7 0

Answer:

The answer is 28.

Step-by-step explanation:

Ok.

☆7x and 3x + 16 are congruent, meaning they equal the same.

☆Since they are equal, we can make an equation out of then.

7x = 3x + 16

☆Then we just solve.

\:  \:  \:  \:  \:  \:  \:  \:  \: 7x = 3x + 16 \\   \frac{- 3x =  - 3x}{4x = 16}  \\  \\  \frac{4x}{4}  =  \frac{16}{4}  \\  \\ x = 4

☆Therefore, x equals 4.

☆We are solving for m<KJL so all we need to do is plug in.

7x \\ 7(4) \\ 28

☆You answer is 28.

You deposit $3000 into a money-market savings account which pays 4.8% compounded quarterly, and you make no withdrawals from or
faust18 [17]

Answer:

$5265.71

Step-by-step explanation:

We have been given that you deposit $3000 into a money-market savings account which pays 4.8% compounded quarterly.

We will use future value formula to solve our given problem.

FV=C_0\times (1+r)^n, where,

C_0=\text{Initial amount},

r = Rate of return in decimal form,

n = Number of periods.

4.8\%=\frac{4.8}{100}=0.048

n=3\times 4=12

FV=\$3,000\times (1+0.048)^{12}

FV=\$3,000\times (1.048)^{12}

FV=\$3,000\times 1.7552354909370114

FV=\$5265.7064\approx \$5265.71

Therefore, there will be $5265.71 in your account at the end of those 3 years.

The area of a square garden is 1/36 mi 2 how long is each side<br><br>​
Vitek1552 [10]

Answer:

1/6 meters

Step-by-step explanation:

Let the side length be x.

Then the area of the square = x^2

∴ x^2 = 1/36

√(x^2) = √(1^2 / 6^2)

x        = 1/6

Therefore, the side length is 1/6 meters.

Hope it helped you!!!
