Answer:
£9.80
Step-by-step explanation:
The computation of the total value is shown below:
Given that
The value of 20p coins is £2.80
So the value of 50p would be
= £2.80 × 50 ÷ 20
= £7
Now the total value is
= £2.80 + £7
= £9.80
Answer:
∠ KLM = 27°
Step-by-step explanation:
∠ KLM + ∠ NLM = 90 , that is
3x + 7x = 90
10x = 90 ( divide both sides by 10 )
x = 9
Thus
∠ KLM = 3x = 3 × 9 = 27°

The answer is A in my opinion
Answer:
Here's what i know:
x + y = 23
3y / 20 =x
Here we can use substitution to help find our answer:
y + 3y/20 = 23
20y/20 + 3y/20 = 23
23y/20 = 23
23y = 23 * 20
y = 23 * 20 / 23
y = 20
x + 20 = 23
x = 3
