Answer:

\Huge \boxed{5x - 19}

\rule[225]{225}{2}

Step-by-step explanation:

A ——— B ——— C

AC = 8x - 20

AB = 3x - 1

BC = AC - AB

BC = (8x - 20) - (3x - 1)

Distributing negative sign.

BC = 8x - 20 - 3x + 1

Combining like terms.

BC = 5x - 19

\rule[225]{225}{2}

If 1" = 2.5' then how many feet is 3.75"=
Gnesinka [82]
1" = 2.5'
2.5'(3.75") = 9.375'

3.75" = 9.375'

For every inch is 2.5ft
1 - 2.5 ft
2 - 5 ft
3 - 7.5 ft 
.75' - 0.625 ft
7.5' + 0.625' = 9.375"

Find the probability of drawing a heart from the standard deck of cards and then drawing a 5 from any suit after the first card
Vinil7 [7]

The probability of drawing a heart from the standard deck of cards and then drawing a 5 is 1/52

<h3>How to determine the probability?</h3>

In a standard deck of cards, we have:

Total = 52

Heart = 13

5's = 4

Since the cards are replaced, the probability is calculated as:

P(Heart and 5) = Heart/Total * 5s/Total

This gives

P(Heart and 5) = 13/52* 4/52

Evaluate

P(Heart and 5) = 1/52

Hence, the probability of drawing a heart from the standard deck of cards and then drawing a 5 is 1/52
