Answer:

x = \frac{1}{2}

Step-by-step explanation:

First we have to distinguish the whole numbers from the numbers with variables.

2x and 5x are numbers with variables, 6 and 0 are whole numbers.

Then we can seperate them on different sides of the equal sign.

To do this, we have to subtract 6 on the left side and add it to the right side.

Now our equation will be 2x - 5x = -6.

Now we can simplify this.

Starting on the left side, 2x - 5x equals to -3x.

The right side can not be simplified.

So, our equation will now be -3x = -6.

Now we can divide both sides together.

The easiest way to do this is by turning the equation into a fraction.

So it will be \frac{-3}{-6}.

Both equal signs cancel out, so the answer will be \frac{1}{2}.

Hope this helped :)

One number is eight less than a second number. Twice the first is 12 more than 4 times the second. Find the numbers.
tia_tia [17]

Answer:

Step-by-step explanation:

"One number is eight less than a second number."

x = y-8

"Twice the first is 12 more than 4 times the second."

2x = 4y+12

substitution

2(y-8) = 4y + 12

2y - 16 = 4y + 12

2y = -28

y = -14

x = y-8 = -22

I need help with this problem
Anarel [89]

The midpoint lines are half the opposite side length.

Line DE is given as 7 , So Line F = 7 x 2 = 14

Line EF is given as 12, so Line D = 12 x 2 = 24

Line DF is given as 16, so line E = 16 x 2 = 32


The perimeter is the sum of the 3 sides:

Perimeter = 14 + 24 + 32 = 70

Point L is on line segment KM. Given LM=11 and KL=4, determine the length KM.
Scorpion4ik [409]

Hey there! I'm happy to help.

Let's think of the line segment KM as a road. It starts at point K and ends at M. You start driving from point K and after 4 miles, you have reached point L. The segment KL is equal to 4 because the distance between K and L is 4.

From point L to point M, you drive 11 miles. You are now at the end of the road. We want to find out how long the road is.

From point K to point L, you drove for 4 miles.

Then, from L to M, you drove 11.

We combine these...

11+4=15

The length of KM is 15.

Have a wonderful day! :D
