Common difference (d) = - 14-(-17)
d = -14+17
d = 3...
Tn = -17+(n-1)3
Tn = - 17+3(n-1)
Option a is correct.....
The answer is in the picture
Answer:
the ratio of Jan's average walking rate to Bev's average walking rate is 3/4 or 3 : 4
Step-by-step explanation:
Let x and y represent jan and Bev's average walk rate.
Also t represent the time taken for Bev to walk 4 miles, so it will take jan 2t time to walk 6 miles
Given that;
It takes Jan twice as many hours to walk 6 miles as it takes Bev to walk 4 miles
For Bev;
y = 4/t
For Jan;
x = 6/(2t) = 3/t
the ratio of Jan's average walking rate to Bev's average walking rate is;
x/y = (3/t)/(4/t) = 3/4
the ratio of Jan's average walking rate to Bev's average walking rate is 3/4 or 3 : 4
Answer:
The elephant could eat 250,000 pounds of food in 1000 days
Step-by-step explanation:
Factor out the gcf first.
3(4y^2-9)
The binomial inside is a perfect square so keep factoring.
3(2y+3)(2y-3)
The pair of binomials cannot be further factored so stop there.
