The age of Kwaku is 8 years old , Esi is 13 years old and Kojo is 26 years old.
<h3>What is an Equation ?</h3>
An equation is a statement that contains algebraic expressions equated by an equal sign with constants or other variables.
Let the age of Kwaku is x
Let the age of Esi is y
From the given data
The age of Kojo is 2y
y = x +5
Sum of their age = 47
2y = 2x +10
therefore the equation formed is
x + y +2y = 47
x + x+5 + 2x +10 = 47
4x +15 = 47
4x = 32
x = 8
y = 13
2y = 26
Therefore Kwaku is 8 years old , Esi is 13 years old and Kojo is 26 years old.

2.75/1.1=2.50
Therefore, the main bill was two and a half dollars
Answer:
About 1.936
Step-by-step explanation:
First evaluate the function like you would any other function by plugging in 3/2 for x.
f(3/2)=4(3/2)-(3/2)^2
f(3/2)=6-2.25
f(3/2)=3.75
Now, find the square root of 3.75
√(3.75)≈1.936 The square root of f(3/2) is approximately 1.936
A) multiple the 3 x 4 and add 1.
3 x 4 = 12 + 1 = 13
13/3
B) (7 x 3) + 2 = 23/3
C) (4 x 2) + 1 = 9/2
D) (2 x 8) + 7 = 23/8
