If a basketball player consistently shoots 80% from the free throw line and she takes 25 free throw shots throughout the course
faltersainse [42]
The formula for percentage is:

is/of = %/100

In the given problem,
is = ?
of = 25
% = 80

We get,

?/25 = 80/100

"is" is unknown so let "is" be "x"

x/25 = 80/100

We have to cross multiply.  Meaning, we will multiply the numerator of one fraction by the denominator of the other fraction. Therefore,

100x = (80)(25)
100x = 2000
x = 20

The answer is 20.  The basketball player is expected to make 20 free throw shots out of 25 in the entire game.

James is running late to his cousin's wedding and drives the 45 miles between his house and the wedding location 20 miles per ho
netineya [11]

Answer:

(r + 20)t = r

Step-by-step explanation:

Distance is constant in the scenario above, distance from home to wedding and wedding back home is the same.

From wedding back home. :

Recall : Distance = speed * time

Distance = r * 1 hour

From home to wedding :

Speed = 20 mph more ; r + 20

Time = t

Distance = (r + 20)* t = (r +20)t

Since the distance are the same, we can equate both :

(r + 20)t = r * 1

= (r + 20)t = r
