\huge\boxed{c=3.5a}

First, we need to find how much a single pound of apples costs.

Do this by dividing.

\frac{\$7}{2\ \text{lbs.}}\div\frac{2}{2}=\frac{\$(7\div 2)}{(2\div 2)\ \text{lbs.}} = \frac{\boxed{\$3.50}}{1\ \text{lb.}}

Now, write an equation.

\large\boxed{c=3.5a}

This represents that the cost equals 3.5 times the number of apples.

Answer:

3.5a=c

Step-by-step explanation:

You can do this in two ways:

Way ONE:

In this scenario:

a=2

c=7

If you plug those numbers into the equation, you get:

3.5*2=7

This statement is correct.

Way TWO:

$7/2=3.50. This is the cost PER POUND OF APPLE.

That means:

<u>Every pound of apple, a, times 3.50, will give you your cost.</u> This is basically just reversing 7/2=3.50, our first statement.

In equation form, the underlined statement would look like this:

a*3.5=7, or our answer:

3.5a=7

Answer:

A=35, B=55, and C=25

Step-by-step explanation:

Angle A and the angle next to it are linear pairs, so you can subtract 145 from 180.

if you already know Angle A, and that the other angle is 90 degress, you can add 90+35 and subtract it from 180 to get Angle B

Angle C is paired with the angle across from it (I forgot what the term is called) so it is 25 degrees.

In a recent year, 27.9% of all registered doctors were female. If there were 53,700 female registered doctors that year, what wa
Elis [28]

Answer:

The total number of registered doctors was 192,473.

Step-by-step explanation:

This question can be solved using a rule of three.

53700 is 27.9% = 0.279. The total number of registered doctors is x, which is 100% = 1. So

53700 doctors - 0.279

x doctors - 1

0.279x = 53700

x = \frac{53700}{0.279}

x = 192473.11

Rounding to the nearest whole number.

The total number of registered doctors was 192,473.
