Solve: 4x + 6 = 8x - 18
sladkih [1.3K]

Answer:

x=-3

Step-by-step explanation:

4x+6=8x+18

We simplify the equation to the form, which is simple to understand  

4x+6=8x+18

We move all terms containing x to the left and all other terms to the right.  

+4x-8x=+18-6

We simplify left and right side of the equation.  

-4x=+12

We divide both sides of the equation by -4 to get x.  

x=-3

2 plez!!!?!?!?!?!?!?!?!??!!??!?!?!!??!?!?! I can’t figure it out I’ve tried everything it’s due tomorrow AHAHAHAH
harkovskaia [24]
So to do this one, you have to do the problem backwards!

The equation looks like this with everything plugged in:

272.2 = 2(3.14)r

You are looking for r, so start dividing

272.2 = 2(3.14)r
136.1 = (3.14)r
43.3 = r

Therefore the radius is about 43.3 in.

I hope I helped!

Identify the graph of the equation. What is the angle of rotation for the equation?<br><br>xy=-2.5
Maurinko [17]

Answer:

It is B. hyperbola, 45 degrees.

SteIt is p-by-step explanation:

If we rotate the standard form  x^2 - y^2 = 1 through 45 degrees we get xy = 1/2.

xy = -2.5 comes from x^2 - y^2 = -5  being rotated 45 degrees.

Helen spent $145 for shoes. This was $55 more than twice what she spent for a bag. How much was the bag?
marin [14]

Answer:

45 DOLLARS

Step-by-step explanation:

For these kind of problems, write an equation to figure out the answer.

55 + 2x = 145

x represents the bag cost

145 is the shoe cost

Take out the constant, which is 55, from both sides. A constant is a useful term you should learn.

The result is: 2x = 90

Divide 2x by 2, to get x, which is the bag cost, by itself.

Result: x= 45

Since x is the bag cost, the bag costs 45 dollars
