Count using base 13.
In order to get 10, you would have to split the 5 into 2 + 3:8 + 2 = 10 + 3 = 13
In order to get 10, you would have to split the 5 into 2 + 3:8 + 2 = 10 + 3 = 13
10+5+5/2 ten plus five plus five divided by 2
The expression equivalent to 5 plus 3x plus 10 can be simplified by combining the constant terms. Adding 5 and 10 gives 15, so the expression simplifies to 3x + 15. Therefore, the equivalent expression is 3x + 15.
10 + 10 + 10 + 5 + 5 +1 = 41.
One method is (10×4)+(5×3) = 55 (or mentally add up from left to right).
30 + 10 + 5 + 5 = 50
5+5=10 5+5=10 10+10+5=25 so the answer is not 20, it is 25 or 5*5
The lowest common multiple of 2 and 5 is 10, so we try and make the denominators of both these fractions 10. This leaves us with 5/10+4/10. We can add these easily by simply adding the nominators, giving us the final answer of 9/10.
Carry out the addition in base 13 numbers.
9 over 10
25 as 10+10 is 20 plus 5 is 25
