Answer:

5x - 4 = 56

2x + 3 = 27

Step-by-step explanation:

2(5x - 4 + 2x + 3) = 166

10x - 8 + 4x + 6 = 166

14x - 2 = 166

+ 2 +2

14x = 168

divide both sides of the equal sign by 14

5(12) - 4 = 60 - 4 = 56

2(12) + 3 = 24 + 3 = 27

In a lottery, the top cash prize was $642 million, going to three lucky winners. Players pick five different numbers from 1 t

kramer

Answer:

$\frac{10}{53 \times 46 \times 26}$

Step-by-step explanation:

The probability of matching the number drawn on the gold ball is

$\frac{1}{46}$

The number of possible pairs of numbers from 1 to 53 is

$\binom{53}{2} = \frac{53 \times 52}{2} = 53 \times 26$

Choosing 5 numbers, you are choosing 10 different pairs:

$\binom{5}{2} = \frac{5 \times 4}{2} = 10$

Therefore the probability of correctly matching the drawn pair is

$\frac{10}{53 \times 26}$

Thus, the probability of winning (matching the pair AND the gold ball) is

$\frac{10}{53 \times 46 \times 26}$

Two numbers have a average of 17. If one of the numbers is 11, what is the other number

Len [333]

Answer:

Other number is 23

Step-by-step explanation:

Let the two numbers be x and y.

We have given that average of x and y is 17.

i.e $\frac{x+y}{2} = 17$

if one of the number is 11,

Then , $\frac{11+y}{2} = 17$

or (11 + y)/2 = 17

or 11 + y = 34

or y = 34 - 11

or y = 23
