Answer:

x=20/3 y=17/3

Step-by-step explanation:

1. x-y=1

2. 2x+y=19

The first equation can be rewritten as 2x-2y=2

We can then subtract the second equation from this:

2x-2y=2

2x+y=19

-3y=-17

y=17/3

Plug this into to solve for x:

x-17/3=1

x=17/3+1

x=20/3

A card is drawn randomly from a deck of 52 cards.
Stels [109]

The probability of drawing a red face card from a deck of cards is 3/26

Explanation:

In a deck of cards, there are 6 red-faced cards.

Probability = No. of favourable events / Total no. of events

So, the probability of drawing a red-faced card is 6 out of 52 cards.

Thus, the probability of drawing a red face card from a deck of cards is 6/52 = 3/26.

kiruha [24]
B is true,
since b is larger than a. we see this from the 2 last statements.
n is subtracted form both of them, so b is still larger, and b-n is larger than a-n
