Solve and graph: 7x-6>22 (pls explain your answer, im confused on this)

Answer:

x>4

Step-by-step explanation:

Solving an inequality is very similar to solving an equation:

Given: 7x-6>22

Add 6 to both sides: 7x>28

Divide both side by 7: x>4

x>4 means that all x-values that are greater than 4 will work. Therefore you would write an open dot at x=4 on the number line to show that 4 isn't included, and draw an arrow going right to show all possible solutions greater than 4.

Answer: $\huge\boxed{\boxed{15}}$

Step-by-step explanation:

Given expression

$\large\boxed{\frac{12[30 - (9+4^2)]}{|10|-|-6| } }$

Simplify the exponents

$\large\boxed{=\frac{12[30 - (9+16)]}{|10|-|-6| } }$

Simplify values in the parenthesis

$\large\boxed{=\frac{12[30 - 25]}{|10|-|-6| } }$

$\large\boxed{=\frac{12[5]}{|10|-|-6| } }$

Simplify absolute values (all positive)

$\large\boxed{=\frac{12[5]}{10-6 } }$

$\large\boxed{=\frac{12[5]}{4 } }$

Simplify by division

$\large\boxed{=3~[5]}$

Simplify by multiplication

$\huge\boxed{\boxed{=15}}$

Hope this helps!! :)
