If 3x − (7 − x) = 29, find the value of 6x.

Stells [14]

Answer:

Step-by-step explanation:

3x -(7-x) = 29 remove the parens

3x - 7 + x = 29 simplify

4x -7 = 29 add 7 to both sides of the equation

4x = 36 divide by

x = 9

then 6x = 6 * 9 = 54

How many pieces 3 and three fifths in. long can be cut from 28 metal rods each 15 in. long? Disregard waste.

Murrr4er [49]

Answer: 112 pieces

Step-by-step explanation:

1. Rewrite $3^{\frac{3}{5}}$ as a decimal. Divide the numerator and the denominator of the fractional part and add it to the integer part:

$3+0.6=3.6in$

2. You know that each metal rod is 15 inches long. Then, you must divide the lenght of each one by 3.6:

$pieces=\frac{15in}{3.6in}4.16$

3. The waste is 0.16, therefore, you obtain 4 pieces from a metal rod. The total pieces obtained from 28 metal rods are:

$total=4pieces*28=112pieces$

Is it proportional or nonproportional

azamat

4 is the proportion because 8 + 4 is 12 then keep adding 12 + 4 = 16 + 4 = 20 So that mean it is proportional I hope that helps.
