Answer:

Explicación paso a paso:

Primero, puede crear ecuaciones como este:

Carmen = x + 4x + 2

Daniel = 4x

Tomas = 9x + 2

Marco = 2

42 = 9x + 2 + x + 4x + 2 + 4x + x

38 = 19x

x = 2

La edad de Marco = 2, entonces:

Daniel = 4 (2) = 8

La edad de Daniel = 8

T = 9 (2) +2

Carmen = 5 (2) +2

La edad de Carmen = 12

entonces La edad de Tomás es = 20

Answer:

La edad de Tomas= 20.

Step-by-step explanation:

Primero, puede crear ecuaciónes como este:

C= x+4x+2

D=4x

T= 9x+2

M=2

42= 9x+2+x+4x+2+4x+x

38= 19x

x= 2

La edad de Marco= 2, entonces:

D= 4(2)= 8

La edad de Daniel=8

T= 9(2)+2

La edad de Tomas= 20

C= 5(2)+2

La edad de Carmen= 12

The main cables of a suspension bridge are ideally parabolic. the cables over a bridge that is 400 feet logn are attached to tow
Novay_Z [31]
Consider the diagram of the problem.

Let the vertex be on the y axis, exactly, at the point (0, 40)

Another point of this parabola is (200, 100), as can be checked from the figure.

The vertex form of the equation of a parabola is :

y=a(x-h)^{2}+k, where (h, k) is the vertex of the parabola, 

replacing (h, k) with (0, 40), we have:

y=ax^{2}+40

to find a, we substitute (x, y) with (200, 100):

100=a200^{2}+40

40,000a=60

a=60/40,000=3/(2,000)

So, the equation of the parabola is y= \frac{3}{2000} x^{2}+40

A mother is three times as old as her daughter, and the sum of their ages
garri49 [273]

Answer:

33

Step-by-step explanation:

If m = Mother's age and d = daughter's age, we can make the following equations

m = 3d

m + d = 44

Now, using substitution, we can substitute m for 3d in the second equation:

3d + d = 44, 4d = 44, d = 11

Then, we can plug d into the first equation: m = 3(11) = 33
