Solve the inequality 2c/3+1>7

beks73 [17]

Answer:

c > 9

Step-by-step explanation:

(2c/3) + 1 > 7 subtract 1 from both sides

2c/3 > 7 -1

2c/3 > 6 (multiply both sides by 3)

2c > 6(3)

2c>18 (divide both sides by 2)

c > 18 / 2

c > 9

Find the length of the unknown side. Round your answer to the nearest tenth.<br> 20 m<br> 12 m<br> b

stepladder [879]

The length of the unknown side is 16 meters

<h3>What is a right triangle?</h3>

A right triangle is a triangle that has one of its angles to be 90 degrees

The length of the unknown side is calculated using the following Pythagoras theorem.

$20^2 = 12^2 +b^2$

Evaluate the exponents

$400 = 144 +b^2$

Collect like terms

$b^2 = 400 -144$

Evaluate the like terms

$b^2 = 256$

Take the square root of both sides

$b = 16$

Hence, the length of the unknown side is 16 meters
