845 because 800 is greater than 700 and 845 is an odd number because it ends in 5 (which is an odd number).
That is false because you have to subtract the exponents not divide
First number: x = 19
Second number: Y = -5
x + 2y = 9
2x + y = 33
The answer would be A. Radical sign 3.
Answer:
Her son is 10 years old.
Step-by-step explanation:
Let son be x
Ellie is 4x
In 5 years time: Her son = x + 5
Ellie = 4x + 5
Given that she will then be 3 times as old as her son: 4x + 5 = 3(x + 5)
Solve x: 4x + 5 = 3(x + 5) ,4x + 5 = 3x + 15
x = 10
