Answer:
Option C is correct
Step-by-step explanation:
5c – 20 ≤ 15c + 10
<=> 5c - 15c ≤ 20 + 10
<=>-10c ≤ 30
<=> c ≥ -3
Hope this helps!
Not sure if your trying to solve for x or v
Answer:
C.) each treatment is thought of as a value of the explanatory variable
Step-by-step explanation:
The main purpose for using randomization in an experiment is to control the lurking variable and establish a cause and effect relationship.
If we do not control lurking, or confounding, variables, we cannot accurately establish a cause and effect relationship; this means we cannot ensure that each treatment is a value of the explanatory variable.
Answer:
x = 27
Step-by-step explanation:
Both angles together form 180 degree.
Set your formula up as
180 = (5x+2) + (x + 16)
180 = 5x + 2 + x + 16
180 = 6x + 18
180 - 18 = 6x
162 = 6x
162/6 = x
27 = x
The measure of angle 1 and 2 should add up to 180°, because it forms a straight line. The same goes for the sum of angle 3 and 4.
Since we are given the measure of angle 2, we can find the measure of angle 1 by subtracting 143° from 180°.
180°-143° = 37°
We know that the intersecting lines form 2 sets of vertical angles, which are congruent. This means that the angles opposite from each other have the same measure. Therefore, both angle 2 & 4 have a measure of 143°, while angle 1 & 3 have a measure of 37°.
