Answer:
The value of x is 3
Step-by-step explanation:
Given:
To Find:
x = ?
Solution:
We Know that
We can write 27 as 
= 
Taking cube root on both sides
x = 3
Step-by-step explanation:
Every next term is 1/3 times of the previous term. The first term is 4.
Hence the rule is An = 4 * (1/3)^(n-1).
Answer:
1st pair x=-7 and -9; 2nd pair x=2 and y=2; 3rd pair x=-1 and y=0; 4th pair x=-3 and y= 2; 5th x=-2 and y=-1; All others are not clearly written
Step-by-step explanation:
method for simultaneous equation are substitution, elimination or matrix methods
Answer:
x = 107/15
Step-by-step explanation:
Our first step should be to turn all of the mixed fractions into improper fractions. So, 1 2/3 becomes 5/3, and -2 1/5 becomes -11/5. We now get -1/4(x + 5/3) = -11/5. Now we should divide both sides by -1/4, and we get x + 5/3 = -11/5 x -4 = 44/5. So x + 5/3 = 44/5. We want the denominator to be equal on both sides so a common denominator could be 15. 5(5)/3(5) = 25/15. 44(3)/5(3) = 132/15. So now we have x + 25/15 = 132/15. We subtract both sides by 25/15 and we get x = 107/15.
