Answer:
Step-by-step explanation:
t=3
A = Andrew
S = Sister
A : S
2 : 3
2 + 3 = 5
250 ÷ 5 = 50
2 × 50 = 100
3 × 50 = 150
∴ A : S
100 : 150
So Andrew keeps £100 of his salary every week.
Of this, he saves 12%:
100 × (12 ÷ 100) = 12
So he saves £12 every week
360 ÷ 12 = 30
∴ it will take him 30 weeks to save £360.
So what do l need to answer here ( the question is incomplete)
BC must be equal to AD, so 4x+5=-3x+26. You must get all common terms on one side, so 7x=21. then divide to get x alone, and x=3.
