<span>(A) formulate an equation for x: A$100= S$(65-5) So A$100= S$(60) So A($100)/60 = S$(60)/60 THEN A(1.66)= S$(1) (B) find the value of x: (By the previous equation provided x = ((A$100)/(S$))+5 (C) find the amount of Singapore dollars mr neo received if he exchanged A$125 in November 2013: IF A$(1.66)=S$(1) then A$(1.66x125)= S$(207.50) Thank you!</span>
Answer:
x + 0.25
Step-by-step explanation:
In this equation, x is representing an integer ( - 0.5, - 0.75, 0, 0.25) whilst 0.25 is a constant
The smallest number of the group is .103
Set up a proportional relationship:
xf/1n=(f/5)/(n/3)
xf/1n=3f/(5n) multiply both sides by 1n
xf=3f/5 so
x=3/5
Dave must mix in 3/5 of a cup of fruit with a single cup of nuts.
You could of also just noted that you need to multiply 1/5 times 3 because 1/5 mixes with just 1/3 of a cup of nuts...
Step-by-step explanation:
The domain of the function is the range of x-values, which is -5 <= x <= 5. (D)
