Answer:

x = 6

Step-by-step explanation:

The equation to solve is:

$log_{x}36 = 2$

We can convert it to exponential form and find the answer. Below we show log to exponential form formula:

$log_{x}a=b\\x^b=a$

Now, we convert the log to exponential:

$log_{x}36 = 2\\x^2=36$

We now solve for "x",

$x^2=36\\x=+-\sqrt{36}\\x=6,-6$

We know the base number of log cannot be negative, so we disregard x = -6 and take x = 6 as our answer

Krystal’s poster project for reading class is 2 feet high and 1 1 2 feet wide. Her friend Victoria’s poster is 4 feet high and 1

Bess [88]

The area of Victoria's poster is twice the area of Krystal's poster.

<h3>How compare the areas of two similar posters</h3>

The two areas are shown in the image attached below. Each poster represents a rectangle and the ratio between the two areas ( $r_{A}$ ), no unit, is defined by the following formula:

$r_{A} = \frac{w_{V}\cdot h_{V}}{w_{K}\cdot h_{K}}$ (1)

Where:

$w_{V}$ - Width of Victoria's poster, in feet.
$h_{V}$ - Height of Victoria's poster, in feet.
$w_{K}$ - Width of Krystal's poster, in feet.
$h_{K}$ - Height of Krystal's poster, in feet.

If we know that $h_{V} = 4\,ft$ , $w_{V} = 1.5\,ft$ , $h_{K} = 2\,ft$ and $w_{K} = 1.5\,ft$ , then the ratio between the two areas is:

$r_{A} = \frac{(4)\cdot (1.5)}{(2)\cdot (1.5)}$

$r_{A} = 2$

The area of Victoria's poster is twice the area of Krystal's poster. $\blacksquare$

How to solve equations

stich3 [128]

Here are some things you should know when solving algebraic equations.

If you add an expression to both sides of an equation, the resulting equation will have the same solution set as the original equation. In other words, they will be equivalent. This is true for all operations. As long both sides are treated the same, the equation will stay balanced.

You will also need to know how to combine like terms. But what are like terms to begin with? Like terms are defined as two terms having the same variable(s) (or lack thereof) and are raised to the same power. In mathematics, something raised to the first power stays the same. So, 5x and 10x are like terms because they both have the same variable and are raised to the first power. You don’t see the exponents because it doesn’t change the value of the terms.

To combine like terms, simplify add the coefficients and keep the common variable(s) and exponent.

The distributive property is another important rule you will need to understand.

The distributive property is used mostly for simplifying parentheses in expressions/equations.

For example, how would you get rid of the parentheses here?

6(x + 1)

If there wasn’t an unknown in between the parentheses, you could just add then multiply. That is what the distributive property solves.
The distributive property states that a(b + c) = ab + ac
So, now we can simplify our expression.

6(x + 1) = 6x + 6

One 6 oz juice box has 90 calories. How many calories are there in 64 oz jug of the juice? Round to the nearest calorie.

Aleonysh [2.5K]

Answer:

960 calories for the 64 oz jug

Step-by-step explanation:

6 oz for 90 calories.

64 oz for ??? calories.

It's a ratio, 6:90

and 64:???

so 6 * 10 2/3 is 64.

so 90 * 10 2/3 is ???

960 is ???
