Tell whether the angles are adjacent or vertical. Then find the value of x.

Answers

Answer:

  x = 63°

Step-by-step explanation:

~ They are adjacent angles because they have a common (one) vertex.

~ To find the value of x we must make an equation.

Angles on a straight line add up to 180°.

  117 + x = 180

  x = 180 - 117

  x = 63°

Answer:

63

The graph shows two lines, A and B.

A graph is shown with x- and y-axes labeled from 0 to 6 at increments of 1. A straight line labeled A joins the ordered pair 2, 6 with the ordered pair 6, 2. Another straight line labeled B joins the ordered pair 0, 3 with the ordered pair 4.5, 6.


Part A: How many solutions does the pair of equations for lines A and B have? Explain your answer.


Part B: What is the solution to the equations of lines A and B? Explain your answer

Answers

Answer:

C(2, 2) is the solution to both lines A and B.

Step-by-step explanation:

Line A is given as:

A straight line labeled A joins the ordered pair 3, 0 and the ordered pair 0, 6.

We know that the equation of a line passing through (a,b) and (c,d) is calculated as:

Hence, the equation of line is:

Hence, equation of line A is:

Similarly B is a line passing through (0,0) and (5,5).

Hence, the equation of line B is:

So, from the graph we observe that, the point of intersection of the two lines is (2,2).

Thus, option C is correct.

The ratio of chairs to tables in the conference room is 6 to 1. For every able, there are
there are 3 tables, there will be
chairs

Answers

ANSWER: 18

SOLUTION: if the ratio of chairs to tables is 6 to 1 and there are 3 tables in the room you just times 3 by six to get the amount of chairs.

The ratio of chairs to tables in the conference room is 6 to 1. For every table, there are 3 tables, then, the amount of chairs is 18.

What is the unitary method?

The unitary method is a method for solving a problem by the first value of a single unit and then finding the value by multiplying the single value.

The ratio of chairs to tables in the conference room is 6 to 1.

For every table, there are 3 tables,

if the ratio of chairs to tables is 6 : 1 and there are 3 tables in the room  

Then, the amount of chairs = 6 x 3

                                             = 18

Calcula 2 números tales que la suma del primero más el triple del segundo sea 85 y la diferencia entre el cuadruple del primero y el doble del segundo sea 102...

Answers

Calcula dos números tales que la suma del primero mas el triple del segundo sea 85 y que la diferencia entre el cuádruple del primero y el doble del segundo sea 102

Sea el primer número = T
Sea el segundo número = U

Las ecuaciones según el enunciado son:
1) T + 3U = 85
2) 4T - 2U = 102

Resolvemos por el MÉTODO DE IGUALACIÓN.
-Despejamos T en las dos ecuaciones.
T + 3U = 85 4T - 2U = 102
T = 85 - 3U 4T = 102 + 2U
T = (85 - 3U)/1 T = (102 + 2U)/4

Igualamos las dos ecuaciones entre sí.
(85 - 3U)/1 = (102 + 2U)/4

Multiplicamos las ecuaciones en cruz.
4 (85 - 3u) = 1 (102 + 2U)
340 - 12U = 102 + 2U
- 12U - 2U = 102 - 340
- 14U = - 238
U = - 238/-14
U = 17

El valor de U lo reemplazamos en uno de los despeje de T para hallar el valor de la misma.
T = (85 - 3U)/1
T = (85 - 3 (17)/1
T = (85 - 51)/1
T = 34/1
T = 34

Rpt. Los números son: 34 y 17



COMPROBAMOS LA SOLUCIÓN.
T + 3U = 85
34 + 3 (17) = 85
34 + 51 = 85
85 = 85



4T - 2U = 102
4 (34) - 2 (17) = 102
136 - 34 = 102
102 = 102
