Wangari plants trees at a constant rate of 1212 trees every 33 hours. Write an equation that relates pp, the number of trees Wan
igor_vitrenko [27]

Answer:

p=4h    

Step-by-step explanation:

Let p be the number of trees Wangari plants, and h  be the time she spends planting them in hours.

We have been given that Wangari plants trees at a constant rate of 12 trees every 3 hours.    

Let us find number of trees planted in 1 hour by dividing 12 by 3.

\text{Number of trees planted in 1 hour}=\frac{12\text{ plants}}{3\text{ hour}}

\text{Number of trees planted in 1 hour}=4\frac{\text{ plants}}{\text{ hour}}

We can represent this information as: p=4h

Therefore, the equation p=4h relates the number of trees (p) Wangari plants, and the time (h) she spends planting them in hours.

Harlamova29_29 [7]

Answer:

7.5

Step-by-step explanation:

To solve this expression, we can use PEMDAS or order of operations.

<u>Parenthesis</u>

<u>Exponents</u>

<u>Multiplication>Division (Depends on which comes first from left to right)</u>

<u>Addition>Subtraction (See Multiplication>Division)</u>

So First, lets solve the <u>Parenthesis</u>. -2/5=-.4

So now, our equation is -3/-.4

There is no exponents or multiplication, so lets just <u>Divide</u>.

-3/-.4=7.5

The solution is 7.5

Hope this helps!
