Sushil was thinking of a number. Sushil divides by 7 then adds 7 to get an answer of 12. Form an equation

Let's assume the number Sushil was thinking was 'x'

Now lets understand each part,

First, Sushil divides the number by 7, writing this in numbers will give,

\frac{x}{7}

Sushil then adds 7 to digit, this will give

\frac{x}{7}+7

Sushil tells that the answer for the following equation is 12, so

\frac{x}{7} + 7 = 12

Therefore the equation Sushil made is \frac{x}{7} + 7 = 12

Happy to help :)

The number is 35.

35 divided by 7 is 5, and 5 plus 7 is 12.

What is 7•8+1•40. Explain your answer
zaharov [31]

Answer:

96

Step-by-step explanation:

We will use the order of operations to solve the equation

7×8+1×40

multiplication before addition, so we do this first:

7×8=56

We change the equation to this:

56+1×40

Then we multiply:

1×40=40

We change the equation to this:

56+40

Then we add to solve:

56+40=96

Find the real solution(s) of the equation. Round your answer to two decimal places when appropriate. 5x^6=30
Elina [12.6K]

Answer:

The real solutions are

x=\sqrt[6]{6}\approx 1.35\\\\\:x=-\sqrt[6]{6}\approx -1.35

Step-by-step explanation:

The solution, or root, of an equation is any value or set of values that can be substituted into the equation to make it a true statement.

To find the real solutions of the equation 5x^6=30:

\mathrm{Divide\:both\:sides\:by\:}5\\\\\frac{5x^6}{5}=\frac{30}{5}\\\\\mathrm{Simplify}\\\\x^6=6\\\\\mathrm{For\:}x^n=f\left(a\right)\mathrm{,\:n\:is\:even,\:the\:solutions\:are\:}x=\sqrt[n]{f\left(a\right)},\:-\sqrt[n]{f\left(a\right)}\\\\x=\sqrt[6]{6}\approx 1.35\\\\\:x=-\sqrt[6]{6}\approx -1.35

Find the inverse of the function y = x2 – 12
vivado [14]

Answer: y=\sqrt{x+12}

Step-by-step explanation:

I hope you mean y = x² - 12 and not y = 2x - 12.

You switch the y and x variables:

x = y² - 12

And solve for y:

x + 12 = y²

y=\sqrt{x+12}
