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

Hello!
3 + 2 = 5
125 divided by 5 = 25
25 x 3:2 = 2
25 x 2 = 50
A)
Because the sum of angles in a triangle must equal 180° we can say:
62+α+90=180
α+152=180
α=28°
b)
Since all sides have equal length, all angles must have equal measure. (This is an equilateral triangle). And again, because the sum of the angle must be 180° we can say:
b+b+b=180
3b=180
b=60°
4 = 2 * 2
Multiplying by 2 is the same a doubling.
Since 4 is 2 * 2, to multiply a number by 4, double the number twice.
Example:
What is 4 * 100?
Double 100 to get 200.
Double 200 to get 400.
Therefore, 4 * 100 = 400.
By doubling twice, we do the same as multiplying by 4.
