Step-by-step explanation:
6 1/5 divided by 2/3 = 18 3/5
Answer: y=5x+7
Step-by-step explanation:
Since we are given the slope, all we have to do is plug in the given point and solve for the y-intercept.
-3=5(-2)+b [multiply]
-3=-10+b [add both sides by 10]
b=7
Now, we know the equation is y=5x+7.

Answer:
x <40
Step-by-step explanation:
The income from the pens is 2*x
He made less than 80
2x <80
Divide each side by 2
2x/2 < 80/2
x < 40
Sine (28) = opposite / hypotenuse =
0.46947 = opposite / 28
opposite = 0.46947 * 28
<span><span><span>opposite side = 13.14516

</span>
cosine (28) = adjacent / hypotenuse =
0.88295 = adjacent / 28
adjacent = 28 * .88295
<span><span><span>adjacent side = 24.7226
