Answer:
Question 21: C.
Question 22: I.
Question 23: E.
Question 24: B.
Step-by-step explanation:
#21: The first statement is presented in the "Given" section.
#22: Since the reflexive property states that anything is equal to itself, BC ≅ BC.
#23: C being the midpoint of AD means that C is the same distance from both point A and point D. This then means that AC ≅ CD.
#24: AB ≅ DB due to the given, BC ≅ BC (since it's the same side), and we've proven that AC ≅ CD using a midpoint. We've proven <em>all three sides</em> on the two triangles to each other are congruent. This means that we've proven the triangles using SSS, which is B.

Step-by-step explanation:
Answer:
42%
Step-by-step explanation:
x is for the volume of the container
the amount filled in the first container=0.30x
the volume of the first container + 50% of the second=(x+x*50%)=1.5 x
the amount of acid in the second container= 1.5x * 50%=0.75x
total amount of acid in the third one =0.3x+0.75x=1.05x
total solution : x+1.5x=2.5x
percentage=1.05x/2.5x= 0.42 or 42%
Answer: 8 is the coefficient of x .
Step-by-step explanation:
Since, a numerical or constant quantity placed before and multiplying the variable in an algebraic expression is called coefficient of that variable.
Here the given expression,
5x + 6 - 4y - 3 + 3x - 2
= 5x + 3x - 4y +6 - 2
= (5+3)x -4y + 4
= 8x - 4y + 4
Where 8 is the constant that placed before x that is 8 is the coefficient of x.
