Jordan was trading baseball cards with some friends. He gave 15 cards to Tommy and got 3 back. He gave two thirds of his remaini

Advocard [28]

87; If he gave two thirds of his remaining cards to Elaine, then he had one third left. If one third of his remaining cards is 25, then 25 x 3 will give you what he had after trading with Tommy. When he finished trading with Tommy he had 75 cards. if he gave away 15 cards, but got three back, then he must have had 87 cards to begin with.

Check your answer:

87-15 = 72

72+3 = 75

2/3 of 75 = 50

75-50 = 25

Great!

Y=3/4 x-4

pochemuha

Answer:

see graph of y=3/4 x-4

Step-by-step explanation:

Assuming you mean

$y = \frac34x - 4$

Below is a graph of that one. The slope is 3/4 and the interception with the y axis is at y=-4. The equation is in its normal form y=ax+b with a=3/4 (slope) and b=-4 (y intercept), so no conversion needed.

You have to be careful on how you write these equations down. It might very well be that you meant:

$y = \frac{3}{4x-4}$ or $y = \frac{3}{4x} - 4$

However, those are more complex so I'm hoping for the first one... ;-)

To draw a line segment perpendicular to XY passing through point x

Andrew [12]

What does perpendicular mean? Well, in elementary geometry it mean 2 lines that intersect at a right angle. (90°).

So for Part one. all you need to do is draw a straight line down from the point X. Name the end point of that line M.

Now you will connect the line M and Z.

Thats it! I hope this helped!! :)
