Answer:
1 3/4
Step-by-step explanation: I like math I am smart
Answer: Um It’s C?
Step-by-step explanation:
If the weight of the little brother is x, then the weight of Charles is x + 9
The equation that can be used to determine what each one weighs is:
x + (x + 9) = 99.
Let us now solve it.
x + x +9 = 99
2x + 9 = 99
2x = 99 - 9
2x = 90
x = 90/2
x = 45
Little brother's weight is 45 kg.
Charles' weight will be 45 + 9 = 54 kg
Adding these two weights will give 99kg
The distance between two points can be calculated through the equation,
d = sqrt ((x₂ - x₁)² + (y₂ - y₁)²)
Substituting the known values,
d = sqrt (16 - 2)² + (9 - 2)²)
Simplifying,
d = sqrt (245) = 7 sqrt (5)
The answer is the last choice.
