Answer:Find out the expressions for the number of sweets sue and tony have now .
To proof
As given
Sue has 18 sweets. tony has 18 sweets.sue gives tony x sweets
thus
sue sweets = 18 - x
Tony sweets = 18 + x
As given
Sue then eats 5 sweets. Tony then eats half of his sweets
sue sweets becomes = 18 -5 -x
= 13 - x
Hence proved
Step-by-step explanation:
Answer:
<em>4/15 cups</em>
<em></em>
Step-by-step explanation:
If a cups scientist needs 12 cup baking soda for 45 liter of water, this can be expressed as;
12 cup of soda = 45 litres of water
To get the amount of soda needed for one litre, we will say;
x soda = 1 litre
Divide both equations;
12/x = 45/1
Cross multiply'45x = 12
x = 12/45
x = 4/15
<em>Hence the required answer us 4/15 cups</em>

Step-by-step explanation:
f is (x+1)-1
and g (the next letter in the alphabet) is x-2
first for f
x+1-1 = x
Then we -2 for g
So every letter there o words is just 2 less than the previous letter like
h would be h= x-4
so r(x) is g which is x-2 and x which would have to be the remaining amount to get to the number
