Answer:

x<3

Step-by-step explanation:

2.40 + 2.20x < 9

move the constante to the right hand side and change its sign

2.2x<9-2.4

calculate: subtract the numbers 9-2.4

2.2x<6.6

Divide both sides of the inequality by 2.2

Which number belongs to the solution set of the equation below?

ollegr [7]

The correct answer would be: C. 44
Explanation: If you're trying to find out x's value, you have to do the inverse operation which means if it's subtraction, you add. So to find x's value, you'd add 36 + 8 = x. And 36 + 8 = 44. So therefore, x = 44. That means the answer is C.

6 more than twice a number is greater than negative sixteen

Alexxandr [17]

Writing the problem as an equation you have:

2x+6 > -16

Solve for x:

2x+6 > -16

Subtract 6 from each side:

2x > -22

Divide both sides by 2:

x > -11

The answer is: x > -11

The measures of the angles of a triangle are in the extended ratio 2:2:8. What is the measure of the smallest angle?

zepelin [54]

We know that the ratio is;

$2:2:8$

The angles in a triangle add up to give 180°

We can think of there being twelve "parts" that add up to 180°

$2x + 2x + 8x = 180 \\ \\ 12x = 180 \\ \\ x = \frac{180}{12} \\ \\ x = 15$

So our ratio is;

$2*15 : 2*15 : 8*15 \\ \\ = 30 : 30 :120$

So the smallest angle is 30°
