The sum of the inside angles of a 6 sides figure is 720

Add the known angles together:

90 + 112 + 131 + 154 + 118 = 605

Subtract the sum of the known angles from 720 for x:

x = 720 - 605 = 115

x = 115 degrees.

Answer:

The sum of the interior angles of the hexagon is 720°

$x + 154 + 131 + 112 + 90 + 118 = 720 \\ x + 605 = 720 \\ x = 720 - 605 \\ \boxed{x = 115}$

<h3>x= 115° is the right answer.</h3>

2.5x - 3 + 2x = 1.75x - 1.25x + 13

4.5x - 3 = 0.50x + 13

4.0x = 16

x = 4

Answer: 4

2. We'll assume those xs are in the numerator

(3/7)x - 1/4 + (3/7)x = (9/7)x - (3/7)x + 3/4 - 1

(6/7)x - 1/4 = (6/7)x - 1/4

0 = 0

That's always true.

Answer: Any x is a solution.

Help me please?? solve using proportion

Answer:

2 1/2 cups

Step-by-step explanation:

A proportion says the ratio of one thing to another is the same for different amounts. Here, we want cups, so we can use the proportion ...

cups/people = 2/12 = x/15 . . . . . where x is the number we want to find

Multiplying by 15 gives ...

x = 15(2/12) = 5/2 = 2 1/2

You will need 2 1/2 cups of zucchini to feed 15 people with the same recipe.

Which expression is eq to (125^2/125^4/3)

sweet [91]

Answer:

Step-by-step explanation:

So the denominator can be simplified to 5⁴ → $(5^3)^\frac{4}{3}$ and then the 3's cancel out and we are left with 5⁴

Now our new fraction is $\frac{125^{2} }{5^{4} } = \frac{15625}{625}$ which then simplifies to 25

A bowl contains 4 red marbles and 3 yellow marbles. Tim randomly draws 3 red marbles from the bowl. He replaces each marble afte

mr Goodwill [35]

So,

The probability of drawing a yellow marble is $\frac{3}{7}$ .
Since he replaces the marble after it is drawn out, the probability of drawing another yellow is the same: $\frac{3}{7}$ .

The probability of drawing a red marble is $\frac{4}{7}$ .

In order to get the probability of drawing 2 yellow marbles and 1 red marble, given that each marble is replaced after it is drawn out, we must multiply the fractions together.

$( \frac{3}{7} )( \frac{3}{7} )( \frac{4}{7} ) = \frac{36}{343}$

Because the order of the marbles doesn't matter, we will multiply the probability by 3.
$3( \frac{36}{343} ) = \frac{108}{343}$
