Lubov Fominskaja [6]

Answer: 204 square inches

Step-by-step explanation: I’m not really sure, but if you follow through with the normal area identifying method; Length x Width, you should come up with 25.5. After doing this, you could multiply your product by 8 because your actual mirror size is 8 times greater. You will come up with 204 square inches, which would be your final solution. (Once again, I am not sure, just doing how I’ve been understanding from studies).

Answer:

x=-10

Step-by-step explanation:

15-2(x+5)=25

multiply the 2 by the x and 5 and you get

15-2x-10=25

since the 15 and the negative 10 are on the same side you add them together and get

5 -2x= 25

-5       -5

-2x =20

Then divide the -2/20= -10

Answer:

1. x = 2    y = 1

2. x = 17   y = 29/3

Step-by-step explanation:

1. Use elimination

-4x+3y=-5

4x-5y=3

x's cancel, so add them

-2y = -2

y = 1

substitute

4x -5(1) = 3

4x - 5 = 3

4x = 8

x = 2

2. Use elimination  

2x+3y=36

10x-6y=12

Multiply top equasion by 5

10x+30y = 360

10x-6y = 12

x's cancel so subract

36y = 348

y = 29/3

Substitute

2x+3(2/3)=36

2x+2 = 36

2x = 34

x = 17
