Angles 1 and 8 are created by line t intersecting with line m.


Line t is called a transversal line, because it intersects 2 parallel lines.

t divides the straight angle formed by m alone, forming the linear pair of angles (1) and (8), whose sum is 180 °, that is they are supplementary.


Answer: (1) and (8) are linear pairs

Because 1 and 8 are on a line and are a linear pair, that makes them supplementary. Linear pair definition is the reason.

8x + 2 – 6 = 4x +8 +3x
Viefleur [7K]
The first step is to combine like terms. So u would do 2-6. You then get -4 then u just bring everything else down. So now u should have this :

8x -4 = 4x + 8 + 3x

Now you do the same thing to the other side. U combine like terms which in this case are 4x and 3x. So u just do 4+3 which is 7 so now u have 7x. So now ur equation would be:

8x -4 = 7x +8

Now u do the inverse of 7 which would be -7 and u do that on both sides. So it would look like this :

8x -4 = 7x + 8
-7x. -7x

So now 7 and -7 cancel each other other and 8 -7 is 1 so now u have one x. So ur equation would now look like this:

1x -4 = 8

Now u do the inverse of negative 4 which is +4. So you would add 4 on both sides on both sides. Like shown:

1x -4 = 8
+4 +4

So u just add 8 + 4 which is 12. Now since anything times 1 is itself ur answer will be X=12


Hope this helped

Slove for X= what would this be for Mai poured 2.6 liters of water into a partially filled pitcher. The pitcher then contained 1
alexandr1967 [171]

Answer:

  x + 2.6 = 10.4

  x = 7.8

Step-by-step explanation:

If 2.6 liters are added to x liters with the result that 10.4 liters then exist, the model is ...

  2.6 +x = 10.4 . . . . . . . 2.6 added to x gives 10.4

The commutative property of addition lets you rewrite this to ...

  x +2.6 = 10.4

__

Subtracting 2.6 from both sides of the equation gives its solution:

  x +2.6 -2.6 = 10.4 -2.6

  x = 7.8

What is 267.4 divided by 1/10 ?
kotegsom [21]
I’m personally not to good at adding fractions so I turned 1/10 into 0.1

Then I divided 268.4 by .1 and got 2,674.

Trey deposited 20% of his paycheck in the bank. if he deposited $30 how much was his paycheck
Komok [63]

Answer: 150

Step-by-step explanation: so when you want a whole amount of something you want to the 100% of it because 100% is the whole thing right? Well right now you only have 20% so how much do you need to multiply that by to get 100%?? Well that answer is 5. Okay so now since $30 is 20% but we wanna get it to 100% multiply it by 5 so 30x5 which is 150
