First you have to get the same variables on one side so you’d subtract 5.1w from both sides, making the equation -0.6w = -30
then you want to single out the variable, diving -0.6 on both sides making the new equation and the answer w = 50
hope this helps!
If we are eliminating x, we would multiply the 2nd equation by -5
5x + 18y = 23
x + 3y = 2....multiply by -5
-----------------
5x + 18y = 23
-5x - 15y = - 10 (result of multiplying by -5)
----------------add
0 + 3y = 13.....bye-bye x :)
Answer:
The answer is : 2/3
Step-by-step explanation:
2+9x^2=6
9x^2 = 6 - 2
9x^2 = 4
x^2 = 4/9
x = √(4/9)
x = 2/3
If the distance around the earth means circumference, it is, 24,887.64.(not rounded.) C=pi D (pi=3.14 + d=diameter)
