Solve the following system of equations. y = 12 - 5x 2x + 3y = 11

1 answer:

4 0

Use substitution
2x + 3(12 - 5x) = 11
Distributive property
2x + 36 - 15x = 11
Combine like terms
-13x + 36 = 11
Subtract 36
-13x = -25
x = 25/13
y = 12 - 5(25/13)
y = 31/13
Solution: x = 25/13, y = 31/13

Answer:

x=3, y=-1. (3, -1).

Step-by-step explanation:

x-3y=6

2x+2y=4

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

x=3y+6

2(3y+6)+2y=4

6y+12+2y=4

8y+12=4

8y=4-12

8y=-8

y=-8/8

y=-1

x-3(-1)=6

x+3=6

x=6-3

x=3

The odds against Carl beating his friend in a round of golf are 7:5. Find the probability that carl will beat his friend.

Leya [2.2K]

Answer:

$\frac{5}{12}$

In other words, carl's losing odds are 7 : 5, so his winning odds will be 5 : 7

So if they play (7+5=12) 12 times, carl will win 5 times.

To find probability that carl will beat his friend, we take the probability of Carl winning. Simple!

The probability is 5/ 12
