3x = 6 (Subtraction)
x = 2
Give a reason for the last step in the argument shown.
A)
addition
B)
division
C)
subtraction
D)
multiplication
Answer: The correct answer is B) division.
Step-by-step explanation:
Hi, to answer this question we have to analyze the information given:
3(x + 4) = 18 (Given)
3x + 12 = 18 (Distributive Property)
3x = 6 (Subtraction)
x = 2
To obtain the result, in the last step we have to divide both sides by 3.
Mathematically speaking:
3x÷3 = 6÷3
x =2
So, the correct answer is B) division.
Feel free to ask for more if it´s necessary or if you did not understand something.
Answer:
x=1
Step-by-step explanation:
youll have to subtract 3 from 4
(-2,4) and (-2,8)
Answer:
4 units
Step-by-step explanation:
Given points:
As the x-coordinates of both points are the same, the two points line on the vertical line x = -2.
Therefore, to find the distance between the points, find the absolute value of the difference between their y-coordinates:
Therefore, the distance between points (-2, 4) and (-2, 8) is 4 units.
Answer:
+4
Step-by-step explanation: 4y and 8y would be 4 away from each other in the positive direction starting from 4y to get to 8y, therefore the diatance between (-2,4) and (-2,8) is 4
Answer:
82.4
Step-by-step explanation:
divide 51/13, multiply that result by 21.
