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

$P=2(L+W)$

$P=170\ ft$

so

$170=2(L+W)$

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

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

5x-2x-1x=<br> A.4x<br> B.2x<br> C.8x <br> What is it

vaieri [72.5K]

Answer:

2x

Step-by-step explanation:

We can first pull the x out of every term:

$5x-2x-1x=x(5-2-1)$

Then, simplify:

$x(5-2-1) = x(2) = 2x$

So, the answer is 2x.

Jolene invests her savings in two bank accounts, one paying 4 percent and the other paying 10 percent simple interest per year.

Nostrana [21]

Answer:

<h2>$ 22200 in higher yielding bank and $ 44400 in lower yielding bank</h2>

Step-by-step explanation:

Jolene invests in two bank accounts. The first account gives a 4% interest per year and the second bank gives a 10% interest rate per year.

She puts twice as much in the lower yielding bank account. Let us denote the amount put in high yielding bank account by $x$ . Lower yielding bank account will have $2x$ .

$Interest\text{ }per\text{ }year=Principal\times Interest\text{ }rate$

Interest from lower yielding bank = $\dfrac{4}{100} \times 2x=\dfrac{8x}{100}$

Interest from higher yielding bank = $\dfrac{10}{100} \times x=\dfrac{10x}{100}$

Total Interest per year = $ 3996 = $\dfrac{8x}{100} +\dfrac{10x}{100}=\dfrac{18x}{100}$

$x=22200 \$$

∴ Jolene invested $ 22200 in higher yielding bank and $ 44400 in lower yielding bank.
