\text {Hi There! Let's Solve this Problem!}

\text {\underline {The First Step is to Simplify}}

\text {2*x=2x}\\\text {2*5=10}

\text {Your New Problem Is: 2x+10=x-4}

\text {\underline {The Next Step is to Subtract x}}

\text {2x+10-x=x-4-x}

\text {Your New Problem Is: x+10=-4}

\text {\underline {The Final Step is to Subtract 10}}

\text {x+10-10 (Crosses Out)}\\\text {-4-10}

\text {Your Answer Would Be:}

\Huge\boxed {x=-14}

\text {Best of Luck!}

Answer:

Step-by-step explanation:

Here you go mate

Use PEMDAS

Parenthesis,Exponent,Multiplication,Division,Addition,Subtraction

Step 1

2(x+5)=(x-4)  Equation/Question

Step 2

2(x+5)=(x-4)  Remove parenthesis

2x+10=x-4

Step 3

2x+10=x-4  Subtract 1x from sides

x+10=-4

Step 4

x+10=-4  Subtract 10 from sides

answer

x=-14

Identify the values of the variables. Give your answers in the simplest radical form.
Lena [83]

Answer/Step-by-step explanation:

✔️Find k:

Reference angle = 60°

Hypotenuse = k

Opposite = 9

Therefore, using trigonometric ratio, we have:

sin(60) = \frac{9}{k}

Multiply both sides by k

k*sin(60) = 9

Divide both sides by sin(60)

k = \frac{9}{sin(60)}

k = \frac{9}{\frac{\sqrt{3}}{2}}

k = 9*\frac{2}{\sqrt{3}}

k = \frac{18}{\sqrt{3}}

Rationalize

k = \frac{18*\sqrt{3}}{\sqrt{3}*\sqrt{3}}

k = \frac{18\sqrt{3}}{3}

k = 6\sqrt{3}

✔️Find f:

Reference angle = 60°

Opposite = 9

Adjacent = f

Therefore, using trigonometric ratio, we have:

tan(60) = \frac{9}{f}

Multiply both sides by f

f*tan(60) = 9

Divide both sides by tan(60)

f = \frac{9}{tan(60)}

k = \frac{9}{\sqrt{3}}

Rationalize

k = \frac{9*\sqrt{3}}{\sqrt{3}*\sqrt{3}}

k = \frac{9\sqrt{3}}{3}

k = 3\sqrt{3}

the average salary for new college graduates with the job is $50,556. A particular University wants to claim his graduates earn
ValentinkaMS [17]

Answer:

Given:

Null hypothesis: the average salary for new college graduates with a job is $50,556.

Alternative hypothesis: the graduates from a university earn more than that average.

Using the z-test:

=> Calculate the value of test statistic:

t = (mean of sample - mean of null hypothesis)/(std/sqrt(number of sample)

 = (53200 - 50556)/(10200/sqrt(100))

 = 2.592 > 1.645

=> Reject the null hypothesis, their graduates earn more than average

Hope this helps!

Find the slope and equation of a line perpendicular to the y axis that passes through (3,-8)
alexgriva [62]

A line perpendicular to the y axis is horizontal line (parallel to the x axis).

Equation of this line is y = a.

The line passes through (3, -8) → x = 3 and y = -8.

Therefore your answer is y = -8.

Answer:

$39

Step-by-step explanation:

He has $115 total, and he spent it on shirts and pants
