Answer:
a) x = -9
b) p = (q - x)/3
Step-by-step explanation:
a) Substitute the values in to the equation
x = 3p + q
x = 3(-2) + -3
x = -6 + -3
x = -9
b) Make p the subject
x = 3p + q
(add 3p to both sides)
x + 3p = q
(subtract x on both sides)
3p = q - x
(divide on both sides)
p = (q - x)/3
Answer:
It will 26 weeks to save for the cruise starting from a balance of $140
(It will take 30 weeks in total, if you start saving from $0)
Step-by-step explanation:
let x = number of weeks
Given starting balance = $140
⇒ 140 + 35x = 1050
⇒ 35x = 1050 - 140
⇒ 35x = 910
⇒ x = 910 ÷ 35
⇒ x = 26
It would be 117800 to the nearest hundred.
