Answer:

<h2>-4/3</h2><h2 />

Step-by-step explanation:

4x + 3y = 9 ⇔ 3y = 9 - 4x ⇔ y = -4/3x + 3 then the slope of our line is -4/3

Then any line parallel to the line 4x + 3y = 9 must have a slope of -4/3.

weqwewe [10]

133 adult tickets were sold.

Step-by-step explanation:

Given,

Total tickets sold for school play = 399

Let,

x represent the number of children tickets sold.

y represent the number of adult tickets sold.

According to given statement;

x+y=399      Eqn 1

x = 2y           Eqn 2

Putting value of x from Eqn 2 in Eqn 1

2y+y=399\\3y=399

Dividing both sides by 3

\frac{3y}{3}=\frac{399}{3}\\y=133

133 adult tickets were sold.

elena-14-01-66 [18.8K]

Answer:

225 minutes or 3 hours and 45 minutes

Step-by-step explanation:

45 (minutes per day) times 5 (days in a school week) = 225 minutes

or add 45 (minutes per day)+ 45+45+45+45 = 225

To get the hours:

Divide 225 by 60 (minutes per hour) and it is 3 - remainder 45.
