3a + 3b-2c-2d
a= number of hearts
b= number of diamons
c= number of clubs
d= number of spades
if you draw 3hearts, 2 diamonds, and 1 spade, just replace a=3, b=2, c=0, d=1
3(3) + 3(2)-2(0)-2(1)
Multiply each term and add the results:
9+6-0-2 = 13
13 points
 
        
             
        
        
        
Answer:
y = 3x - 5
Step-by-step explanation:
We know that the equation 'y = 3x + ?' intersects the point (1, -2). This means that when x = 1, y = -2 in out equation above. To solve this just plug in the x and y values to get '?'.

Now that we know '?' is -5, we write it back into slope intercept form, so our final answer is y = 3x - 5
 
        
             
        
        
        
Answer:
The second one
Step-by-step explanation:
 
        
             
        
        
        
24/7 = 180/x....24 ft to 7 seconds = 180 ft to x seconds
cross multiply
(24)(x) = (180)(7)
24x = 1260
x = 1260/24
x = 52.5....so it will take 52.5 seconds
