Answer:

x = 21/2

y = -19/2

Step-by-step explanation:

5x - 17 = 4y + 7x

5x - 7x - 4y = 17

-2x - 4y = 17

6x + 8y = - 13

-2x - 4y = 17 | ×2 |

6x + 8y = - 13 | ×1 |

-4x - 8y = 34

6x + 8y = - 13

___________+

2x = 21

x = 21/2

-2x - 4y = 17

-2(21/2) - 4y = 17

-21 - 4y = 17

-4y = 17 + 21

-4y = 38

y = -38/4

y = -19/2

Draw a line from each figure to an area
Georgia [21]

Answer:

A=27 cm^2

B=24 cm^2

C=26 cm^2

D=28 cm^2

Step-by-step explanation:

Break each problem down into individual shapes.

For instance, A can be split into a 3 by 3 square and a 6 by 3 square.

      Get the area by multiplying the length & height: A = L * H

For the triangles the area is the same equation divided by 2 A=LH/2

Shapes with unclear dimensions like C can be skipped and have their area revealed through process of elimination.
