enyata [817]

Answer:

Cara:108

Step-by-step explanation:

John: x number of cards

Cara: 12 times x number of cards(she has 12 times more cards than John)

Cara+John=117 cards

12 \times x + x = 117 \\ 13x = 117 \\ x =  \frac{117}{13}  \\ x = 9

Cara has 12×9 cards, so she has 108 cards.

Hope this was helpful :)

PtichkaEL [24]

Answer:

18 inches.

Step-by-step explanation:

If the ratio for inches to miles is

Solve for b2 in A=1/2 h(b1+b2), if A=16, h=4, and b1=3
icang [17]

Answer:

b_{2} = 5

Step-by-step explanation:

Substitute the given values into the formula

16 = \frac{1}{2} × 4(3 + b_{2})

16 = 2(3 + b_{2}) ( divide both sides by 2 )

8 = 3 + b_{2} ( subtract 3 from both sides )

5 = b_{2}

8 thank you so much!!!

Answer:

C)  (-4, 2)

Step-by-step explanation:

It is easier to begin by putting the y equation back into the x equation so it would be rewritten as:

x= 2 (-2x - 6) - 8

Since you replace the y for the given y value

Distribute and you get

x = -4x -12 -8

Add 4x to both sides to get rid of it on the right and balance the equation

5x = -12-8 which is -20

5x = -20

divide by 5 gives you the value -4 for the x

Now simply put that value in for the y equation

y= (-2 (-4)) -6

y = 8 - 6

y = 2
