Answer:
The value of x is 2/3.
Step-by-step explanation:
The perimeter of a square is 4s.
Substitute the value and simplify.
4( 3x - 2 ) Distribute
12x - 8 In this case this is an equation
12x - 8 = 0 Add 8 on both sides
12x = 8 Isolate the variable by dividing 12 on both sides
x= 2/3
You must isolate the variable in order to solve equations with variables.
Isolating variable is basically when you divide, multiply, add, or subtract to put a variable on <em><u>ONLY </u></em>one side of the equation.

Answer:
Pretty sure it's 29
Step-by-step explanation:
The triangle has to be 180 degrees so 15+36=51 180-51=29
Answer:
Step-by-step explanation:
Check the attached diagram... since they are parallel lines, those angles should be equal. now as per the theorem of opposite angles, (3x + 10)° should be equal to 70° .
(3x + 10)° = 70°
3x = 60°
x = 20
6x - 5 > -29
Solve for x and thus it will be:
6x > -24
X > -4.
All values greater than -4 will make the following inequality true.
Answer:
x = -1 , y = 6
or (-1, 6)
Step-by-step explanation:
First solve for "y" in the second equation:
and now, use this result as a substitution for "y" in terms of "x" in the first equation:
Knowing the value of "x", now we place it in the substitution equation to find "y":
