Rachel has 3 times as many roses as carnations. She has 12 fewer carnations than daisies. There are 15 daisies. How many flowers
horrorfan [7]

Answer:

27 flowers

Step-by-step explanation:

Let

x ----> the number of roses

y ----> the number of carnations

z ----> the number of daisies

we know that

x=3y ----> equation A

y=z-12 -----> equation B

z=15 -----> equation C

substitute the value of z in equation B

y=15-12=3

substitute the value of y in equation A

x=3(3)=9

so

Rachel have 9 roses, 3 carnations and 15 daisies

In total

9+3+15=27 flowers

Find the values of x and y.
Murljashka [212]

ΔABC has two congruent angles. Therefore, it is an isosceles triangle.

Therefore we have the equation (1)  3x - 5 = y + 12.

All angles of the ΔDBC are congruent. Therefore it is an equilateral triangle.

Therefore we have the equation (2)  3x - 5 = 5y - 4

From (1) and (2) we have the equation:

5y - 4 = y + 12      <em>add 4 to both sides</em>

5y = y + 16     <em>subtract y from both sides</em>

4y = 16     <em>divide both sides by 4</em>

y = 4

Substitute the value of y to (1):

3x - 5 = 4 + 12

3x - 5 = 16       <em>add 5 to both sides</em>

3x = 21       <em>divide both sides by 3</em>

x = 7

<h3>Answer: x = 7 and y = 4</h3>

What is the answer
Mrac [35]

Answer:

The coordinates of H′ are (-2,0).

Step-by-step explanation:

It is given that square EFGH stretches vertically by a factor of 2.5 with respect to the x-axis to create rectangle E′F′G′H′.

If a figure stretches vertically by a factor of 2.5 with respect to the x-axis, then the x-coordinates remains same and the points which lie on the axis are also remains the same after stretch.

It is given that the coordinates of H are (-2,0). This point lie on the x-axis, therefore it will remains the same after stretch.

Therefore the coordinates of H′ are (-2,0).
