Paula's Parties sells party supplies such as balloon bunches. The total price for a balloon bunch with j jumbo balloons and m me
Mekhanik [1.2K]

<em>The </em><em>price</em><em> Manuel </em><em>paid </em><em>for the</em><em> balloons</em><em> is</em><em> $17</em>

<h3>The formula for the relation has been given as </h3>4.5j + 2m

where we are told that m stands for medium and

j stands for jumbo.

Here, all we have to do is to make a direct substitution for the jumbo and medium sizes as given in the question.

  1. j = 2
  2. m = 4

Therefore, substituting into the primary equation, we have

4.5(2) + 2(4) =

9 +  8 = 17 dollars

The price Manuel paid to Paula is 17 dollars.

For the parallelogram, if m&lt;2=4x-17 and m&lt;4=3x-8, find m&lt;1.
kompoz [17]

Answer:

D. 161°

Step-by-step explanation:

m<2 is congruent to m<4, m<1 is congruent to m<3 by properties of a parallelogram

to find x:

4x-17=3x-8

x-17=-8

x=9

m<4=3(9)-8=19

so, m<4=19°

m<2 =19°

to find m<1:

the interior angles of a parallelogram add up to 360°

360-2(19)=2x

2x=360-38

2x=322

x=161°

m<1=161°
