Answer:

x = -3

Step-by-step explanation:

2x + y = -2

4x + y = -8

2x + y = - 2

y = -2x - 2

4x + y = - 8

y = -4x - 8

y = -2x - 2

y = -4x - 8

-2x - 2 = -4x - 8

4x - 2x = 2 - 8

2x = -6

2x/2 = -6/2

x = -3

To check just use da graph ;w;

The x is -3

Let's give some distances
100 up 100 flat 100 down meters
then return 100 up 100 flat 100 down


time required (distance/rate = time ) 200/100 + 200/120 + 200 / 150 = 5 hr

distance 600


distance / time = average speed = 600/5 = 120 m/s

Please help me to solve this problem
Leto [7]
So you can choose any number from 11 to 19.

I'll choose 11 for now.

Then you write, 11, the number, and then spell it out, eleven.

To show how many tens and ones, you can make a place value chart. You would make two boxes, the first one for tens and the other for ones.

You would put a 1 in the tens place and a 1 in the ones place.

I hope this helps!
