Answer:
620
Step-by-step explanation:
9.87 is about 10 and 0.509 is about 0.5
(31 * 10) / 0.5 = about 620
<span>Let the larger number be x.
</span><span>A number, y, is equal to the difference of a larger number and 3.
y = x - 3
x - y = 3
</span>The same number is one-third of the sum of the large number and 9.
y = (1/3)(x + 9)
3y = x + 9
x - 3y = -9
The equations are:
x - y = 3
x - 3y = -9
