Answer:
50 coins
Step-by-step explanation:
We are given £1 worth of 20p coins.
Since it is known that,
£1 = 100p
i.e. £10 = 100 ×10 p = 1000p
As, we are taking 20p coins to get make the sum 1000p.
Thus, the number of 20p coins will be 
i.e. 50 coins
Hence, we get 50 coins to make £10 worth 20p coins.
4 divided by 1 out of 3 is equal to an unknown value solve for the unknown value
7x(√x - 7√7) Multiply √7x to "√x" and "-7√7" respectively:
√7x*√x - 7√7*√7x
First is to simplify: √7x² - 7√7²x
Extract the squares: x√7 - 7*7√x
Then, we simplify: x√7 - 49√x
After simplifying the equation, I got the answer x√7 - 49√x.
Answer:
Its 5,...................
Answer:
a) Angle XBC = 55 because XY is parallel with BD
b) As given, XB = XC, so that triangle XBC is the equilateral triangle.
As XBC is equilateral triangle, angle XBC is equal to angle XCB
Angle XBC = 55° => Angle XCB = 55°
In a triangle, the total value of three corners are equal to 180°
So that: Angle XBC + Angle XCB + Angle BXC = 180°
=> 55° + 55° + Angle BXC = 180 °
=> Angle BXC = 70°
