80=-8a
We are trying to solve for a. So we need to get a alone. To do that we have to divide each side by -8.
80/-8= -8a/-8
Once you have solved each side you will get the following.
-10=a
In the problem of insufficient data quantities. I can get a general solution.We know that tangent to a circle is perpendicular to the radius at the point of tangency. It's mean that triangles LJM and LJK are rights.
Let angle JLK like X.
So, angle JLM=61-x.
And it's mean that by using right triangle trigonometry
Radius MJ = LM*cos(61-X)
Answer: 8 seconds
Step-by-step explanation:
d = rt
the distance is 20
the rate is 2.5
20 = 2.5t
t = 20/2.5
t = 8
Answer:
x = - 6.8
Step-by-step explanation:
Solve for 3/4(x) − 1.72 = −6.82
3/4 (x) = -6.82 + 1.72
3/4 (x) = -5.10
x = 4 * -5.1 / 3
x = 4 * - 1.7
x = - 6.8
