Answer:

4x+20=

6x-10

Step-by-step explanation:

Simplifying: 4x + 20 = 6x + -10

Reorder the terms: 20 + 4x = 6x + -10

Reorder the terms: 20 + 4x = -10 + 6x

Solving: 20 + 4x = -10 + 6x

Solving for variable 'x'.

Move all terms containing x to the left, all other terms to the right.

Add '-6x' to each side of the equation: 20 + 4x + -6x = -10 + 6x + -6x

Combine like terms: 4x + -6x = -2x: 20 + -2x = -10 + 6x + -6x

Combine like terms: 6x + -6x = 0: 20 + -2x = -10 + 0: 20 + -2x = -10

Add '-20' to each side of the equation: 20 + -20 + -2x = -10 + -20

Combine like terms: 20 + -20 = 0: 0 + -2x = -10 + -20: -2x = -10 + -20

Combine like terms: -10 + -20 = -30: -2x = -30

Divide each side by '-2': x = 15

Simplifying: x = 15

Two numbers have difference of 0.7 and a sum of 1. What are the numbers?

algol [13]

We can solve this by setting up 2 equations. We can use any letters like. For now, I'll use x and y.
So now we know that    x - y = 0.7   and    x + y = 1.
Now we can eliminate one of the letters by adding or subtracting one equation from the other. I am going to eliminate y by adding the two together (the y and the -y cancel).
This gives us   2x = 1.7,    and so x = 1.7 ÷ 2 = 0.85
Finally, we can substitute x for 0.85 back into one of the original equations to figure out what y equals. I'm going to use   x + y = 1.
So now we have   0.85 + y = 1,    so y = 1 - 0.85 = 0.15

The numbers, therefore, are 0.85 and 0.15 (you can check by using the other equation).

Hope this helps!

Find the slope of the line through each pair of points (-12,0) (20,0)

AlexFokin [52]

$\frac{y2}{x2} - \frac{y1}{x1}$
That is the formula to find the slope. Hope it will help you.

Calculate the distance between the two given point T(6,-2),U(-2,-12)

slava [35]

Use the distance formula: $\sqrt{(x2 - x1)^2 + (y2 - y1)^2}$

(6, -2), (-2, -12)
$\sqrt{(-2 - 6)^2 + (-12 - -2)^2}$ ⇒ $\sqrt{(-8)^2 + (-10)^2}$
$\sqrt{64 + 100}$ ⇒ $\sqrt{164}$
$\sqrt{164}$ = 12.8

The distance between points T and U is 12.8 units.

A conjecture and the paragraph proof used to prove the conjecture are shown.

quester [9]

First box is EF.

Second box is segment congruence postulate.

Third box is segment additon postulate.

Fourth box is DF. For this one the last sentence basically gives you the answer.

Just so you know for the fourth I guessed on if it's DF lined or DF unlined. I made my educated guess on the fact that the last line doesn't have a line. I hope this helps, and please tell me if I got something wrong, or my explanation wasn't sufficent enough for you.
