1)
g+4-3g=1+g
subtracting g from both sides
4-3g=1
subtracting 4 from both sides
-3g=-3
g=1
2)
-6a+3=-3(2a-1)
extending the right side
-6a+3=-6a+3
adding 6a to both sides
3=3
which is an identity
3)
0.5b+4=2(b+2)
extending the right side
0.5b+4=2b+4
subtracting 0.5 b from both sides
4=1.5b+4
subtracting 4 from both sides
0=1.5b
b=0
4)
8-(3+b)=b-9
subtracting 8 from both sides
-(3+b)=b-17
extending the left side
-3-b=b-17
adding b to both sides
-3=2b-17
adding 17 to both sides
14=2b
b=7
Answer:
z = - 1
Step-by-step explanation:
z + (z - 6) - 2 = - 10 ← remove the parenthesis on left side
z + z - 6 - 2 = - 10 , that is
2z - 8 = - 10 ( add 8 to both sides )
2z = - 2 ( divide both sides by 2 )
z = - 1
Answer:
9 3/8
Step-by-step explanation:
or 75/8
Answer:
A) y = 5
Step-by-step explanation:
Points: (1, 5) and (3, 5)
Slope:
m=(y2-y1)/(x2-x1)
m=(5-5)/(3-1)
m=0/2
m = 0
Since 0 is the slope, that means there's no slope.
y - y1 = m(x - x1)
y - 5 = 0(x - 1)
y - 5 = 0
y = 5
