Ah hah !  This is exactly what I was telling you about in the other answer.

A pair of angles that are formed by 2 lines and DON't share a side are called
"vertical angles", and a pair of vertical angles are always equal.

In this problem, the two angles on the sides facing each other are vertical angles, and that tells you that they're equal.

So you can immediately write         <u> 4y - 8  =  79 + y </u>,

and then you can easily solve that and find the value of 'y' .

nataly862011 [7]

Answer:

Step-by-step explanation:

If you sum everything, you'll get 50 candies. Now you know that 50 candies is 100%.

Now you'll calculate the probability:

12 on 50 : 24.00 %

17 on 50 : 34.00 %

5 on 50 : 10.00 %

6 on 50 : 12.00 %

Hope I was helpful :)

Edit :

a manufacturer of bicycle parts requires that a bicycle chain have a width of 0.3 inch with an absolute deviation of at most 0.0
quester [9]

Answer:

|w-0.3| \leq 0.0003

And solving we got:

-0.0003 \leq w-0.3 \leq 0.0003

0.3-0.0003 \leq w \leq 0.3+0.0003

0.2997 \leq w \leq 0.3003

Step-by-step explanation:

For this case we can define the following notation:

W represent the width

And we want a maximum error of 0.0003 so we can set up the following equation:

|w-0.3| \leq 0.0003

And solving we got:

-0.0003 \leq w-0.3 \leq 0.0003

0.3-0.0003 \leq w \leq 0.3+0.0003

0.2997 \leq w \leq 0.3003

HELP QUICK EASY QUESTION IM JUST DUM
Anna11 [10]

Answer:

10 ÷ 0.2=50

Step-by-step explanation:

10 lbs in total. Each batch uses 0.2 lbs.

We can find how many batches can be made by dividing 10 by 0.2.

10 ÷ 0.2=50

Juan is incorrect because if they could only make 5 batches then they would have only had 1 pound of red dye available.

They have 10 pounds of red dye available to make marbles, and if each batch takes only 0.2 lbs of it, then they can make 50 batches of marbles.
