The answer is C) x = 5

Here are the steps I did.

1. Expand ( 2x + 8 = x + 13)

2. Subtract 8 from both sides ( 2x = x + 13 - 8)

3. Simplify x + 13 - 8 to x + 5 ( 2x = x + 5)

4. Subtract x from both sides ( 2x - x = 5)

5. Simplify 2x - x to x ( x = 5)

A frog weighs 3/5 lb. What is the mass of the frog in kilograms 1 ib equals 0.45 kg?

sergejj [24]

The mass of the frog will be 0.27 kilograms.

Explanation

The weight of the frog is $\frac{3}{5}$ pound.

As 1 pound = 0.45 kilograms,

So for finding the mass of the frog in kilograms, we need to multiply $\frac{3}{5}$ by 0.45

Thus, $\frac{3}{5}*0.45= \frac{1.35}{5}=0.27$

So, the mass of the frog will be 0.27 kilograms.

What is the slope of the line that passes through the points (4, 9) and (1, 6)?

Aleksandr [31]

a = ( 1 , 6 )

b = ( 4 , 9 )

$slope = \frac{y(b) - y(a)}{x(b) - x(a)} \\$

Now just need to put the coordinates in the above equation :

$slope = \frac{9 - 6}{4 - 1} \\$

$slope = \frac{3}{3} \\$

$slope = 1$

And we're done...♥️♥️♥️♥️♥️

What is the probability that the sun will rise tommorow?

zvonat [6]

Answer:

100 percent the sun will rise tomorrow but who is to say you will get to see the sun tomorrow? who is to say you won't have a heart attack and die on this material planet tomorrow and won't get to see the sun rise. or what if the sun sends out a solar flare and burns everyone to a crisp and completely demolishes our ozone layer allowing oxygen to excrete from the planet and cooking everyone with solar radiation all at the same time catastrophic winds and earthquakes demolish the planet because of loss of pressure from the gravity field held in check by the oxygen that has left the planet from a destroyed ozone layer leaving everyone to suffocate and die and excruciating death therefore yes the sun will rise tomorrow but certain events are to unfold we could never prognosticate
