a) 9 toilet rolls cost $ 4.23
1 toilet roll costs $ x
9x = 4.23 * 1
x= 4.23 / 9
x = 0.47
So in first case one toilet roll costs $ 0.47.
b) 4 toilet rolls cost $1.96
1 toilet roll costs $ x
4x = 1.96 * 1
x = 1.96 / 4
x = 0.49
So in second case one toilet roll costs $ 0.49.
0.47 < 0.49
The toilet roll in first case is cheaper than the toilet roll in second case.
Hope this heps!
I am pretty sure -44 what you have up there is correct.
Answer:
x = 1/7
Step-by-step explanation:
add the two numbers with the x's and subtract 1 from 2. You'll get 7x = 1. Divide 7 from both sides to get x by itself.
Answer:
28
Step-by-step explanation:
Let first integer = x
so second integer = x + 1
according to question we get the equation,,,,
(x) + (x + 1) < 55
x + x + 1 < 55
2x + 1 < 55
subtract 1 from both sides ,we get
2x < 54
divide both sides by 2 we get ......
x < 27
1st integer = x and x < 27
also as we need sum of integer with greates sum so we take x = 26
and 2nd integer = x+1
= 27 + 1
= 28
now if you add both the integers you get sum = 54 which is less than 55 and so this verify you second condtion also .......
hope this will help you
