4)4x+5=17

 5x+5=20

5)2x+15+85+x+20=180

   3x+120              =180-120

                        3x=60

                          x=20 degrees

6)son's age=x

  3x+x=48

   4x=48

    x=12            

Therefore; son's age=12 years old

                  Mr.Robert age=12*3

                                           =36 years old

The cost of 1 oz of chip is $ [tex]\frac{3}{4}[/tex]

Given :

It costs $6 for an 8 oz bag of chips

Explanation

8 oz of chips cost $6

For example , If 5 pencils cost $10

then 1 pencil cost = [tex]\frac{10}{5} =2[/tex]

We are asked to find cost of 1 oz, so we divide the cost by the number of oz

8 oz of chips cost $6

1 oz cost =[tex]\frac{6}{8}=\frac{3}{4}[/tex]

The cost of 1 oz of chip =$ [tex]\frac{3}{4}[/tex]

Step-by-step explanation:

see answer above

Answer:

X= 150º

Y= 60º

(I strongly recommend reading the explanation so you can understand it because its way easier than you think!!)

Step-by-step explanation:

2x+90=5x

-2x        -2x

90=3x

x=30

2(30)+90= 150º

5(30)=150º

Angle x= 150º

Both angles are congruent because they are vertical angles!!

Now we gotta figure out y so you see that there are two lines crossing. (Both sides will work for this) Both angles are supplementary angles which means they combine to make a 180º angle. So if we already know both sides of x are 150º then we can infer that 150+y=180. All you have to do now is subtract 150 from 180 and you will get y.

180º-150º= 30º

Angle y= 30º

But that is not all do not forget that is says (3y)º which means we gotta multiply y by 3.

Sooo 30 x 3 is 60º

Therefore that angle is 60º
