X/4 = x/20 + 1
Multiply through by 20, to get
5x = x + 20
5x - x = 20
4x = 20
x = 20/4 = 5
x = 5
Answer:
A. 11/3
Step-by-step explanation:
11/3 is saying 11 dived by 3, and in the short story the 11-inch string is being cut (divide) into 3 parts.
Hope this helped!
$21.30. You just have to add the numbers together.
Answer:
Simplifying
4x + 9 = 12x + -3
Reorder the terms:
9 + 4x = 12x + -3
Reorder the terms:
9 + 4x = -3 + 12x
Solving
9 + 4x = -3 + 12x
Solving for variable 'x'.
Move all terms containing x to the left, all other terms to the right.
Add '-12x' to each side of the equation.
9 + 4x + -12x = -3 + 12x + -12x
Combine like terms: 4x + -12x = -8x
9 + -8x = -3 + 12x + -12x
Combine like terms: 12x + -12x = 0
9 + -8x = -3 + 0
9 + -8x = -3
Add '-9' to each side of the equation.
9 + -9 + -8x = -3 + -9
Combine like terms: 9 + -9 = 0
0 + -8x = -3 + -9
-8x = -3 + -9
Combine like terms: -3 + -9 = -12
-8x = -12
Divide each side by '-8'.
x = 1.5
Simplifying
x = 1.5
Step-by-step explanation:
As per the problem,
Marco wants to use the distributive property to find the value of 17 • 69 + 17 • 31.
We have been asked to find , which expression can be used?
As per the distributive property , we know that
Now apply this on the given expression we get
Hence the expression , which can be used is 17(69+31)
