Jessie has a total of 36 coins of dimes and nickels. Total value is $2.35. How many of each kind of coins does he have?

Viktor [21]

There are 2 dollars so that would equal 20 dimes.

Proof:

10 cents = a dime

20 x 10 = 200 = 2 dollars

There are 35 cents to that would equal 3 dimes and 1 nickel.

Proof:

10 cents = a dime

5 cents = a nickel

3 x 10 = 30

1 x 5 = 5

So the final answer would be 23 dimes and 1 nickel.

Jim is enclosing a rectangular garden with 170 feet of fencing. The length of the garden is 10 feet more than twice it’s width,

Darina [25.2K]

Answer:

$1,500\ ft^2$

Step-by-step explanation:

Let

L ----> the length of the rectangular garden in feet

w ---> the width of the rectangular garden in feet

step 1

Find the width

we know that

The perimeter of the rectangular garden is

$P=2(L+W)$

$P=170\ ft$

$170=2(L+W)$

Simplify

$85=(L+W)$ ----> equation A

$L=2W+10$ ----> equation B

substitute equation B in equation A and solve for W

$85=(2W+10+W)$

$85-10=3W$

$3W=75$

$W=25\ ft$

Find the value of L

$L=2(25)+10=60\ ft$

step 2

Find the area

we know that

The area of the rectangular garden is

$A=(LW)$

substitute the values

$A=(60)(25)=1,500\ ft^2$
