El cuadruple de un número aumentado en 2 es menor igual a 50

Mathematics
1 answer:
Alchen [17]3 years ago
8 0

Answer:

4\cdot x + 2 \leq 50. La solución de la inecuación es todo número real menor o  igual a 12.

Step-by-step explanation:

El primer paso consiste en traducir la expresión en una expresión algebraica:

1) Un número: x

2) El cuádruplo de un número: 4\cdot x

3) El cuádruplo de un número y aumentado en 2: 4\cdot x + 2

4) El cuádruplo de un número y aumentado en 2 es menor o igual que 50: 4\cdot x + 2 \leq 50

Como siguiente paso, se resuelve la inecuación por métodos algebraicos:

1) 4\cdot x + 2 \leq 50 Dado

2) 4\cdot x \leq 48 Compatibilidad con la adición/Existencia del inverso aditivo/Modulatividad en la adición.

3) x \leq 12 Compatibilidad con la multiplicación/Existencia del inverso multiplicativo/Modulatividad en la multiplicación/Resultado.

En consecuencia, la solución de la inecuación es todo número real menor o  igual a 12.

A recreation center charges nonmembers $3 to use the pool and $5 to use the basketball courts. A person pays $42 to use the recr
Andrei [34K]
Let x = times in the pool
Let y = times in the basketball courts

42=3x+5y
x+y=12
Therefore y = 12-x
Subsitute for y
42 = 3x + 5(12-x)
42 = 3x + 60 -5x
Subtract 60
-18 = -2x
9 = x

The person used the pool 9 times.

If sin θ = 3/5 find the value of 4 tanθ + 3 sinθ – 6 cosθ
zepelin [54]

Step-by-step explanation:

If sine theta is 3/5, taking the sine inverse will give you 36.87°.

4tan theta is 4 × tan36.87 = 3

3sin theta = 3 × sin36.87 = 1.8

6cos theta is 6× cos36.87 = 4.8

Therefore, it becomes 3 + 1.8 - 4.8 = 4.8 - 4.8

The answer is 0

Jim is M years old. His daughter is 21 years yonger than him. How old is Jim's daughter. Express your answer in terms of M.
Gre4nikov [31]

Answer: M - 21


Step-by-step explanation:

Since his daughter is 21 years younger than he is (M) all you have to do is take his age and subtract 21 (how many years older he is) to get her age.


At first this might seem difficult because you don't know what M is equal to but in the context of this question you don't need to know M.

If you're ever stuck just give an imaginary number to M such as 50.

If you take 50 and subtract 21 you get 29, this makes sense because his daughter is of course younger than him.

You can also use this tatic to solve problems like x+3=x/2 (or something like that) just to check and make sure that the two equations do equal each other.

6x − 3y = 7, −2x + y = −8 <br><br> x=?<br> y=?
kap26 [50]

Answer:

no solution

Step-by-step explanation:

6x - 3y = 7 → (1)

- 2x + y = - 8 → (2)

multiplying (2) by 3 and adding to (1) eliminates the variables

- 6x + 3y = - 24 → (3)

add (1) and (3) term by term

0 + 0 = - 17

0 = - 17 ← false statement

This indicates the system has no solution
