50
You can write that into an equation which is 0.64x=32 and if you divide 32 by 0.64 the answer is 50, and if you need to check that just multiply 50 by 0.64 and it equals 32

Solve the system of equations.

morpeh [17]

Answer:

y=3,x=1.3,z=6.2 :)

Step-by-step explanation:

y=3,x=1.3,z=6.2 :)

So, we have:

: x+y+z=10 [equation 1]

: 5x+3y=14 [equation 2]

: x−2y+z=2.5 [equation3]

(I'm going to assume that you know how to solve equations with 2 variables)

1. eliminate a variable to get 2 variables

Let's reverse equation 2:

-x+2y-z= -2.5

and take equation 1, to try to eliminate "z"

x+y+z=10

add up the 2 equations to get:

3y=7.5

and solve to get

y=2.5

2. substitute what we already solved into another equation

Luckily, equation 2 only has 2 variables, and one is y, so we can sub it in.

5x+3y=14 --> 3x+3(7.5)=14

solve to get

x=1.3

3. Substitute both of our variables in to get the final variable: z

Let's take the first equation.

x+y+z=10 --> 1.3+2.5+z=10

solve to get

z=6.2

I hope this helps you!

In 2010, the continent of South America had a population of 395, 280, 204 Which of the following is the closest estimate of this

lesya [120]

Given:

The population of continent of South America in 2010 is 395, 280, 204.

To find:

The closest estimate of this number.

Solution:

We have,

$Population = 395, 280, 204$

The approximate value of this number is

$Population \approx 400, 000, 000$

The scientific form of this value is

$Population = 4\times 10^8$

Therefore, the correct option is C.

The sides of a regular 9-sided polygon have been

Maksim231197 [3]

Answer:

x = 100°

Step-by-step explanation:

As the given shape is a regular polygon, the triangles created by extending the sides are <u>isosceles triangles</u>.

To calculate the base angles of the isosceles triangle, find the interior angle of the regular polygon:

$\textsf{Interior angle of a regular polygon} = \dfrac{180^{\circ}(n-2)}{n}$

$\textsf{(where }n \textsf{ is the number of sides)}$

Therefore:

$\textsf{Interior angle of a regular nonagon} = \dfrac{180^{\circ}(9-2)}{9}=140^{\circ}$

As angles on a straight line sum to 180°, the <u>base angle</u> of the isosceles triangle is:

= 180° - interior angle

= 180° - 140°

= 40°

Interior angles of a triangle sum to 180°.

⇒ 2 base angles + x = 180°

⇒ 2 × 40° + x = 180°

⇒ 80° + x = 180°

⇒ x = 180° - 80°

⇒ x = 100°
