A television weighs 50 pounds and a microwave

Ilia_Sergeevich [38]

Answer:

Step-50*t + 30*m = 1500, (1) (pounds)

4*t + 3*m = 138. (2) (cubic feet)

From (2), express 3m = 138 - 4t, and substitute it into (1). You will get

50t + 10*(138-4t) = 1500, or

10t = 1500 - 1380 ---> 10t = 1120 ---> t = 112 TVs.

From this point, find the number of microwaves on your own.

Paladinen [302]

Answer:

The number of doctors recommended flash toothpaste 800.

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:

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

By cross multiplying we get:

$5600=7x$

Dividing both sides by 7 we get:

$800=x$

$x=800.$

Therefore, the number of doctors recommended flash toothpaste 800.
