I need help on the second question
Kay [80]
To get the answer follow the steps below.

All you have to do is add $1,195+$240=$1,435
then divide $1,435÷$100=14.35

So if I'm right the answer would be 15 months and 5 days.

I hope this helps.

What is bigger 7/8 or 0.78
blsea [12.9K]
Solutions 

To solve the problem we first have to convert the fraction into a decimal. To convert a fraction into a decimal you have to divide the <span>numerator</span> by the denominator. 

7/8 
= 7 ÷ 8 
= 0.875 

0.875 is bigger then 0.78 therefore 7/8 is greater.

3. Find x and m_1<br> 3x +8<br> 6x - 22
Sergio039 [100]

Answer:

The answer to your question is: x = 10; 1 = 142°

Step-by-step explanation:

Find x and m∡ 1

We know that         6x - 22 = 3x + 8      Because they are vertical angles

                               6x - 3x = 22 + 8      Solve for x

                               3x = 30

                               x = 10

Then    ∡ = 6(10) - 22

               = 60 - 22

               = 38°

   1 = [360 - 2(38) ] / 2

     = [360 - 76] / 2

      = 284/2

      = 142°
