the average of two numbers is 34 the first number is three times the second number what are the two numbers
tino4ka555 [31]
Hi there!

To solve this problem, we need to set up two equations and use the system of equations to solve.

Let x be the first number.
Let y be the second number.

(x + y) ÷ 2 = 34
x = 3y

Now, we can use substitution to solve.

(3y + y) ÷ 2 = 34
4y ÷ 2 = 34
2y = 34
y = 17

Now, we plug the value of y in the equation to solve for x.

x = 3*17
x = 51

Hope this helps!

alisha [4.7K]

Let's call the aces h, d, c, s for hearts, diamonds, clubs and spades. So, h, d are red and [ted] c, s[/tex] are black.

Since the first card is replaced, the two picks are identical. This means that the sample space is given by all the possible couple

(x,y)\, x, y \in \{h,d,c,s\}

There are 16 such couples (we have four choices for the first card, and the same four choices for the second card). Now let's compute the odds in our favour to deduce the probability of winning:

If we want a player to draw two card of the same colour, the following couples are good:

(h,h),\ (h,d),\ (d,h),\ (d,d),\ (c,c),\ (c,s),\ (s,c),\ (s,s)

so 8 possible couples over 16. This means that the probability that a player draws two cards of the same color is 8/16 = 1/2.

Similarly, the probability of drawing a red ace first and then a black ace is represented by the following couples:

(h,c),\ (h,s),\ (d,c),\ (d,s)

which are 4 over the same 16 as above, thus leading to a probability of 4/16 = 1/4.

What is the solution to the equation X/2- 4 = 6? <br><br> x = 1 <br> x = 5 <br> x = 10 <br> x = 20
jeka94

[ Answer ]

\boxed{\bold{X \ = \ 20}}

[ Explanation ]

  • Solve: X ÷ 2 - 4 = 6

--------------------------

  • Rewrite Equation

\frac{X}{2} - 4 = 6

  • Add 4 To Both Sides

\frac{X}{2} - 4 + 4 = 6 + 4

  • Simplify

\frac{X}{2} = 10

  • Multiply Both Sides By 2

\frac{2x}{2} = 10 · 2

  • Simplify

X = 20

\boxed{\bold{[] \ Eclipsed \ []}}
