When dividing fractions, we follow a rule called "Keep, change, flip"
Basically, you keep the first fraction the same, change the sign to a multiplication sign, and flip the second fraction.
2 = 2/1
7 * 1 + 6 = 13
2/1 * 7/13 = 14/13 = 1 1/13
2 divided by 1 6/7 = 1 1/13
3 3/5 = 18/5
2 1/4 = 9/4
18/5 * 4/9 = 72/45 = 8/5 = 1 3/5
3 3/5 divided by 2 1/4 = 1 3/5
4 1/2 = 9/2
2 3/8 = 19/8
9/2 * 8/19 = 72/38 = 36/19 = 1 17/19
4 1/2 divided by 2 3/8 = 1 17/19
67.5 degrees //////////////
The 2 interior angles add to the exterior angle
26+13=x
39=x
x=39°
because
remember, all angles add to 180
26+13+BCA=180
39+BCA=180
minus 39 both sides
BCA=141
look, we want x
BC is a striaign line which is 180
BCA+x=180
141+x=180
minus 141 from both sides
x=39°
<span>If f(x)= 2x^2 -4x and g(x) = 5 – 2x, evaluate f(x) – g(x) for x = 5
you first plug in 5 for x in both equations...
(2(5)^2-4(5))=f(x)
5-2(5)=g(x)
now you evaluate...
(2(25)-20)-5-10
50-30-15
20-15=5
Answer:
5
