The answer would be 1/15.
Find the greatest common multiple of each fraction, then add them. You will get 1/15 out of it.
Question
The exchange rate at the post office is £1=€1.17 how many euros will you get for £280
Answer:
<h2>
327.6 €</h2>
Step-by-step explanation:
you can solve with an equation
1£ : 1.17€ = 280£ : x
1 : 1.17 = 280 : x
x = 1.17 * 280 : 1
x = 327.6
-------------------
check
1 : 1.17 = 280 : 327.6
0.85 = 0.85
the answer is good
------------------------------------
or you can simpy solve with a multiplication
280 * 1.17 = 327.6
Answer:
Step-by-step explanation:
"f (x) = StartRoot 4 x + 9 EndRoot + 2" should be written as
Note that √(4x + 9) is a variation of the basic function y = √x, whose domain is [0, ∞ ).
The domain of f(x) = √(4x + 9) + 2 is found by taking the "argument" 4x + 9 of √(4x + 9) and setting it equal to zero:
4x + 9 ≥ 0, or
4x ≥ -9, or
x ≥ -9/4
This is the domain of the given function f(x) = √(4x + 9) + 2. So long as x is ≥ -9/4, the function f(x) will be defined.
