The value of y varies directly with x. If x =3, then y=21. What is the value of x when y=105?

Goshia [24]

Answer:

x = 15

Step-by-step explanation:

given that y varies directly with x

mathematically we can express this as

y = k x , where k is a constant

step 1: find k

given x = 3 and y = 21

y = k x

21 = k (3)

k = 7

hence the equation becomes

y = 7 x

when y = 105,

105 = 7x

x = 105 / 7 = 15

John walks 3 miles in 5 hours for his exercise routine. Find the Unit rate

Brilliant_brown [7]

John walks 0.6 miles in 1 hour.

Step-by-step explanation:

Distance walked by John = 3 miles

Time period = 5 hours

5 hours = 3 miles

Unit rate is the ratio of two measurements, in which one measurement is one, therefore,

1 hour = $\frac{3}{5}\ miles$

$1\ hour=0.6\ miles$

John walks 0.6 miles in 1 hour.
