Answer:
x = 5
Step-by-step explanation:
This equation can be rearranged in order to easily solve.
First, rearrange the equation by simply flipping it.
3x + 30 = 9x → 9x = 3x + 30
Then, you may solve for x.
9x = 3x + 30 subtract 3x from both sides of the equation
6x = 30 divide by 6 on both sides of the equation
x = 5
Answer:
The average rate of change for this sequence is 1
Step-by-step explanation:
The average rate of change is calculated as the slope of the line joining the end points of the sequence.
In this case the end points are;
(-.5, 2.5) and (1,4)
We simply calculate the slope using the gradient formula;
Change in y / change in x
(4 - 2.5)/(1 - -0.5) = 1
Answer:
For this problem, you could just multiply $5 by 2 OR you could divide $5 by nine to find your Unit Rate and then multiply that number by 18.
Using pythagoras length of the other leg = sqrt ( 8^2 - 4^2) = sqrt 48 = 4 sqrt3
the ratio of the sides of the triangle = 8 : 4 :4 sqrt3 = 2:1:sqrt3 so this is a
30-60-90 degree triangle
