660 ft/min equals 11 ft/sec
Answer: x = 7
Step-by-step explanation:
5x + 7 = 42
We then take 7 away from both sides:
5x = 35
Then, we need to make it so x = answer. To make 5x into x, we divide by 5 meaning that we next need to divide both sides by 5.
x = 7
2x + 6y = 5
x + 3y = 2 .....multiply by -2
-----------------
2x + 6y = 5
-2x - 6y = - 4 ...(result of multiplying by -2)
----------------add
0 = 1 (incorrect).......no solutions because the lines are parallel.
little tip :
if ur system of equations comes out where it is not equal....like 4 = 5, or 6 = 7...then there is no solutions.
if ur system of equations comes out where it is equal...like 5 = 5 or 8 = 8, then there is infinite solutions
if ur system of equations comes out where a variable = a number....like x = 2 or y = 5.....then there is one solution
The missing number would be 4/6, or 2/3.
The missing number can be found by finding the absolute distance in between the numbers, dividing it and then adding it to the smaller number.
(5/6-3/6)/2=(2/6)/2=1/6
3/6+1/6=4/6 or 2/3
