What is the difference in length between 1 1/4 inch button and a 3/8 inch button

jeka94

You have two buttons of different lengths.

First with length $1\dfrac{1}{4}$ in and second with length $\dfrac{3}{8}$ in. The first one is larger, then the difference in length between them is:

$1\dfrac{1}{2}-\dfrac{3}{8}=\dfrac{3}{2}-\dfrac{3}{8}=\dfrac{3\cdot 4-3}{8}=\dfrac{12-3}{8}=\dfrac{9}{8}=1\dfrac{1}{8}\ in.$

Answer: $1\dfrac{1}{8}$ in.

Simplify 3(2x+4y-2z)+7(x+y-4z)

Nostrana [21]

$3(2x + 4y - 2z) + 7(x + y - 4z)$
Remove parenthesis.
Distribute 3 and 7 through the parenthesis

$= 6x + 12y - 6z + 7x + 7y - 28z$
Collect the like terms by adding their coefficients.

$= 13x + 12y - 6z + 7y - 28z$
Collect the like terms by adding their coefficients.

$= 13x + 19y - 6z - 28z$
Collect like terms by calculating the sum or difference of their coefficients. Use addition and subtraction rules to calculate the expression.

$= 13x + 19y - 34z$
