Devon has 14 steel balls of equal weight. If he puts 8 of them in one pan of a balance, and the rest along with a weight of 20 g

rams in the other pan, the pans balance each other. Which equation can be used to find the weight of each steel ball?

14-8=6, so 8 balls balance with 6 balls and 20 grams. From this you know that 2 balls=20 grams, simply divide this by 2 to get the weight of one ball which will weigh 10 grams.

Okay so first to solve this lets set up our equation...

Devon has 14 balls of equal weight
14

8 of them go in one pan
14 - 8 = 6

6 goes in another pan along with a weight of 20 grams

So if we assume each ball is 10 grams then the 6 plus 20 grams would equal 8 balls.

This would balance it out.

8 balls of 10g - 6 balls of 10g and a 20g weight

So each ball would weigh 10 grams

Hope this helped. Have a great night!

What is the angle of B
Charra [1.4K]
Y-9 + y/2 = 180
Add nine to each side
y+y/2=189
Multiply each side by two
2y+y=378
Add the y's together
3y=378
Divide it all by three
y=126

so, Angle B is 126 degrees

I hope that helps!

Answers:

Upper Limit = 2.55 cc

Lower Limit = 2.25 cc

cc stands for "cubic centimeters".

==========================================

Explanation:

The tolerance tells us how much we can go over or under our target. It's our margin of error. We add and subtract the tolerance (0.15) from the target we're trying to aim for (2.4)

So the lowest dosage allowed is 2.4-0.15 = 2.25 cc

The highest dosage allowed is 2.4+0.15 = 2.55 cc

The upper limit is 2.55 cc while the lower limit is 2.25 cc

On a number line, we would find that 2.4 is at the midpoint of 2.25 and 2.55; so its at the center of those lower and upper bounds. The distance from the center to each endpoint is the same. That distance would be the tolerance 0.15
