0.7n+0.8n=2.1
1.5n=2.1
n=1.4
Therefore, the answer is B.
$15 - $8 = $7.
$7 / 2 = $3.50
spends $3.50 on each card.
Answer:
The missing y -coordinate is 0.
Step-by-step explanation:
Here we know the slope but must find the y-coefficient of one of the points.
y - 2
The slope is m = 1/2 = rise / run = ----------
3 - 7
y - 2
or 1/2 = ---------- which simplifies to -2 = y - 2, which yields y = 0.
-4
The missing y -coordinate is 0.
