Subtraction property of equality is used when u have 2 sides with an equal sign in the middle and u want to subtract from both sides.
Example :
2x + 3 = 7 ....subtract 3 from both sides
2x + 3 - 3 = 7 - 3
2x = 4
x = 4/2
x = 2
When subtracting real numbers..if the numbers are on the same side of the equal sign...u can just subtract on that one side
Example :
2x = 7 - 3
2x = 4
x = 4/2
x = 2
14/3 or 4(2/3) is the answer
Answer:
1.31, 0.19 to nearest hundredth.
Step-by-step explanation:
1/x + 1/(x - 1) = 4
Multiply through by x(x - 1):-
x - 1 + x = 4x(x - 1)
4x^2 - 4x = 2x - 1
4x^2 - 6x = -1
4(x^2 - 3.2 x) = -1
Completing the square:-
4 [ ( x - 3/4)^2 - 9/16] = -1
4(x - 3/4)^2 - 9/4 = -1
4(x - 3/4)^2 = 5/4
(x - 3/4)^2 = 5/16
x - 3/4 = +/- √5 / 4
x = √5 / 4 + 3/4 , -√5 / 4 + 3/4
= 1.31, 0.19 to nearest hundredth.

Step-by-step explanation:
(x,y)... always x-axis first and then y-axis
Answer:
6/10
Step-by-step explanation:
Simplify 15/25 by dividing by 5/5
15/25 ÷ 5/5 = 3/5
Multiply 3/5 by 2/2 to convert to tenths
3/5 × 2/2 = 6/10
