Courtnee runs 5/8 of a mile in 2/4 of an hour. What is Courtnee's rate in
miles
per hour?

Courtnee's rate in  miles  per hour will be = 1.26 miles per hour

Step-by-step explanation:

Courtnee's rate in miles  per hour can be calculated by dividing the number of miles i.e. 0.63 miles by the time taken i.e. 0.5 hours.

Therefore,

Courtnee's rate = 0.63 miles / 0.5 hour

                           = 1.26 miles per hour

Therefore,

Courtnee's rate in  miles  per hour will be = 1.26 miles per hour

let m = monomial

let t = trinomial

so, m times t = t.

monomial times a trinomial = another trinomial.

step-by-step explanation:

step 1: solve one of the equations for one of the variables. let's solve the first equation for y:

step 2: substitute that equation into the other equation, and solve for x.

step 3: substitute x = 4 x = 4 x=4 into one of the original equations, and solve for y.
