Answer:
What kind of problem? Multiplication? Division? What?
Step-by-step explanation:
Answer is a = -4
3a + 4 = 2a
Subtract 2a from each side
a + 4 = 0
Subtract 4 from each side
a = -4
Answer:
90
Step-by-step explanation:
The angle formed outside = 1/2(difference of intercepted arcs)
The large arc is 360-x and the inner arc is x
x = 1/2 (360 -x - x)
x = 1/2 (360 -2x)
Multiply each side by 2
2x = 360 -2x
Add 2x to each side
2x+2x = 360
4x= 360
Divide by 4
4x/4 = 360/4
x = 90
1. Simplify both sides
−6n=−5−5n
−6n=−5+−5n
−6n=−5n−5
2. Add 5n to both sides
−6n+5n=−5n−5+5n
−n=−5
3. Divide both sides by -1.
−n
/−1
=
−5
/−1
n=5
So the variable n, is equal to 5
