Which equation is the result of adding these two equations -2x+4y=17

Katyanochek1 [597]

The right answer is Option C.

Step-by-step explanation:

Given equations are;

-2x+4y=17 Eqn 1

3x-10y= -3 Eqn 2

Adding Eqn 1 and Eqn 2;

$(-2x+4y)+(3x-10y)=17+(-3)\\-2x+4y+3x-10y=17-3\\3x-2x-10y+4y=14\\x-6y=14$

The right answer is Option C.

The sum of three consecutive numbers is 72 what are the smallest of these numbers

Airida [17]

A + b + c = 72

a = b - 1

c = b + 1

(b - 1) + b + (b + 1) = 72

Simplify

3b = 72

b = 24

a = 24 - 1

a = 23

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.
