500 yards. if the coastguard is 500 yards away from ship and 400 yards away from lighthouse, then it’s the same for the lighthouse
Answer:
$7,000 at 7%; $13,000 at 8%
Step-by-step explanation
x: the amount invested at 7%
y: the amount invested at 8%
x + y = 20,000
7%.x + 8%.y = 1,530
⇒ x =7,000
y = 13,000
Emma distance = x
Mannay distance = 40 in
Relation: 40 in = [4/5] x
Solve for x: x = 5*40in / 4 = 50 in
Answer: option B. 50 inches.
Answer:
(x + 9)(5x - 1)
Step-by-step explanation:
Given
5x² + 44x - 9
Consider the factors of the product of the coefficient of the x² term and the constant term which sum to give the coefficient of the x- term.
product = 5 × - 9 = - 45 and sum = + 44
The factors are + 45 and - 1
Use these factors to split the x- term
5x² + 45x - x - 9 ( factor the first/second and third/fourth terms )
= 5x(x + 9) - 1(x + 9) ← factor out (x + 9) from each term
= (x + 9)(5x - 1) ← in factored form
