Cost per gallon is found by dividing the cost by the number of gallons.

$43.95/16.1 ≈ $2.7298137

Rounded to hundredths, this is $2.73.

X-4y=-22 solve for y
Arturiano [62]
Add 4y to both sides of the equation:
x=4y-22
Now replace x in the equation:
(4y-22)-4y=-22
Distribute the negative sign:
-4y+22-4y=-22
Add common terms:
-8y+22=-22
Add 8y to both sides of the equation:
8y-22=22
Add 22 to both sides of the equation:
8y=44
Divide both sides by 8:
y=5.5

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

Pls help with number 5
nikdorinn [45]
A is 3 (5) + 4 (0)>24 this is false because 3 times 5 equals 15 plus 4 time 0 which is 0 is 15 and 15 is less than 24 not greater than 24
A. IS FALSE
b is 3 (4) + 4 (3)>24 this is false because 3 times 4 equals 12 and 4 times three equals 12
12 plus 12 equals 24 and 24 is equaled to 24 not greater than
B IS FALSE
c is 3 (-2)+4(9)>24
3 times -2 is -6 plus 4 times 9 which is 36 is 30 30 is greater than 24 so
C IS TRUE
