3 regular bananas weight about a pound.

Which is greater 6km or54,000 mm

Answers

1 km = 1,000,000 millimeters
6 km = 6 * 1,000,000 millimeters = 6,000,000 mm

6,000,000 mm is greater than 54.000 mm

Therefore, 6 km is greater than 54,000 mm,
1km = 1000000mm
6km= 6000000mm
6000000mm > 54000mm
so 6km is greater than 54000mm

Solve this equation. 7.85 + q is less than or equal to -18.15

Answers

7.85+q≤ -18.15

Simplify both sides of the inequality

q+7.85 ≤ -18.15

Subtract 7.85 from both sides

q+7.85-7.85 ≤ -18.15-7.85

Q ≤ -26


I hope that's help !



7.85 + q ≤ -18.15

You can solve this just like any other equation, keeping in mind the inequality sign.

7.85 + q ≤ -18. 15

7.85 + q - 7.85 ≤ -18.15 - 7.85

q ≤ 26

It takes 21 minutes for 5 people to paint 7 walls. how many minutes does it take 3 people to paint 5 walls. Please help.

Answers

It would take 15 minutes.
21/7=3
5/3=1.666666666667
1.6666666667*3=approx. 5
5*3=15 
Hope it hepls :)
It would take 15 minutes.
21/7=3
5/3=1.666666666667
1.6666666667*3= 5
5*3=15 

So if you do 21 divied by 7 that equals 3. then you do 5 divied by 3=1.666666666667 you divide the 3 bc that's the answer you got for 21/7. then you do 1.666666666667 x3. bc you had that answer for the last problem. then you just have 2 multiply 5x3 and that equals 15.
