What is the sum of two numbers is 40 and their difference is 10
Butoxors [25]

Answer:

<u>The two numbers are 25 and 15.</u>

Step-by-step explanation:

Let's find out the two numbers, this way:

x = first number

y = second number

This is the equations system:

x + y = 40

x - y = 10

Solving for x in the first equation:

x + y = 40

x = 40 - y

Solving for y in the second equation:

40 - y - y = 10

40 - 2y = 10

-2y = 10 - 40

-2y = - 30

<u>y = -30/-2 = 15</u>

Solving for x:

x + y = 40

x + 15 = 40

x = 40 - 15

<u>x = 25</u>

<u>The two numbers are 25 and 15.</u>

A survey of 2,000 doctors showed that an average of 3 out of 5 doctors use brand X aspirin. How many doctors use brand X aspirin
Arlecino [84]
\bf \cfrac{\textit{use X aspirin}}{\textit{don't use X aspirin}}\quad 3:5\qquad \cfrac{3}{5}\qquad \cfrac{3\cdot \frac{2000}{3+5}}{5\cdot \frac{2000}{3+5}}\implies \cfrac{3\cdot 250}{5\cdot 250}\implies \cfrac{750}{1250}
