-x+4y=24 and -2x+y=-8 as an ordered pair

Answers

Answer 1

Answer: (8,8)

Step-by-step explanation:

First you need to get a x or y by itself.

I choosed to get y by itself since it would be faster.

-2x + y = -8  (first get -2x to the other side so add 2x)

y = -8 + 2x (then you want to insert that to the other equation)

-x + 4( -8 +2x) = 24      ->    -x -32 + 8x = 24   ->   7x -32 = 24

(add 32 to the other side)

7x = 56 (divide 7 to 56 to get x) x = 8

now insert into the other equation

-2( 8 ) + y = -8     ->     -16 + y = -8 ( move -16 to the other side, so add 16)

then you get your answer, y= 8

Answer 2

Maura drew a scale drawing of a house and its lot. The scale of the drawing was 1 inch : 2 feet. In the drawing, the porch is 6 inches wide. What is the width of the actual porch? Is it 12???

Answers

Yes, the porch is 12 feet wide.
If 1 inch = 2 feet, and if she makes the porch 6 inches wide, then you multiply the 6inches by 2, since 1 inch is equal to 2 feet.
It is 12 feet ya it is the answer that is it

The distance from Aiden's house to the school is 2.5 miles. The distance from Steven's house to the school is 4,650 feet. Who lives closer to the school? Aiden or Steven? Use numbers and words to explain your answer. Pls Help me :c

Steven lives closer. When you convert 2.5 miles into feet it equals 13,200 that is more than 4,650
