Explain how to convert percent to fractions and percents and decimals

mars1129 [50]

Percents to a decimal is easier to understand just take the percent so say it is 35% the decimal form would be .35 or 5% .05, and for the percent to a fraction just take the percent such as 30/100 and make sure it is in the simplest form to solve so that would be 3/10.

Find the equation of the linear function represented by the table below in slope-intercept form.Answer: ?(Important: Please chec

Salsk061 [2.6K]

The Slope-Intercept form of the equation of the line is:

$y=mx+b$

Where "m" is the slope of the line and "b" is the y-intercept.

The slope can be found with:

$m=\frac{y_2-y_1}{x_2-x_1}$

Choose two points from the table. These could be the points (1,-4) and (4,-19). You can set up that:

$\begin{gathered} y_2=-19 \\ y_1=-4 \\ x_2=4 \\ x_1=1 \end{gathered}$

Substituting values, you get that the slope of this line is:

$m=\frac{-19-(-4)}{4-1}=-5$

You can substitute the slope and the first point into the equation in Slope-Intercept form:

$-4=1(-5)+b$

Solve for "b":

$\begin{gathered} -4+5=b \\ b=1 \end{gathered}$

Therefore, the Equation of this line in Slope-Intercept form is:

$y=-5x+1$

A square wrestling mat has a perimeter of (12x-32) feet. Write an expression in simplest form that represents the side length (

docker41 [41]

Answer:

3x-8

Step-by-step explanation:

The perimeter of the wrestling mat is

$P=12x-32$

Since the mat is square-shaped, all of its sides have the same length L and the perimeter is 4L, so to find the length of the side we have to divide by 4

$L=\frac{12x-32}{4}=3x-8\ feet$

What is the value of x in the equation three-fourths (one-fourth x 8) minus (one-half x 2) = startfraction 3 over 8 endfraction

Oksi-84 [34.3K]

The value of x in the equation is x=-44.

The given equation is $\frac{3}{4}\left(\frac{1}{4}x+8\right)-\left(\frac{1}{2}x+2\right)=\frac{3}{8}(4-x)-\frac{1}{4}$ .

An algebraic expression in mathematics is an expression that's made from variables and constants, together with algebraic operations (addition, subtraction, etc.). Expressions are made of terms.

Firstly, apply the distributive property as a(b+c)=ab+ac and get

$\begin{aligned}\frac{3}{4}\times \frac{1}{4}x+\frac{3}{4}\times 8-\frac{1}{2}x-2&=\frac{3}{8}\times 4-\frac{3}{8}\times x-\frac{1}{4}\\ \frac{3x}{16}+6-\frac{x}{2}-2&=\frac{3}{2}-\frac{3x}{8}-\frac{1}{4} \end$

Now, rearrange the terms by taking variable terms on the left-hand side and constant terms on the right-hand side as

$\frac{3x}{16}-\frac{x}{2}+\frac{3x}{8}=\frac{3}{2}-\frac{1}{4}-6+2$

Further, simplify the above expression by taking L.C.M as

$\begin{aligned}\frac{3x-8x+6x}{16}&=\frac{6-1}{4}-4\\ \frac{x}{16}&=\frac{5-16}{4}\\ \frac{x}{16}&=\frac{-11}{4}\end$

Then, multiply both sides with 4 and get

$\begin{aligned}4\times \frac{x}{16}&=4\times \frac{-11}{4}\\ \frac{x}{4}&=\frac{-11}{1}\end$

Furthermore, cross multiply both sides and get

$x=-44$

Hence, the value of x in the equation which is given $\frac{3}{4}\left(\frac{1}{4}x+8\right)-\left(\frac{1}{2}x+2\right)=\frac{3}{8}(4-x)-\frac{1}{4}$ is x=-44.
