first work out the value of 2 bags of chips which is: 0.75 + 0.75 = 1.50p
take that away from the total: 22.50-1.50=21 pounds
since what is left (21) is how much 4 ham sandwiches cost we can just divide 21 by 4 which is 5.25
so each sandwich costs 5.25 pounds
U = S ∪ S' = {1, 2, 3, 4, 5}
Answer:
3(8-4x) < 6(x-5)
24-12x < 6x-30
24+30 < 6x+12x
54 < 18x
54\18 < x
3 < x
It means the ans is option no. b
Distribute 1/2 to <span>(n – 4):
</span>


<span>
Subtract (2n + 3):
</span>

<span>
Your equation should now look like this:
</span>

<span>
Combine like terms on both sides:
</span>



<span>
Subtract 1/2n from both sides:
</span>

<span>
Divide both sides by -5/2 to get n by itself:
</span>

<span>
The value of n is
2.</span>
