To find the amount you must multiply percentage by the original number. The correct answer would be $162

540 * .30 is 162 so it would be $162.

Which number line represents the solution set for the inequality 2x – 6 ≥ 6(x – 2) + 8?

vovangra [49]

Answer: x≤ -0.5

Step-by-step explanation: Graph the two lines or solve for x:

2x – 6 ≥ 6(x – 2) + 8

2x – 6 ≥ 6x – 12 + 8

2x – 6 ≥ 6x – 4

-4x ≥ 2

x ≤ -1/2 [Inequality is reversed when multiplying or dividing by a negative number]

The number line is anything less than or equal to - 1/2

Or one can plot each side of the inequality and note the interception point (x = -(1/2)).

If (a+10) and (a+20)are supplementary angles,find them

motikmotik

Given:

(a+10) and (a+20) are supplementary

To find:

Each angle

Steps:

if 2 angles are supplementary that means they add up to 180°

(a + 10) + (a + 20) = 180

a + 10 + a + 20 = 180

2a + 30 = 180

2a = 180 - 30

2a = 150

a = 150/2

a = 75°

Now let's find value of each angle,

a + 10 = 75 + 10

= 85°

a + 20 = 75 + 20

= 95°

Therefore, the value of each angle is 85° and 95° respectively

Happy to help :)

!30 POINTS! How can I use this trapezoid to prove the Pythagorean Theorem?

Ivanshal [37]

Answer:

a = a

b = b

c = c

Step-by-step explanation:

Formula: $a^2+b^2=c^2$

C is always the largest number

a times a + b times b = c times c
