Answer:
x=-3/19
y=39/19
Step-by-step explanation:
the equations can be written as the following system

If the second equation is multiplied by 3/2 it will become -18x+3y=9
If that equation is then subtracted with the first you will obtain the following
-19x=3, it means x=-3/19
The other variable is obtained by substituting the new value for x in the first equationx+3y=6, thus we obtain that y=39/19
Answer:
160
Step-by-step explanation:
22,000 to 19,000
22,000 - 19,000 / 22,000 x 100
3,000/22,000 x 100
0.136363636363636 x 100
13.63636363636364%
13.64%
14%
Answer:
Here a = 20,, b= 8
Step-by-step explanation:
Using Pythagoras theorem,
a^2 + 15^2 = 25^2 ,, b^2 + 6^2 =10^2=100
Answer:
The first one
Step-by-step explanation:
The first one because the largest exponent is odd and its coefficent is positive
