A tree grow 1/4 foot in 1/12 year.

lilavasa [31]

Answer:

Part A) The rate is $\frac{12}{4}\ \frac{feet}{years}$

Part B) In 1 year the tree grows 3 feet

Step-by-step explanation:

Part A) write the rate at which this tree grows as a fractions

we know that

To find out the rate at which the tree grows divide 1/4 foot by 1/12 year

$\frac{(1/4)}{(1/12)}=\frac{12}{4}\ \frac{feet}{years}$

Part B) how many feet does the tree grow in 1 year?

we know that

The tree grows at rate of $\frac{12}{4}\ \frac{feet}{years}$

Simplify

$\frac{3}{1}\ \frac{feet}{year}$

That means ----> The tree grows 3 ft in 1 year

therefore

In 1 year the tree grows 3 feet

The sum of two numbers is 8, and their difference is 22

lawyer [7]

Answer:

15, -7 x=15 y=-7

Step-by-step explanation:

x+y=8, we'll come back to this

x-y=22, move y to the other side, x=y+22

now insert the value of x =(y+22) to the other equation like so, (y+22)+y=8, simplify

2y+22=8 2y=(-14), y=(-7)

Insert the value of y into the first equation again like so, x+(-7)=8, simplify

x=15
