Answer:

X= 139

Step-by-step explanation:

1. Suplementary angle = 180 degrees

2. Set up the Equation  

  41 + x = 180

3. Solve

 41 + x = 180

-41           -41

       x = 139

Answer:

A) 70

Step-by-step explanation:

180 - 120 = 60

? = x

x + 50 + 60 = 180

x + 110 = 180

x = 70

Answer:

x = 16.64

option A

Step-by-step explanation:

Using the pythagoreom therom

Answer:

16.64

Step-by-step explanation:

Since it's a right angled triangle, we use Pythagoras theorem:

(Hypotenuse)² = (base)² + (perpendicular)²

x² = 14² + 9²

x² = 196 + 81

x² = 277

√x² = √277

x = 16.64

Answer:

x=-4/3, y=3/-5

Step-by-step explanation:

X+2X=-4

Then, adding up we get: 3x=-4

Then, x=-4/3

Substituting those we get: 3*(-4/3)-5y=-1

-4-5y=-1

-5y=-1+4=3

y=3/-5

Thus, x=-4/3, y=3/-5

All is in the picture

Step-by-step explanation:

Use TOA. (tan angle = opposite/adjacent)

Given angle A = 58

adjacent = 6 mi

[tex] \tan(a) = \frac{opposite}{adjacent} \\ \tan(58) = \frac{bc}{6} \\ bc = 6 \tan(58) \\ = 9.6mi(nearest \: tenth)[/tex]

Answer:

x=8 y=1

Step-by-step explanation:

you have first and second equation, YOU MUST FIND THE THIRD EQUATION

SOLUTION

FIND equation 3 from 2

x+2y=10

x=10-2y...........3

Substitute equation 3 from first (not from the equation where you got equation 3)

2 (10-2y)-7y=9

20-4y-7y=9

-11y=9-20

-11y= -11

-11y/-11= -11/-11

y=1

Find the value of x from the third equation

x=10-2 (1)

x=8

Answer:

AD = 230

Step-by-step explanation:

here, we want to find the measure it AD

To do this, we need the value of x firstly

To get this, we are going to use the trapezoid midpoint theorem

The theorem is that the sum of the two parallel sides of a trapezoid when divided by 2 will give the middle point length of the trapezoid

Applying this:

1/2{30x-10+ 30x + 28} = 31x + 1

2(31x + 1) = 60x+ 18

divide both sides by 2

31x + 1 = 30x + 9

31x -30x = 9-1

x = 8

But;

AD = 30x-10

AD = 30(8)-10

AD = 240-10

AD = 230

Answer:

14 installatons

42 service calls

Step-by-step explanation:

Let x = no. of new installations

      y = no. of service calls

(1)    x + y = 56           (2)    450x + 75y = 9450

            y = 56 - x               450x + 75(56 - x) = 9450

                                           450x + 4200 - 75x = 9450

                                            375x = 5250

                                                   x = 14 installatons

             y = 56 - 14 = 42 service calls

The number of installations are 14 and number of service calls are 42

Two or more expressions with an Equal sign is called as Equation.

Given,

An air-conditioning company counted 56 invoices at the end of the month.

For installation it charges  $450 and $75 for a service call.

Let x be number of installations

y be number of service calls

x+y=56...(1)

and 450x+75y=9450..(2)

From equation 1

x=56-y

Now substitute x value in equation 2

450(56-y)+75y=9450

Apply distributive property

25200-450y+75y=9450

25200-375y=9450

Subtract 25200 from both sides

-375y=9450-25200

-375y=-15750

Divide both sides by 375

y=42

Now put y value in equation 1

x+42=56

x=14

Hence, the number of installations are 14 and number of service calls are 42

I dont really know if this is right myself, but i'm just using the skills my teacher thought me.

Answer:

I believe you can just distribute (multiply) the coefficient (the number/value that is outside of the parentheses) by the rest of the values.

Step-by-step explanation:

So c. would be (20y * 1/5) (-4x * 1/5) (-13 * 1/5) then you just solve.
