<span>Let's call these friends by their first initial:
K = Kiana, G = Gary, M = Monty, W = Willa
Now we can convert the question to a system of linear equations:
Gary has 3 cards more than Kiana, so G = K + 3
Monty has 7 cards more than Kiana, so M = K + 7
Willa has twice as many cards as Monty, so W = 2M = 2(K + 7) = 2K + 14
74 cards given out = all the friends combined, so
74
= K + G + M + W
= K + (K + 3) + (K + 7) + (2K + 14)
= 5K + 3 + 7 + 14
= 5K + 24
50 = 5K
10 = K, so Kiana had 10 cards
G = K + 3 = 13, so Gary had 13 cards
M = K + 7 = 17, so Monty had 17 cards
W = 2M = 34, so Willa had 34 cards
Checking our work, 10 + 13 + 17 + 34 = 74 cards total.</span>
Answer:
3 for 5.19
Step-by-step explanation:
Answer:
-5/2
Step-by-step explanation:
to find the slope of the line, you have to do y1 - y2, over x1 - x2. That means that you do -5/2, and so that is the answer
Answer:
Step-by-step explanation:
So the slope of the line is y = -9x + b
We have
y = -9x + b
Add 9x to both sides
y + 9x = -9x + 9x + b
y + 9x = b
switching sides,
b = y + 9x
Plug in the (x, y) values for point (4, 0)
b = 0 + 9(4)
b = 36
So the equation of the line is
Answer:
y= -2x+5
