Answer:
Each multiple will always be divisible by 3
Step-by-step explanation:
I think you get 35% by first adding up everyone that was surveyed so
<span>190+135+220= 545 </span>
<span>Next you would divide 190 by the total number of people surveyed so </span>
<span>190/545= 0.348... </span>
<span>Since there is an 8 next to the 4 you would round up therefore getting 35% </span>
<span>I think that is how they got 35%</span>
Answer:
3n + 3
Step-by-step explanation:
Mia is correct
When n= 1 , 3n + 3 = 3*1 + 3 = 3 + 3 = 6
When n =2, 3n + 3 = 3*2 + 3 = 6 + 3 = 9
When n = 3 , 3n +3 = 3*3 + 3 = 9 + 3 = 12
When n = 4, 3n + 3 = 3*4 + 3 = 12 +3 = 15
First, solve 10x + y = -20 for y: y = -20 - 10x
Next, substitute -20 -10x for y in the second equation:
-20 - 10x = 2x^2 - 4x - 16.
Rearranging, 2x^2 + 6x + 4 = 0
Simplifying, x^2 + 3x + 2 = 0
The roots of this poly eqn are -1 and -2. Therefore, x = -1 and x = -2.
One by one, subst. these x-values into y = -20 - 10x to find the corresponding y-values.
Your answers should look like this: (-1, y) and (-2, y) (different values for y).
