Answer:

x = 8

Step-by-step explanation:

Your last step would be division property so, you take 3 and divide it from 3x and 24, and because you do that, it cancels out the three, and you end up getting x = 8. Because 24 divided by 3 equals 8.

Raymond has $800 in a savings account that earns 10% interest per year.The interest is not compounded. How Much Interest Will He

Gennadij [26K]

The amount of interest he would earn in one (1) year is equal to $80.

Given the following data:

Interest rate = 10% = 0.1

Principal = $800

Time = 1 year

To determine how much interest he would earn in one (1) year:

<h3>How to calculate simple interest</h3>

Mathematically, simple interest is given by this formula:

$I = PRT$

Where:

S.I is the simple interest.

P is the principal or starting amount.

R is the interest rate.

T is the time measured in years.

Substituting the given parameters into the formula, we have;

$I=800 \times 0.1 \times 1$

Simple interest = $80

Triangle J K L is shown. Angle J K L is 120 degrees and angle K L J is 40 degrees. The length of K L is 2 and the length of J L

Veseljchak [2.6K]

Answer:

$k \approx 5$ units$

Step-by-step explanation:

In Triangle JKL

$\angle K=120^\circ\\\angle L=40^\circ\\KL=2\\JL=k$

We want to determine the approximate value of k using the law of sines.

$\angle J+\angle K+\angle L=180^\circ $ (Sum of angles in a \triangle)\\\angle J+120^\circ+40^\circ=180^\circ \\\angle J=180^\circ-(120^\circ+40^\circ)=20^\circ$

Using Law of Sines

$\dfrac{k}{\sin K} =\dfrac{j}{\sin J} \\\dfrac{k}{\sin 120} =\dfrac{2}{\sin 20} \\k=\sin 120 \times \dfrac{2}{\sin 20}\\k=5.06\\k \approx 5$ units$
