Answer:

She will have 19 ¹/₂ batches of purple paint

Step-by-step explanation:

<em>r </em>+<em> b </em>= 1<em> bp</em>

³/₄ <em>r</em> + ³/₄ <em>b </em>= 1<em> bp</em>

(³/₄ + ³/₄) * 13 = <em>x bp</em>

⁶/₄ = 1 ¹/₂

1 ¹/₂ * 13 = 13 ¹³/₂ = 19 ¹/₂ batches

VARIABLE KEY:

<em>r</em> = red

<em>b</em> = blue

<em>bp</em> = batches of purple

<em>x</em> = total number of <em>bp</em>

Good luck!!

She will have 19.5 cups of purple paint.
I couldn’t write the explanation of how you get the answer, but look your question up on Brainly and it’ll give you your explanation.

Hope this helped! :)

Answer:

  • x = 7
  • y = 97°
  • z = 19

Step-by-step explanation:

The markings on the figure show this to be a parallelogram. That means opposite sides are congruent. Because the sides are parallel, "alternate interior" angles are also congruent.

__

Angle y forms a linear pair with the one marked 83°, so is supplementary to it:

  y = 180°-83° = 97°

__

The angle marked y is an exterior angle to the triangle containing the angle marked (7x -5)°. As such, it is equal to the sum of the remote interior angles, the one marked (7x -5)° and the unmarked one that is congruent to (3x +32)°.

  (7x -5) +(3x +32) = 97 . . . . . angle relations in the left-side triangle

  10x +27 = 97 . . . . . . . collect terms

  10x = 70 . . . . . . . . subtract 27

 x = 7 . . . . . . . . divide by 10

__

The side marked Z is congruent to the opposite parallel side, so ...

  z = 19

__

The missing measures are ...

  • x = 7
  • y = 97°
  • z = 19

_____

<em>Additional comment</em>

You can also find the value of y by adding up the interior angles of the right-side triangle. The one not shown there is "alternate interior" to the one marked (7x -5)°, hence has the same measure. This gives ...

  (7x -5) +(3x +32) +83 = 180

Subtracting 83° from both sides gives the equation we used above.

ou originally draw a design for an art contest on a 2 in. x 5 in. card. The second phase of the contest requires the drawing to
valentina_108 [34]

Since the largest size of one of the dimensions is 10.5, it has to correspond with the long side of the card, the 5 in. side. To find the proportion of the sides, divide 10.5 by 5. Then, multiply the other side of the card by the quotient.

10.5/5 = 2.1

2.1 * 2 = 4.2

4.2in is the shorter side. Your question asks to round to the nearest tenths, the smallest place value of the answer is already the tenths place.
