Let us take the second equation first
2a + 2b = 6
Dividing both sides by 2 we get
a + b = 3
a = 3 - b
Putting the value of a in the first equation we get
3a + 4b = 9
3(3 - b) + 4b = 9
9 - 3b + 4b = 9
b = 9 - 9
= 0
Now putting the value of b in the second equation we get
a + b = 3
a + 0 = 3
a = 3
So the value of the unknown variable a is 3 and the value of the unknown variable b is 0.
Answer:
3.14 x 10^-7
Step-by-step explanation:
move the decimal behind the first significant figure and count the amount of spaces from there to the original decimal place
Well, it would be 302.1 as three is lowere than five, and when its lower you just leave it. if its five or higher than you round up. hope that helps! :)
