He bought 36 baseball cards. Since 3/4 of the 48 cards are baseball cards, you need to find 75% of 48, which is 75*48, which is 36 cards. Hope this helps.

How many solutions does the equation 6a − 3a − 6 = −2 + 3 have?

Bogdan [553]

Answer:

One. It is a = 7/3

Step-by-step explanation:

Let's simplify the equation 6a − 3a − 6 = −2 + 3 by combining like terms:

3a - 6 = 1

Adding 6 to both sides, we get:

3a = 7.

Dividing both sides by 3, we get

a = 7/3.

This equation has ONE solution, which is a = 7/3.

Choose the equation that represents the line that passes through the point (6,-3,) and has a slope of 1/2

dezoksy [38]

Answer:

$y=\frac{1}{2}x-6$

Step-by-step explanation:

The general equation of a line: $y = ax+b$

In our case <em>a</em> is given

$a=\frac{1}{2}$

Now we plug in for <em>a</em> and we get:

$y=\frac{1}{2}*x+b$

Now we plug in our coordinates into this equation and we solve for <em>b</em>

$-3=\frac{1}{2}*6+b\\b = -6$

So the equation of the line is $y=\frac{1}{2}x-6$
