Answer:
a = 30°
Step-by-step explanation:
We need to find the value of a.
We know that, a straight line makes an angle of 180°.
In this case,
a+3a+2a = 180
6a = 180
a = 30°
So, the value of a is equal to 30°.
First, find the LCD of the two fractions.
Multiples of 12: 12, 24, 36, 48, 60.
Multiples of 20: 20, 40, 60
The LCD is 60.
Second, change the denominators to be the same as the LCD.
Third, 5 × 5 = 25 / 12 × 5 = 60 / 3 × 3 = 9 / 20 × 3 = 60
Fourth, combine the denominators.
Fifth, subtract 25 - 9 to get 16.
Sixth, find the GCF of 16 and 60.
The GCF is 4.
Seventh, divide the numerator by the GCF.
÷
Eighth, divide the denominator by the GCF.
÷
Ninth, rewrite the fraction in simplest form.

Answer as decimal: 0.2667
Answer:
y = 2x - 13
Step-by-step explanation:
Slope intercept equation of a line
y = mx + b
m is the slope = 2
y = 2x + b
To find "b" plug in the given point (4, -5)
-5 = 2(4) + b
-5 = 8 + b
Subtract 8 from both sides
-13 = b
Using m = 2 and b = -13 the equation becomes
y = 2x - 13
Sheeeeeeeeeeesh I feel bad for you
