Solve 9(8 - x) = 3x.

Mathematics

bulgar [2K]3 years ago

Hello - let's do this step by step. Show your work.

You're asking: 9(8−x)=3x.

Now, simplify both sides of the equation.

9(8−x)=3x

(9)(8)+(9)(−x)=3x (To do that, distribute)

72+−9x=3x

−9x+72=3x

Now,  subtract 3x from both sides.

−9x+72−3x=3x−3x

Simplify,

−12x+72=0

After, subtract 72 from both sides.

−12x+72−72=0−72

−12x=−72

Last thing, divide both sides by -12.

-12x/12 = -72/-12

Divide.

Therefore, you have <u>x = 6</u> as your final answer.

Step-by-step explanation:

Step 1:

y = mx + b     Slope Intercept Form

Step 2:

y = -x + b     Input Slope

Step 3:

7 = - 1 ( 1 ) + b    Input x and y

Step 4:

7 = - 1 + b      Multiply

Step 5:

b = 8     Add 1 on both sides

Answer:

y = - x + 8

If 4 is the constant of proportionality is this equation correct? y = 4x + 2​
max2010maxim [7]

Answer:

4 is not the constant. 2 is.

Step-by-step explanation:

In the following equation: y = 4x + 2

x and y are variables. x can be any given number, and y would be the resulting answer.

4 is not the constant, because the product it will produce varies on what x will be.

2 is a constant, because it will not change regardless what is put into x. It will continue to stay as 2.

Step-by-step explanation:

360° around a point

65° x 2 = 130

360 - 130 = 230

230/2 = 115

115 ° are corresponding angles

where would an imaginary line need to be drawn to reflect across an axis of symmetry so that a regular pentagon can carry onto i
irina [24]

Answer:

An imaginary line would need to be drawn at any angle to the center of the side opposite the angle to  reflect across an axis of symmetry so that a regular pentagon can carry onto itself. Hope this answer helps.

These are the first sentences in the short story, "The Gift of the Magi," by O. Henry:
Aleonysh [2.5K]

I think the answer to this is: 25q + 10d + 5n + 60 = 87

The story says that you have 1 dollar and 87 cents; 60 cents of which is pennies. So, if you’re using an equation involving quarters, dimes and nickels, the total equation should equal to 87 cents (since that dollar bill could not be broken down to cents).
