For what question do you need help with?
Answer:The value of w cannot be a negative number, substitution is used to replace the variable L with a value of 20, the subtraction property of equality is used to isolate the term with the variable w.
Step-by-step explanation:
1: x + 8.23 = -5.14
Subtract 8.23 from both sides
x = -13.37
2: 4/9x = 32
Multiply both sides by 9 (basically, 4 is being divided by 9, so the opposite is to multiply).
(9 times 4, then divided by 9 is 4)
4x = 288
Divide both sides by 4 to isolate x
x = 72

Answer:
2a. 1/4
2b. 2/8
2c. yes, 1/4 = 2/8 because
2 / 8 = 2 ÷ 2 / 8 ÷ 2 = 1 / 4.
2d. the total number of parts doubled in the denominator, the number of parts represented in the numerator doubled as well.
The operations of division and multiplication are made proportionally to the numerator and denominator.
