2x + y = 16

Answers

Answer 1

Answer:

x = 6

y = 4

Step-by-step explanation:

16 - y + 3y = 24

y = 4

2x = 16 - 4

x = 6

(x, y) = (6,4)

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

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.

have only 10 roses left?

Answers

Answer:

1 vase arrangement when 10 roses are left

Step-by-step explanation:

1. so 50 divided by 5 is 10.

That means every arrangement is 10 roses.

2. it asks us to find how many vase arrangement will be needed to have only 10 roses left. We already know that we only need 1 arrangement, because we already found that out in step 1.

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°
