Answer:
i had it in my head i forgot
Step-by-step explanation:
The answer is 7/10
the 7 is in the tenth place making the denominator a 10 and no same number goes into both 7 and 10.
All you would do is put 23 in the box and put -5 outside and solve
Answer:
The solution to the system of equations be:
(x, y) = (15, -25)
Therefore, the fourth system of equations i.e. 2x+y=5 and 2x – y=55 has the ordered pair (15, – 25) as its solution.
Step-by-step explanation:
Let us solve and check the 4th system of equations
2x+y=5
2x – y=55
solving the system of equations
subtracting
so the system of equations becomes
solve -2y = 50
Divide both sides by -2
Add 25 to both sides
Simplify
Divide both sides by 2
simplify
Thus, the solution to the system of equations be:
(x, y) = (15, -25)
Therefore, the fourth system of equations i.e. 2x+y=5 and 2x – y=55 has the ordered pair (15, – 25) as its solution.
Factor c out (1)
18c^2 - 12cb = c(18c - 12b) then do the numbers
