Answer:

Jenny has 4 pencils.

Step-by-step explanation:

Let

Jenny has pencils = x

Arthur has pencils = 5x+6 (Arthur has 6 more than 5 times the number of pencils as Jenny. )

Total pencils = 30

We need to find how many pencils does Jenny have.

We basically can write the equation:

Total pencils = Jenny pencils + Arthur pencils

Putting values and solving to find value of x:

30=x+5x+6\\30=6x+6\\30-6=6x\\24=6x\\=> 6x=24\\x=\frac{24}{6}\\x=4

So, we have value of x = 4

Now, finding number of Jenny pencils:

Jenny has pencils = x = 4

Therefore, Jenny has 4 pencils.

PLEASE HELP!!!! <br><br><br> What are the missing angles ?
miss Akunina [59]

Answer:

The answer for the first picture is 84

The answer for the second picture is 36

Step-by-step explanation:

The first triangle is a isosceles triangle which means that two angle lengths must be the same. We use the only angle measurement  which is 48 and subtract it from 180 twice because there are two angles lengths that are the same, once we subtract from 180 we have 84. The same process is followed for the second triangle.

180-48-48=84

Second Triangle:

180-72-72=36
