Answer: 5/9
explanation: the coefficient is in front of the variable x, which is 5/9
A mountaineer climbed 1000 feet at a rate of x feet/hour
1000 = x ( t 1 ) eq1
5000 = X ( t 2) eq2 ( he climbed additional at different rate )
the rate was 10 feet / hour less than twice the first rate
X = 2x - 10 eq3
take eq1 and eq 2
( total time = t 1 + t 2 = T)
T = 1000/x + 5000/X
but X = 2x-10
T = 1000/x + 5000/( 2x -10)
T = 1000/x + 5000/( 2(x-5))
T = 1000/x + 2500 / (x-5)
Answer: X=1
Explanation: When solving an equation, the goal is to isolate the variable (X). In order to do so, you must move everything else on the same side of the equation to the other side. So, in the equation 4=3+x, 3 is on the same side of the equation as X, so you must move it to the other side. When moving a number from one side of an equation to the other, you change the operation to the opposite: “+” becomes “-“, multiplication becomes division. Since the 3 in your equation is positive (+3), when you move it to the other side, it becomes “-3”. Thus:
4-3=x
1=x or x=1
