15^ is equivalent to 0.15, or 15/100. If you divide both numerator (15) and denominator (100) by 5, you get 3/20.
28% corresponds to 0.28. What fraction would that be?

Answer:
See below
Step-by-s.ep explanation:
6. Let the 3 integers be k-2, k and k+2.
So k(k+2)-k(k-2) = 28
k^2 + 2k - k^2 + 2k = 28
4k = 28
k = 7.
So the 3 integers are 5, 7 and 9.
Answer:
F=140°
Step-by-step explanation:
130+120+110=360
720-360=360
40+60+20=120 360+120=480
480÷3=160 x=160
160-20=140
f=140°
Answer:
Step-by-step explanation:
Given that
Slope m=-3
A point (x, y)=(4,-2)
Equation of a line can generally be written as
y=mx+c
Where, m is the slope
And c is the intercept on y-axis
Since we are given m=-3
Then, y=mx+c becomes
y=-3x+c
To get c, let substitute the point given, i.e x=4 and y=-2
y=-3x+c
-2=-3(4)+c
-2=-12+c
-2+12=c
c=-2+12
c=10
y=mx+c, then m=-3 and c=10
Then, the equation the line becomes y = -3x + 10
This is the required line equation
