of drummers, but a different number of rows.
Now, we only can do this if the total number of drummers is a multiple of 8 (because in the second part we want 8 drummers in each row, so if we want that the numbers of rows to be a whole number, then we must have that the total number of drummers is a multiple of 8)
Answer:
Step-by-step explanation:
Let the total purchase be given as 'p' dollars.
Given:
Price of a notebook = $5
Price of a pen = $1.50
Number of pens purchased = 'x'
Number of notebooks purchased = 1
So, cost of 'x' pens can be obtained using unitary method and is given as the product of price per pen and number of pens.
So, price of 'x' pens = Price per pen 
Number of pens
Price of 'x' pens = 
Now, total purchase price will be equal to the sum of the price of a notebook and price of 'x' pens.
Therefore, the total purchase price is given as:
Total price = 1 notebook price + 'x' pens price

Answer:
x = Ø
Step-by-step explanation:
7x - 12 - 3x = 2(2x + 5)
4x - 12 = 4x + 10
4x = 4x + 22
0x = 22
x = Ø
