Answer: 7 years old
Explanation: so first we know he has to be at least 1 year old. we can think of the multiples of 9 that are greater than 56 because he will be 9 times as old. so 63 is a multiple of 9. 63-56=7. kevin is 7 right now, and in 56 years, he’ll be 63, which is 9 times as old as he is now.
hope this helped!
X = 1, 2, 5, 10
y = 40,20, 8, 4
a) y = 40x
y = 40(1) = 40 ; y = 40(2) = 80 ;
y = 40(5) = 200 ; y = 40(10) = 400
b) y = (1/40)x ;
y = (1/40)1 = 1/40 ; y = (1/40)2 = 1/20 ;
y = (1/40)5 = 1/8 ; y =(1/40)10 = 1/4
c) xy = 40 ⇒ y = 40/x
y = 40/1 = 40 ; y = 40/2 = 20
y = 40/5 = 8 ; y = 40/10 = 4
Inverse variation. Choice C. xy = 40 is the correct answer.
Lyn's speed is 3 miles per hour.
That is distance travelled in 60 minutes
= 3 miles
So, distance travelled in 25 minutes
= 3 * 25 / 60 miles
= 25/ 20 miles
= 1.25 miles
New speed of Lyn is 5 miles per hour
That is, for travelling 5 miles, time required = 60 minutes
So, for travelling 1.25 miles, time required = 60 * 1.25 / 5 minutes
= 60/ 4 minutes
= 15 minutes.
It will take her 15 minutes, if she runs at a speed of 5 mph.
