What is the value of x

Mathematics
1 answer:
RideAnS [48]2 years ago
4 0

Answer:

x=5

Step-by-step explanation:

We can use the Triangle Angel Bisector Theorem


AB             2x-1

----------= --------------

AC               3x

9              2x-1

----------= --------------

15               3x


Using cross products

3x*9 = 15*(2x-1)

Distribute

27x = 30x-15

Subtract 30x from each side

27x-30x = 30x-30x-15

-3x = -15

Divide by -3

-3x/-3 =-15/-3

x =5

Two card are pulled from a normal deck of 52 cards, without replacement.
8090 [49]

Answer:

The probability that both cards that are drawn are hearts is 1/17.

Step-by-Step-Explanation:

First off, know that there are 13 heart cards in the deck of 52 cards. Therefore, the chance of pulling a single heart card is 13/52. Let's say we do pull a heart card. Since there is no replacement for the heart card taken out of the deck, we now have 12 heart cards out of a deck of 51 cards. The chance of pulling out a heart card in now 12/51. To find the probability that both cards drawn out are hearts, multiply the two fractions together: (13/52)⋅(12/51)=156/2652=1/17.

<h2></h2><h2>So hence, your answer is 1/17</h2>

Which of these ordered pairs is the best estimate of the solution of the system y = 3x + 2 and y = -1/4 x + 1?
Lelu [443]
If the solution exists, y=y....

3x+2=-x/4+1  make everything have a common denominator of 4...

(12x+8)/4=(-x+4)/4 now multiply both sides by 4

12x+8=4-x  add x to both sides

13x+8=4  subtract 8 from both sides

13x=-4  divide both sides by 13

x=-4/13

x≈-0.31  and the only pair in your choices having an x value close to that is:

(-0.3, 1.1)

Divide 56 in the ratio 5 3
bogdanovich [222]
I don't understand what you need.

But,

5 + 3 = 8

56/8 = 7

7*5 = 35
7*3 = 21

Hope this helps !
