30-24=6 6/30=0.2
0.2x100=20
20%
3x - 6 = 7x + 18
(Move terms)
3x - 7x = 18 + 6
(Collect the terms)
(Calculate the sum)
-4x = 24
(Divide both sides by -4)
x = -6
A the slope of the line is 1
to calculate the slope m , use the ' gradient formula '
m = ( y₂ - y₁ ) /( x₂ - x₁ )
where (x₁, y₁ ) = 6, 3) and (x₂, y₂ ) = (9, 6)
m =
=
= 1

Answer:
3/8
Step-by-step explanation:
With unlike denominators find the Least Common Denominator (LCD)
LCD = 8
Multiplying numerators and denominators to get the LCD in all fraction denominators
=3/4 times 2/2−3/8
Then rewriting the equation with the equivalent fractions
=6/8−3/8
With like denominators we can operate on just the numerators
=6−3/8
=3/8
