Noah is solving the inequality 7x + 5 > 2x + 35. First, he solves the equation 7x + 5 = 2x + 35 and gets x = 6.

How does the solution to the equation 7x + 5 = 2x + 35 help Noah solve the inequality 7x + 5 > 2x + 35? Explain your reasoning.

Inequalities are used to relate unequal expressions.

The solution to the inequality is:

The inequality is given as:

When Noah solved the inequality, he expressed the inequality sign ( > ) as =

So, we have:

The solution is:

Notice that the sign in the original expression is >

So, Noah needs to convert the = sign back to the original sign of the inequality i.e. >

Hence, the solution to the inequality is:

Step-by-step explanation:

7x+5>2x+35

5x>30

x>6

c.

step-by-step explanation:

she should of added 9^2 and 12^2. that is because it is a^2+b^2=c^2. c^2 is the hypotenuse and should always be bigger than the other two numbers. which is why she should of added 9 squared and 12 squared together instead of 15 squared.
