465 -(-45) = x
This creates a double negative which becomes a positive and you solution would be 465+45 =X, X = 510
It is incorrect because the length of the unknown side is the square root of 7,225.
If you use the pythagorean theorem and plug in the values,
a^2 + 132^2 = 157^2
a^2 + 17424 = 24649
-17424 -17424
_________________
a^2 = 7225
If you square root it, the final answer would be 85.
You forgot to include the diameter and height so I can’t answer it
Answer:
- Abel is 7 and Asare is 17 years old
Step-by-step explanation:
Let the age of Abel is x and age of Asare is y.
Three times the age of Abel is four more than the age of Asare:
And
In three years, the sum of their ages will be 30 years:
We got two equations.
Simplify and solve by substitution:
- 3x - 4 + x = 24 Substitute y
- 4x - 4 = 24
- 4x = 28
- x = 7
Find y:
Answer:
a is -11x+3x
