Answer:
0.714
Step-by-step explanation:
Argument
The total number of cards = 5 yellow. 3 blue and 7 red = 15 cards in all.
The probability of choosing a yellow card first is 5/15 = 1/3.
We are now down to 14 cards
There are 3 blue cards.
P(yellow then blue) = 1/3 * 3/14
P(yellow then blue) = 1/14 = 0.0714
Answer:
The slope is 5
Step-by-step explanation:
This equation is in slope intercept form
y = mx +b
where m is the slope and b is the y intercept
y = 5x+4
where 5 is the slope and 4 is the y intercept
Answer:
A
Step-by-step explanation:
Multiply them according to the problem.
As you can see, the only terms in the two equations that can cancel out are 
and 
.
Answer:
x=6
Step-by-step explanation:
4(x + 4) + 2x= 52
We solve the bracket first by multiplying x+4 by 4
4x+16+2x=52
Collect like terms
4x+2x+16=52
6x+16=52
6x=52-16
6x=36
Divide both sides by 6
6x/6=36/6
x=36/6
x=6
To check for accuracy. We subsitute x for 6 in the equation and both sides of the equation must be equal
4(x + 4) + 2x= 52
4(6+4)+2(6)=62
4(10)+2(6)=52
40+12=52
52=52
