Suppose that you have a stack of pennies. If you want to know without counting whether there is an odd or even number of pennies, then you have to split them into two parts, for example, placing one coin left and one coin right.
If the number of pennies is even, then no coins will left, if the number is odd, then one coin will be extra.
Let the number be x.
Therefore, by the problem
x/6-(-3) = 12
or, x/6+3 = 12
or, x/6 = 12-3
or, x/6 = 9
or, x = 9 × 6
or, x = 54
The number is 54.
10+11+12+13+14(4)+15=117
117/9=13
Final answer: 13
Answer:
3 or 3/1
Step-by-step explanation:
Slope is also known as rise/run.
The formula used to find slope is y^2-y^1/x^2-x^1.
The work is below:
-1-5/0-2
-6/-2
3/1
m=3
When we calculate the slope using the formula, we find that the slope(m) equals to 3/1 or 3 which means that you rise up by 3 and run to the right 1.
