A number a decreased by 7 is 2.

umka21 [38]

Answer:

Step-by-step explanation:

Let's first convert this to numbers. When a number is decreased by a certain amount, that is the same as saying that something is subtracted from it. Therefore:

Add 7 to both sides:

a-7+7=2+7

a=9

Which is bigger 0.17 or 0.165

Bogdan [553]

0.17 is bigger because you compare the values of the number in each place. There is no whole number, the tenths place is equal. Then in the hundredths place you have a 6 and a 7. 6<7 so therefore 0.17> 0.165. To help yourself out u can add a 0 at the end to then more easily compare .170 to .165
