Let's make an equation.
x+y+z=72
X will be the smallest number. Since they are consecutive, one number is one greater and the other is two greater. Let's make equation for y and z.
x+1=y; the middle number.
x+2=z; the greatest number.
Let's plug these in the equation.
x+x+1+x+2=72
Let's add like terms.
3x+3=72
Subtract 3.
3x=69
Now divide.
69÷3=23
So, the smallest number is 23. So, it must be set a. Let's check.
23+24=47+25=72
So, set a is the correct answer.
The answer is 35.2 because you just have to add them
79+6= 85
85= 8 tens and 5 ones
I rest my case
The number is 1/6. 15 minus 3 = 12. 12 times 1/6 is 2
It is safe to assume the goal is to solve for 'r'. To do so we need to isolate 'r'.
