5+3r=5r-19(if there is no solution,type in ''no solution'')r= Answer

TEA [102]

Answer: 12 = r

Step-by-step explanation: When we have this kind of a setup, we want to put our variables together on one side of the equation and our numbers together on the other side of the equation.

First, let's put our variables on the right side by subtracting 3r from both sides of the equation. That gives us 5 = 2r - 19.

Now we can move our numbers to the left by adding 19 to both sides of the equation and we get 24 = 2r.

Divide both sides by 2 and 12 = r

Note:

Don't just do this problem in your head. It's extremely important to develop the habit of putting all your steps down on paper or digitally. It will really pay off for you down the line.

Expansion of a^4+b^4

amid [387]

Answer:(a+b)^4

Step-by-step explanation:

You first see what they both have in common. In this case it is the the 4 squared. You then take that out and you see what is left. The thing that is left is a+b.

So you put the a+b inside the parentheses and the 4 squared outside.

so your answer will be (a+b)^4.

Hope this helped.

Plz answer this im going to fail the semester :(

Answer and Explanation

__________________________________________________________

<h2>The solution of the equation is 20. </h2><h3>( The value of x. )</h3>

__________________________________________________________

The value of x is 20.

We can figure this out by...

__________________________________________________________

$\frac{3x}{5}-x=\frac{x}{15}-\frac{28}{3}$ but what does x equal?

$\frac{3\cdot20}{5}-20$ = $-8$

$\frac{20}{15}-\frac{28}{3}$ = $-8$

Since both are equal to -8, that means $\frac{3\cdot20}{5}-20$ = $\frac{20}{15}-\frac{28}{3}$ .

Which means that...

x = 20

the space station has an average orbit of 250 miles above the earth. how many pennies would it take to make a stack that high? p

hram777 [196]

Answer:

264694796.312

Step-by-step explanation:

A penny is 0.0598 inches (1.52 mm) in thickness. (0.75 is the diamiter).

Hear me out. Now we gotta convert it to miles to divide 250 by the number (there's 6.21371e-7 miles in one mm). first convert the mm to inches (by dividing the length value by 63360). We get 9.444842171717e-7 or 9.44484e-7 for a shorter form. Last step 250/9.444842171717e = 264694796.312.

Oh btw I'm not very sure on this answer correct me please if I'm wrong.
