<span>3/4(4c+16)=2c+9
We simplify the equation to the form, which is simple to understand
<span>3/4(4c+16)=2c+9
Reorder the terms in parentheses
<span>+(+3c+12)=2c+9
Remove unnecessary parentheses
<span>+3c+12=+2c+9
We move all terms containing c to the left and all other terms to the right.
<span>+3c-2c=+9-12
We simplify left and right side of the equation.
<span>+1c=-3
We divide both sides of the equation by 1 to get c.
<span>c=-3
Hope this helped! :)

Answer:
y = x^2 +6x +8
Step-by-step explanation:
The vertex is located at (-3, -1) and the graph rises 1 unit vertically for 1 unit away from the vertex. This means the scale factor is 1 and the vertex form equation can be written as ...
y = a(x -h)^2 +k . . . . . vertex form with scale factor a, vertex (h, k)
__
y = (x -(-3))^3 +(-1) . . . fill in the values we know
y = (x +3)^2 -1 . . . . . simplify signs
y = x^2 +6x +9 -1 . . . eliminate parentheses
y = x^2 +6x +8 . . . . . your equation in standard form
B = 18 because 18-5 is equal to 3 and 3x3 is equal to 9.
Answer:
x=70
Step-by-step explanation:
x/10=7
First you need to get the x by itself, so you should do the opposite of what is happening to the x.
In this case the x is being divided so you would need to multiply.
So multiply the x by 10 and this gets it by itself.
But you have to do to one side what you do to the other.
So multiply the other side by 10 as well!
This equals x=70
To show work on both sides, show the multiplication of both sides by 10
First you must find a common denominator. In this case 10 will work. You then multiply the top number by whatever you multiplied the bottom number by. This is shown below:
4/5- 3/10 = 8/10- 3/10
You can now solve this to get 5/10. This answer can then be reduced to 1/2.
