Answer:

Step-by-step explanation:

x is the number of weeks

a) Ms. Smith = 14 + 4x

Mr Smith = 20 + 2x

b) 14 + 4x = 20 + 2x

4x - 2x = 20 - 14

2x = 6

x =3

three weeks

c)

Ms. Smith = 14 + 4x = 14 + 4(3) = 26

Mr Smith = 20 + 2x = 20 + 2(3) = 26

The equation which represent number of days is 87 ÷ n = 3

<h3>What is Division?</h3>

It is the inverse of the multiplication operation. It is defined as the act of forming equal groups. While dividing numbers, we break down a larger number into smaller numbers such that the multiplication of those smaller numbers will be equal to the larger number taken.

Here,

total hour practicing = 87 hours

Daily hours for practicing = 3 hours

total number of days = n days

Now, according to question;

n X 3 = 87

87 ÷ n = 3

Thus, the equation which represent number of days is 87 ÷ n = 3.

A student solved the problem below by first dividing 20 by 10. What mistake did the student make?
Dennis_Churaev [7]

Answer:

around 66% of their games

Step-by-step explanation:

So if we add 20 and 10 we get 30 which is the total amount of games played. We know that the team won 20 of the 30 games which we can reduce to 2/3. 2/3 is equal to 66.66 but most people just say 66% or you can round it up to 67%

Hope I helped!
