3.

When counting significant figures, ignore the 0s that show up before a number more than 0.

If, for example, a number is 0.03067, then there are 4 significant figures, because the first two 0s are ignored but the 0 after 3 is counted!

Sorry if my explanation is difficult to comprehend haha. Please do ask if you’re still unsure

Solve the system using elimination.<br> 5x + 3y = − 8 <br> 7x + 2y = − 20
svlad2 [7]
Your answer should be (-4,4). You would multiply the top row by 2 and the bottom one by -3 to get the y’s the same (both would be 6y) then from there solve for x. once you have x plug in for y.

There are 40 people in a choir.
swat32

9514 1404 393

Answer:

  n = 4

Step-by-step explanation:

Of the 40 people, half are women, so there are 20 women.

There are 5 times as many women as men, so 20/5 = 4 are men.

The remainder are children, so there are 20-4 = 16 children.

The ratio of children to men is ...

  children : men = 16 : 4 = 4 : 1 = n : 1 . . . . . . . . remove a factor of 4 from 16:4

The value of n is 4.
