We can add, subtract, multiply, and divide functions just like how we add, subtract, multiply, and divide numbers. To find (f + g)(x) from the given functions f(x) and g(x), we just add the two formulas:
     (f + g)(x) = f (x) + g(x)
     (f + g)(x) = [3x + 1 ] + [x^2 - 6]
Then, we simplify the expressions to
     (f + g)(x) = 3x + 1 + x^2 - 6
     (f + g)(x) = x^2 + 3x - 5
Therefore our answer is x^2 + 3x - 5

What is 0.7, 0.755, 5/8 from least to greatest?
Margarita [4]
I like to start by turning all my numbers into the same form.  You can go either way but I am going to turn the decimals into fractions.  so 0.7 is the same as 7/10.

0.755 is like 755/1000 which can be reduced to 151/200  (if you don't understand the convertions let me know i will explaine more.)

Next give all the fractions a common denominator. both 8 and 10 go into 200 so we can use that.  151/200 already has a denominator of 200 so that one is set.
for 7/10  well, 10 time 20 is 200 so multiply both the numerator and the denominator by 20 so you get 140/200
the last one is 5/8  8 times 25 is 200 so multiply both numbers by 25 to get 125/200  

the fractionos we have are 125/200  151/200 and 140/200.  Now because they all have the same denominator the one with the lowest numerator is the least number and the one with the highest number is the greatest number.

125/200  140/200  151/200  now just replace the original number with the order they are placed in.
125/200 was 5/8
140/200 was 0.7 
151/200 was 0.755
so the final answer is 
5/8, 0.7, 0.755

Alex and Ben were given a total of £240 They shared the money in the ratio 5:7
AfilCa [17]

Answer:

Ben received: £140

Step-by-step explanation:

Total amount = £240

Given ratio: 5:7

It means £240 is divided into 12 parts

So 1 part will be equal to:   £240/12

1 part = £20

Now given ratio is:

5:7

Multiplying each share with £20

5*(£20) : 7* (£20)

£100: £140

So according to ratio amounts:

Alex received:  £100

Ben received: £140

I hope it will help you!
