What is the value of x in the equation 8x – 2y = 48, when y = 4?

Hey there!

So, if y=(4), this would mean that we would do (2 \ * \ 4) and from this, we would get 8. 

We will then need to find what is (x).

(x) = 7

8*7 = \boxed{56}

So, the equation would really look like . . .

\left[\begin{array}{ccc} 8*(7)-2*4 = 48 \\ \\ x=\boxed{7}\end{array}\right]

Hope this helps.

David made a class banner out of a large rectangular piece of paper. He
spin [16.1K]

<u>Given:</u>

A triangular piece is cut out of a rectangular piece of paper to make the class banner.

<u>To find:</u>

The area of the class banner.

<u>Solution:</u>

The rectangular piece of paper is 14 inches long and 5+3=8 inches wide.

From the given diagram, the triangle has a base length of the same 8 inches and has a height of 14-11=3 inches long.

To determine the area of the banner, we subtract the area of the triangle from the area of the rectangle.

The area of a triangle = \frac{1}{2} (b)(h).

The area of the triangle = \frac{1}{2} (8)(3) = 12 square inches.

The area of a rectangle = (l)(w).

The area of the rectangle = (14)(8)= 112 square inches.

The area of the class banner = 112-12=100 square inches.

So the banner has an area of 100 square inches which is the first option.

Use the rules of exponents to simplify the expressions. Place a final answer in fraction form. (-1/2)to the power of 3 *(-1/2) t
Pavlova-9 [17]

Answer:

-1/32

Step-by-step explanation:

we have

(-\frac{1}{2})^{3} )(-\frac{1}{2})^{2})

Remember that

The exponent "product rule" tells us that, when multiplying two powers that have the same base, you can add the exponents

so

(-\frac{1}{2})^{3} )(-\frac{1}{2})^{2})=(-\frac{1}{2})^{3+2})=(-\frac{1}{2})^{5})=-\frac{1}{32}

you deposited $5500 in a account that pays 3.6% annual interest. find the balance after 2 years if the interest is compound mont
Sedaia [141]

Answer:

$5,909.97

Step-by-step explanation:

We will use the compound interest formula for this problem as shown below:

A=P(1+\frac{r}{n} )^{nt}

<em>P = initial balance</em>

<em>r = interest rate (decimal)</em>

<em>n = number of times compounded annually</em>

<em>t = time</em>

<em />

First, change 3.6% into a decimal:

3.6% -> \frac{3.6}{100} -> 0.036

Now plug in the values:

A=5,500(1+\frac{0.036}{12})^{12(2)}

A=5,909.97

After 2 years, the balance would be $5,909.97

Find the value of the variable. If your answer is not an integer, leave it in simplest radical form.
AlekseyPX

Answer:

$\frac{5\sqrt{2} }{2}$

Step-by-step explanation:

x: \text{opposite side of the angle of 45\º}

5: \text{hypotenuse of the right triangle}

$\sin(\theta)=\frac{\text{opp}}{\text{hyp}} \Rightarrow \sin(45\º)=\frac{x}{5} $

$\text{Once }\sin(45\º)=\frac{\sqrt{2} }{2} $

$\frac{\sqrt{2} }{2} =\frac{x}{5} \Rightarrow 2x=5\sqrt{2} \Rightarrow x=\frac{5\sqrt{2} }{2}  $

You can just remember that 5 is the diagonal of a square of side length x.

$5=x\sqrt{2} \Rightarrow x=\frac{5}{\sqrt{2} } \Rightarrow x=\frac{5}{\sqrt{2} } \cdot \frac{\sqrt{2} }{\sqrt{2} } = \frac{5\sqrt{2} }{2} $
