Estimate whether each sum is closest to 0, 1/2, 1, or 1 1/2.

The sum is closest to 1/2.

Step-by-step explanation:

To simplify it if you make the 1/11 into a 1/10 then it equals 2/10=1/5. 1/5 if way closer to 1/2 than anything else.

y=−9/2x+10

step-by-step explanation:

let's solve for y.

0−9x−2y=−20

step 1: add 9x to both sides.

−9x−2y+9x=−20+9x

−2y=9x−20

step 2: divide both sides by -2.

−2y

−2

=

9x−20

answer: 1722

step-by-step explanation:

given: the mass of saturn=

the mass of mercury=

the number of times the mass of saturn is greater than the mass of mercury

hence, the mass of saturn is 1722 times greater than the mass of mercury.
