Answer:

<h2>x = -4</h2>

Step-by-step explanation:

3x+5=x-3\qquad\text{subtract 5 from both sides}\\\\3x+5-5=x-3-5\\\\3x=x-8\qquad\text{subtract}\ x\ \text{from both sides}\\\\3x-x=x-x-8\\\\2x=-8\qquad\text{divide both sides by 2}\\\\\dfrac{2x}{2}=\dfrac{-8}{2}\\\\x=-4

Adriana, Henry, Malik, and Richard each design surveys to determine the most popular way seventh graders purchase music. Adriana
andriy [413]
The sample which is likely to produce the most valid result is Richard's sample because there was no statistical bias. Statistical bias is the systematic favoritism of certain individuals in the study. Just like what Adriana, Henry and Malik did in conducting their surveys, they choose people who are point of interest and also who are near them. In the way Richard conducted his survey, he used a random sampling technique, this is a method of selecting a sample from a population in such a way that every possible individual can be chosen and he doesn't know who these people are.

Question 6 of 10 The triangles shown below may not be congruent. 1) 25° 55° 100° 100° 66° 25° O A. True O B. False​
Blizzard [7]

Answer:

True, they may not be congruent

Step-by-step explanation:

A figure cannot be determined as congruent from three angles alone. In order  for two shapes to be congruent, all corresponding parts must be congruent. This means all the sides and angles of the two shapes must be the same in order for the two shapes to be congruent. If we know all the angles are the same, the sides could still be different lengths, so this does not prove congruency.
