if you divide 32 by 4 its 8
Answer:
(c) (x +7)/3
Step-by-step explanation:
Factor each expression and cancel common factors.
Answer:
5
Step-by-step explanation:
Simplifying
8 + 4 = 2(x + 1)
Combine like terms: 8 + 4 = 12
12 = 2(x + 1)
Reorder the terms:
12 = 2(1 + x)
12 = (1 * 2 + x * 2)
12 = (2 + 2x)
Solving
12 = 2 + 2x
Solving for variable 'x'.
Move all terms containing x to the left, and all other terms to the right.
Add '-2x' to each side of the equation.
12 + -2x = 2 + 2x + -2x
Combine like terms: 2x + -2x = 0
12 + -2x = 2 + 0
12 + -2x = 2
Add '-12' to each side of the equation.
12 + -12 + -2x = 2 + -12
Combine like terms: 12 + -12 = 0
0 + -2x = 2 + -12
-2x = 2 + -12
Combine like terms: 2 + -12 = -10
-2x = -10
Divide each side by '-2'.
x = 5
Simplifying
x = 5
Answer:
x=14
Step-by-step explanation:
1 way
Step 1: Subtract 3/4x from both sides.
1/4x − 5 − 3/4x=3/4x−12−3/4x
−1/2x−5=−12
Step 2: Add 5 to both sides.
−1/2x−5+5=−12+5
−1/2x=−7
Step 3: Multiply both sides by 2/(-1).
(2/−1)*(−1/2x)=(2/−1)*(−7)
2nd way
Add 5 to both sides
1/4x - 5+5 = 3/4x - 12+5
Simplify
1/4x = 3/4x -7
Subtract 3/4x from both sides
1/4x-3/4x= 3/4x-7-3/4x
Simplify
-1/2x=-7
Multiply both sides by -2
(-1/2x)(-2)=(-7)(-2)
x=14
sorry it to so long
the second picture is not acceptable
The sixth graders collected $250 of their $300 goal. The seventh graders collected $250 of thier $450 goal.
Sixth Graders:
$250 / $300
Reduce: $25 / $30 = 5/6
Seventh Graders:
$250 / $450
Reduce: $25 / $45 = 5/9
