What is 2x=y-10 x+7=y

Mathematics
1 answer:
Triss [41]3 years ago
8 0

Answer:

x = -3

y = 4

Step-by-step explanation:

first i plug y=x+7 for y on 2x=y-10

this makes it 2x=x+7-10

then i solve 7-10 to get 2x=x-3

i subtract -x from both sides to get x=-3

so i plug in x=-3 to x+7=y to get -3+7=y which makes y=4

Use the theoretical probability formula to solve the problem. Express the probability as a fraction
serg [7]

Answer:

c. 3 / 13

d. 2 / 13

Step-by-step explanation:

c.

A deck of cards has 52 cards. There are cards of 4 suits- Spades, Hearts, Diamonds and Clubs.

So, there are 52/4= 13 cards of each suit.

Among these 13 cards, there are 3 picture cards or face cards as they are called. These are the Jack, Queen and King cards.

So, the number of total picture cards = 4*3 = 12

the number of cards are 52

theoretical probability formula: P =  favorable events/  possible events

P = 12 / 52

P = 3 / 13

d.

there are four aces and four sevens in the deck

so favorable events = 4 + 4 = 8

possible eventas = 52

P = 8 / 52

P = 2 / 13
