Answer:

The solution is  x = 9, y = -1.

Step-by-step explanation:

x + y = 8

x -  y = 10       Adding to eliminate y:

2x + 0 = 18

x = 9               Substituting x = 9 into the first equation:

9 + y = 8

y = 8 - 9

y = -1..

Is 30,000 L bigger than 3 kL
Ksivusya [100]

Yes it is. 1 kiloliter = 1,000 liters.

Therefore, since 2 kL = 3,000 L

30,000 L > 3,000 L


Remember kilo always means 1,000.

Hope this helps,

If two angles form a linear pair and the measure of the first angle is one-fifth the measure of the second angle, what is the me
kari74 [83]

Well, one angle has one share of the linear angle, and the other one has five shares. All together, they add up to six shares of the linear angle.

BUT ... a linear angle adds up to 180°. So each share must be (180°/6) = 30°.

The smaller one (one share) is 30°, and the larger one (5 shares) is 150°.
