Let the number be x.
4x - 8 =12
4x =12 +8 ( you bring the eight over to the 12, it becomes positive )
4x = 20
x = 20÷4
x = 5
Answer:
-11
Step-by-step explanation:
The given expression is:
=
=
=
Substituting the value of b=-2 in above expression, we get
=
=
=
Thus, the value of the given expression is -11.
I got 2400 because 120 x 80 = 9600 divided by 4 = 2400 idk i may be wrong

Answer:
x = 15
WX = 34
Step-by-step explanation:
Part 1:
We know that arc AB and AC have to be equal because the lines splitting off from the center point are congruent to eachother.
Lets start by subtracting 106 from 360, which gives us 254. We know that both of our missing arcs have to add up to equal 254 and we also know that they're congruent. This means we can simply divide 254 by 2 to get 127 and set that equal to our 10x - 23.
10x - 23 = 127
Get x by itself
10x = 150
x = 15
Part 2:
Since we're assuming both XY and XW are tangent we're just going to set them equal to eachother.
7x - 29 = 2x + 16
Get your Xs on one side and your constants on the other.
5x = 45
Divide
x = 9
Plug in your x
7(9) - 29
63 - 29
WX = 34
