Converting to base 10 can be done easily by writing a sort of digit expansion. In base 6, this number literally means
Simplifying this gives the value in base 10.
Step 2 9y - 24 = 10 + 3y because 3 times 3y its not 6y nor is 3 times 8 equal to 5
No because 62122 can not be simplified
Answer:
x=-7/3
Step-by-step explanation:
-6x-7=7
-6x=7+7
x=-14/6
x=-7/3 or in mixed fraction
x=-2 1/3
Answer:
see below
Step-by-step explanation:
0 = x^2 + 6x – 10
Add 10 to each side
10 = x^2-6x
Take the coefficient of x
-6
Divide by 2
-6/2 =-3
Square it
(-3)^2 =9
Add 9 to each side
10+9 = x^2-6x+9
We use -3 for the square term
19 = (x-3)^2
Take the square root of each side
±sqrt(19) = x-3
Add 3 to each side
3±sqrt(19) = x
