The sum of two numbers is 44. One number is 2 more than twice the other. Write a system of equations that defines this situation

hram777 [196]

System: x + y = 44; x = 2y + 2

Solve with substitution: x = 30; y = 14

x + y = 44
x = 2y + 2

Substitute 2y + 2 for x

2y + 2 + y = 44

3y + 2 = 44

Subtract 2 on both sides.

3y = 42

y = 14

Now substitute back in.

x + 14 = 44

Subtract 14 on both sides.

x = 30

Answer: 0.01429

Step-by-step explanation:

1.429 x $10^{-2}$

Now $10^{-2}$ is just 1/100 or 0.01, because 10^2 is 100

Now we can multiply 1.429 by 0.01 which is 1.429 x 0.01

Or the easy way, we can just place the decimal two places to the left because the power is -2, so 2 places to the left. Moving the decimal to the left makes the number smaller.

So, take 1.492 and move its decimal 2 places to the left

We get 0.01429
