Paladinen [302]

Answer:

The number of doctors recommended flash toothpaste <u>800</u>.

Step-by-step explanation:

Given:

A magazine ad states that 4 out of 7 doctors recommend Flash toothpaste.

Now, to find the numbers of doctors recommended flash toothpaste if 1400 doctors were surveyed.

Let the number of doctors recommended be $x$ .

And the total number of doctors surveyed were 1400.

So, as given 4 out of 7 doctors recommend flash toothpaste.

So, 4 equivalent to 7 = $\frac{4}{7}$ .

And, $x$ equivalent to 1400 = $\frac{x}{1400}$ .

Thus, we set the proportion and solve by cross multiplication method:

$\frac{4}{7} =\frac{x}{1400}$

<em>By cross multiplying we get:</em>

$5600=7x$

<em>Dividing both sides by 7 we get:</em>

$800=x$

$x=800.$

Therefore, the number of doctors recommended flash toothpaste 800.

STALIN [3.7K]

Answer: The value of x and y are 2 and 15 respectively.

Step-by-step explanation:

Since we have given that

Number of hours available in graphics = 21 hours

Number of hours in printing = 19 hours

Number of hours required by x in graphics = 3

Number of hours required by x in printing = 2

Number of hours required by y in graphics = 1

Number of hours required by y in printing = 1

According to question, we get that

$3x+y=21\\\\2x+y=19$

Using the graphing method, we get that

x = 2 and y = 15

Hence, the value of x and y are 2 and 15 respectively.

Anyone know this answer?

Tasya [4]

Answer:

16

Step-by-step explanation:

Remember to use pemdas:

8÷2(2+2)

First we do whats in parentheses.

= 8÷2(4)

Then we do multiplication and division from left to right

= 4(4)

= 16

So the answer is 16. Remember that multiplication and division have the same priority in pemdas, and you should always do them left to right, because order does matter.
