Answer:
Isolate the variable by dividing each side by factors that don't contain the variable.
4(x−7)=2(x+3)
Simplify both sides of the equation.
4(x−7)=2(x+3)
4x+−28=2x+6
4x−28=2x+6
Subtract 2x from both sides.
4x−28−2x=2x+6−2x
x−28=6
Add 28 to both sides.
2x−28+28=6+28
2x=34
Divide both sides by 2.
2x/2 = 34/2
x = 17
C. they are worth the same amount of money, 1/2 and 2/4 are both 50% or 50 cents
Answer:
The sum of the measures of the interior angles of an octagon =(8−2)180° . The sum of the measures of the interior angles of an octagon is 1080° .
Answer:
x = 3
Step-by-step explanation:
x + 4 = 7 ( isolate x by subtracting 4 from both sides )
x = 3
Answer:
( 1, -6 )
Step-by-step explanation:
The solution to the graph is ( 1, -6 ) as that is the point where both equations cross. To double check you can also fill in the equations with the points given and they both should solve.
