There are 5 yellow cards, 3 blue cards, and 7 red cards in a bag. A card is chosen at
Alik [6]

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

Help Picture below ..........
Nataly_w [17]

Answer:

A

Step-by-step explanation:

Multiply them according to the problem.

6x+2y=6 \\ \\ -3(6x+2y)=(6)*-3 \\ \\ -18x-6y=-18 \\ \\ \\ 7x+3y=9 \\ \\ 2(7x+3y)=(9)*2 \\ \\ 14x+6y=18

As you can see, the only terms in the two equations that can cancel out are -6y and 6y.

Solve each equation for x<br> 4(x + 4) + 2x= 52
Alex73 [517]

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
