Slope intercept is y=Mx+b where m is always the slope and b is always your y intercept. The point slope fo is y-y^1=m(x-x^1) where x1 and y1 are a known point and m is the still the slope. X and y is another point on the linear equation
The sequence:
a 1 = 30, a 2 = 70, a 3 = 110, a 4 = 150, a 5 = 190,...
a 2 = a 1 + d
70 = 30 + d
d = 70 - 30 = 40
a n = a 1 + ( n - 1 ) * d
For the 25th month:
a 25 = 30 + 24 * 40 = 30 + 960 = 990
Answer: B ) 990.
Ok so
1/4 of total eaten
3/4 left
3/5 of 3/4 eaten
9/20 left
18=9/20 of whole
multiply both sides by 20
360=9 of whole
divide both sides by 9
40=whole
40 total originlly
Answer:
50 minutes
Step-by-step explanation:
x=9
(5x9+5)+9+13=72
50+9+13=72
59+13=72
5x9=45
45+5=50
