Answer:
x = 5
Step-by-step explanation:
To solve this, we just have to the multiplication and do the simplification (adding up the similar terms) afterwards:
3(x+1)=7(x-2)-3 becomes...
3x + 3 = 7x - 14 - 3
3x + 3 = 7x -17
Then we move all x's on one side and all plain numbers on the other side, we'll move the x's to the right since there's a bigger value there, and will move the plain numbers on the left side, by subtracting 3x and by adding 17 on both sides
3x + 3 - 3x + 17 = 7x -17 + 17 - 3x
20 = 4x
If we isolate x alone we have:
20/4 = x or x = 5
Answer:
36 black socks
Step-by-step explanation:
white socks: black socks
1 :3
We have 12 white socks so we multiply each term by 12
1*12 : 3*12
12:36
We have 36 black socks
Answer:
Option c) Transitivity
Step-by-step explanation:
We are given the following information in the question:
If A exceeds B in some property and B exceeds C, then A must also exceed C.
We have to define the property shown by A,B and C.
Transitivity:
- It is a mathematical property which states that between three numbers if first and second share the property, second and third share the property, then according to transitive property, the property holds between first and third as well.
Thus, A, B and C here shows the transitive property.
The correct answer is
Option c) Transitivity
