Answer:

X= 4

Y= -2

Step-by-step explanation:

y - x = 6(1) \\ y + x =  - 10(2) \\  (1) + (2) \\ 2y + x - x =   - 10 + 6 \\ 2y =  - 4 \\ y =  - 2 \\ from(1) \\  - 2 - x = 6 \\  - 2 + 6 = x \\ x = 4

ILL GIVE BRAINLIST ON WHOEVER GETS RIGHT!!!!
tiny-mole [99]

Answer:

The first and third answer I believe.

Step-by-step explanation:

The side with 3 can go over 1.5, since they are both at the same side. It will be equivalent to 4 over 2 because they are also the same side. (1st option)

Multiplying each side by 1/2, does result you to the final image.

3 multiplied by 1/2 is 1.5

4 multiplied by 2 is 2

Suppose that a cyclist began a 374 mi ride across a state at the western edge of the​ state, at the same time that a car traveli
kherson [118]
This is the concept of relative speed; We are required to calculate the speed of the car and the bicycle.
Distance between the car and Bicycle=374 miles
Time they met=5.5 hr
Speed traveled by bicycle=x
Speed traveled by car=x+33.4334
Relative speed=x+(x+33.4334)=(2x+33.4334) mph
Distance=speed*time
374=(2x+33.4334)*5.5
374=11x+183.8837
collecting like term we get:
374-183.8837=11x
11x=190.1163
thus;
x=(190.1163)/(11)
x=17.2833 mph
thus the speed of the bicycle was x=17.2833 mph
The speed of the car was (x+33.4334)=(17.2833+33.4334)=50.7167 mph

Order the following greatest to least <br><br> 1. 10kg<br> 2. 100g<br> 3. 1,000,000mg
svlad2 [7]

Answer:

<em>1, 2, 3</em>

Step-by-step explanation:

Of the three units, the <em>kilogram</em> is the largest and the <em>milligram</em> is the smallest. The prefix “<em>kilo</em>” means a thousand and “<em>milli</em>” means one-thousandths.

1,000,000mg = 1kg  

1kg = 1,000g
