Answer:
53
Step-by-step explanation:
so first sutract the large angle from 360:
360 - 213 = 147
then subtract the other large known angle:
147 - 107 = 40
now we know the x - 13 = 40 so to find x we just have to add 13:
40 + 13 = 53
It is 1,000 times the 4 in the tens place if that is what they are asking.
Hope this helps!
Answer:
5x-3=3x+5
5x-3x=5+3
2x=8
x=8/2
x=4
Therefore,
Value of 2x-8
Substitute the value of x
2(4)-8
8-8=0

THANK you.....
Answer:
(2,-10)
x=2
y= -10
Step-by-step explanation:
To solve by combining the equations we first need to get everything in linear form.
For both equations we can simply just add y to both sides and then subtract the other number on the right side. Doing this gets us
-2x-6=y
-7x+4=y
We then set the two equations equal to each other and solve for y
-2x-6= -7x+4
add 7x and 6 to both sides and get
5x=10
x=2
Use this x value and plug it into any equation
let's do it on the first
-2(2)-y=6
Solve for y and get
-y=10
which means that
y= -10
