4x + 4y = 12
-2x + y = -3

Answers

Answer 1
Answer:

(9/4, 3/4)

Explanation:

4x + 4y = 12
2(-2x + y = -3)

4x + 4y = 12
-4x + 4y = -6

8y = 6

y = 3/4


4x + 4(3/4) = 12

4x + 3 = 12

4x = 9

x = 9/4

a person walks 1/5 mile in 1/15 hour the person speed is what miles per hour

Answers

Answer:

(1/5 mi) / (1/15 hr) = 1/5 * 15/1 = 3 mi/hr

Step-by-step explanation:

The speed of the person will be equal to 3 mi/hr.

What is speed?

Speed is defined as the ratio of the time distance traveled by the body to the time taken by the body to cover the distance. Speed is the ratio of the distance traveled by time. The unit of speed in miles per hour.

Given that a person walks 1/5 mile in 1/15 hour. The speed of the person will be calculated as,

Speed = (1/5 mi) / (1/15 hr)

Speed = 1/5 x 15/1

Speed = 3 mi/hr

Therefore, the speed of the person will be equal to 3 mi/hr.

An object is traveling at a steady speed of 9 9/10 km/per hour about how long will it take the object to travel 5/1/10 km/per hour.

Answers

Answer:

0.52 km

Step-by-step explanation:

We are given that

Speed of object, v=[tex]9\frac{9}{10}km/h[/tex]

Speed of object, v=[tex]9+0.9=9.9km/h[/tex]

Distance travel by object, s=[tex]5\frac{1}{10}km[/tex]

Distance travel by object, s=[tex]5+0.1=5.1km[/tex]

We have to find the time taken by object to travel 5 1/10 km.

We know that

[tex]Time=\frac{Distance}{speed}[/tex]

Using the formula

Time taken by object to travel 5.1 km =[tex]\frac{5.1}{9.9} hr[/tex]

Time taken by object to travel 5.1 km=0.52 hr

I need help on knowing whether this is a solvable equation. Along with reasons why. HELP IF YOU CAN :))

Answers

To check if x = 9 is the solution, we need to replace every x with 9 and simplify

(3+x)/4 = 3

(3+9)/4 = 3

12/4 = 3

3 = 3

We get the same thing on both sides, so the last equation is a true equation. This means that the first equation is a true equation when x = 9. Therefore, the solution x = 9 is confirmed.

Find the measure of interior angle C of hexagon OCEANS in which the
measure of the interior angles are:
O: 3x + 15, C: 2x + 30, E: 5x + 10, A: 2x + 55, N: 2x + 60, and S: x - 35.

Answers

Answer:

The measure of the interior angle C is [tex]108^{o}[/tex].

Step-by-step explanation:

Sum of angles in a polygon = (n - 2) x 180

where n is the number of sides of the polygon.

For a hexagon, n = 6. So that;

Sum of angles in a hexagon = (6 - 2) x 180

                                     = 4 x 180

                                     = [tex]720^{o}[/tex]

Sum of angles in a hexagon = [tex]720^{o}[/tex]

⇒ 3x + 15 + 2x + 30 + 5x + 10 + 2x + 55 + 2x + 60 + x - 35 = [tex]720^{o}[/tex]

15x + 135 = [tex]720^{o}[/tex]

15x = [tex]720^{o}[/tex] - 135

15x = 585

x = [tex]\frac{585}{15}[/tex]

  = [tex]39^{o}[/tex]

But,

C = 2x + 30

   = 2(39) + 30

   = 78 + 30

   = [tex]108^{o}[/tex]

The measure of the interior angle C is [tex]108^{o}[/tex].

GEOMETRY!!!! pls help (also pls explain)

Answers

We have an angle and an adjacent side, and we are looking for an opposite side. Because we have adjacent and opposite, that tells us that we need to use tangent.

10 * tan(31) = 6.008, when rounded to the nearest tenth you would just say 6.

To answer this question, you need trigonometry.

Are you familiar with the chant soh cah toa?

In here, you can see that the side you have is adjacent to the angle you have, and you're trying to find the opposite side. This means you need tangent = opposite ÷ adjacent

If the angle was 30° 45° or 60° Then there is a table you can use to calculate, but there isn't so just use a calculator

tan 31° = x ÷ 10

C
There is no solution

Answer:

C. There is no solution.

Step-by-step explanation:

First, multiply what in the parentheses by what's outside of them.

[tex]2(x - 3) = 2x + 5 ↴[/tex]

[tex]2x - 6 = 2x + 5 [/tex]

Then seperate variables from nonvariables. After subtracting [tex]2x[/tex] from the right and left side, the equation becomes this:

[tex] - 6 = 5[/tex]

This equation has no solutions because this is an inequality.
