Answer:
1/3 =5x-2
3(1/3)=3(5x-2)
1=15x-6
7=15x
x=7/15 (7/15 , 1/3)
Step-by-step explanation:
Answer:
m∠BAC = 105°
m∠FAB = 75°
Step-by-step explanation:
By using the property of an exterior angle of a triangle,
Measure of an exterior angle is equal to the sum of opposite two angles of a triangle.
From the triangle given in the picture,
m∠ABC + m∠BCA + m∠CAB = 180°
(13x - 3)° = (3x + 2)° + 55°
13x - 3 = 3x + 57
13x - 3x = 57 + 3
10x = 60
x = 6
m∠FAB = (13x - 3)° = 75°
m∠ABC = (3x + 2)° = 20°
Since, ∠BAC and ∠FAB are the linear pair of angles,
m∠BAC + m∠FAB = 180°
m∠BAC + 75° = 180°
m∠BAC = 180° - 75° = 105°
I might want to use the commutative property to change the order of the integers in the following sum before adding the given expression
"-80 + (-173)+(-20)"
As commutative property states that " Changing the order of addends does not change the sum" which means if we add 'a' to 'b' or 'b' to 'a', we will get the same answer.
Therefore, here if we add '-80' to '-173' or '-173' to '-80' , or if we add '-173' to '-20' or '-20' to '-173' , we will get the same answer.
Therefore, we might use commutative property to change the order the of integers in the following sum.
<span>2x-1=4(x+1)
Given.
This is the expression you were originally given.
2x-1=4x+4
Distributive Property
You distributed the 4 in the subexpression 4(x + 1) to make 4x + 4
2x=4x+5
Addition or Subtraction Property of Equality
You added 1 to both sides of the equation.
â’2x=5
Addition or Subtraction Property of Equality
You subtracted 4x from both sides of the equation.
x=-5/2
Multiplication or Division Property of Equality
You divided both sides by -2.</span>
