Answer:

5x+2y =-6 ........1

3x-2y = 22 ........2

Add both Equations

we get

8x = 16

Divide both sides by 8

x = 2

Substitute x = 2 into any of the equations

3(2) - 2y = 22

-2y = 22 - 6

- 2y = 18

Divide both sides by -2

y = - 9

x = 2 y = - 9

Hope this helps

Answer:

Reason : by ASA , x = 36

Step-by-step explanation:

∠ABC = ∠EBD (vertically opposite angle)

BC = BD = 54 (same length)

∠BAC = ∠BDE (alternate interior angles)

By ASA , ΔABC ≅ ΔDBE

$54 \times x = 36 \times 54\\\\x = 36$

A rectangular school banner has a length of 60 inches and a width of 48 inches. A sign is made that is similar to the school ban

natulia [17]

Answer:

The ratio of the length of the banner to the length of the sign = 54/17

So....since they are similiar figures, the widths will have the same ratio

And the ratio of the area of the banner to the area of the sign will be the square of this ratio

Step-by-step explanation:

[54/17]^2 = 2916/289

A model rocket is 3 inches long. The real rocket is 120 feet long.

Nana76 [90]

The units are the complete story on this question. All of the choices are over 1 so the units make the answer over one. It takes more feet than it does inches to make the scale. The correct units are 120 feet / 3 inches. That makes A and B both incorrect.

You can't get 360 by any method but multiplication. The units for multiplication would be ft*in. So D is wrong. That only leaves you with C which is the answer.
