Answer: the number is -3
Step-by-step explanation:
Four times a number is three times the difference of that number and one
Let the number be x. Four times the number means 4×x = 4x
three times the difference of that number and one. This means
Difference of the number and one is (x-1). Three times the difference of the number and one would be 3(x-)
Four times a number = three times the difference of that number and one. Therefore,
4x = 3(x-1)
Opening the bracket
4x = 3x -3
4x-3x = -3
x =-3
Check
4×-3 =3(-3-1)
-12 = -3×4
-12 = -12
So the number is -3
Answer:
Step-by-step explanation:
We can use pytho theorem to find X because its a right triangle, so:
a^2 + b^2 = c^2
plug our numbers
1^2 + 1^2 = x^2
simplify
1+1 = x^2
2=x^2
answer = root2
