One solution. Hope this helps!
Answer:
3. x = 53
4. x = 60
Step-by-step explanation:
63 = 0.63×10² = 126/2 = 3×21 = √3969 = 77₈
The last is as a base-8 number.
79 /6 =
6 goes in to 79 13 times with 1 left over
13 1/6
each of the six friends get 13 cards and there is 1 left over that no one gets(unless they divide the card into 6 pieces)
To factor this equation out, the easiest way is to solve for the two x values that add up to -1 but when multiplied is equal to -6. It should look like this: (x +- ?)(x +- ?).
The factored out form is then (x - 3)(x +2), because -3 + 2 = -1 and when multiplied together gives -6.
x - 3 = 0
x = 3
x + 2 = 0
x = -2
The two solutions are therefore, x = 3 and x = -2.
