Step-by-step explanation:
Answer: Percentage decrease = 20% × 7,720
New value = 7,720 - Percentage decreaseNew value =
7,720 - Percentage decrease =
7,720 - (20% × 7,720) =
7,720 - 20% × 7,720 =
(1 - 20%) × 7,720 =
(100% - 20%) × 7,720 =
80% × 7,720 =
80 ÷ 100 × 7,720 =
80 × 7,720 ÷ 100 =
617,600 ÷ 100 =
6,176
New value - 7,720 =
6,176 - 7,720 =
- 1,544

Answer:
(x) =
Step-by-step explanation:
let y = g(x) and rearrange making x the subject
y = x - 9 ( add 9 to both sides )
y + 9 = x
Multiply both sides by 5 to clear the fraction
5y + 45 = 3x ( divide both sides by 3 )
= x
Change y back into terms of x, thus
(x) =
