Plzzzzz help 3 9/10 is the same as the sum of 3 1/3 and half of a number what is the number​
kirill [66]

Answer:

9/10 = 1/3 + 1/2x

9/10 - 1/3 = 1/2x

LCM of 10 and 3 is 30

( 27 - 10)/30 = 1/2x

17/30 = 1/2x

17 * 2 = 30x

34=30x

34/30= 30x/30

x = 17/15

Find the values of the variables for the parallelogram if m<1=4y-2. Round your answers to two decimal places if necessary!
hichkok12 [17]

The prallelogram whose adjacent sides are equal and one vertex angle is 90 degrees is a square.

The value of angle 1 is 90 degrees as the diagonal of the square intersect at 90 degrees.

\begin{gathered} 4y-2=90 \\ 4y=92 \\ y=23 \end{gathered}

The value of y is 23.

The diagonal of the square bisect the vertex angle hence the angle of 3x is 45 degrees.

\begin{gathered} 3x=45 \\ x=15 \end{gathered}

Thus, the value of x is 15 degrees.

The value of 12z is 45 degrees.

\begin{gathered} 12z=45 \\ z=3.75 \end{gathered}

Thus, the required value of z is 3.75 degrees.

Mei does 6 problems in 18 minutes. How many can she complete in 12 minutes
Dmitriy789 [7]
Do cross multiplication

  <u>6</u>  =  <u>x</u>
 18    12

Now cross multiply

(6)(12) = (18)(x)

       72 = 18x

Divide both sides by 18
     
    
     <u>72</u>  = <u>18x</u>
     18      18

      4   = x

So tMei can complete 4 problems in 12 minutes.
