The number is found by setting up an algebraic equation and solving for x. The solution to the equation (5/11)x = 55 is x = 121.
The problem states: Five elevenths times a number is 55. This is a typical algebra problem. The first step to solve it is to set up the equation: (5/11)x = 55. In order to isolate x to have it by itself on one side of the equation, you divide 55 by 5/11. When we divide a number by a fraction, we multiply it by the reciprocal of that fraction. So, we have x = 55 * (11/5) = 121.

Answer: Jordan worked for 10 hours and Sydney worked for 6 hours.
Step-by-step explanation:
Let x represent the number of hours
that Jordan worked.
Let x represent the number of hours that Sydney worked.
Jordan can iron 20 shirts per hour, and Sydney can iron 25 shirts per hour. They ironed 350 shirts between them. It means that
20x + 25y = 350- - - - - - - - - - - 1
Jordan worked 4 more hours than Sydney. It means that
x = y + 4
Substituting x = y + 4 into equation 1, it becomes
20(y + 4) + 25y = 350
20y + 80 + 25y = 350
20y + 25y = 350 - 80
45y = 270
y = 270/45
y = 6
x = y + 4 = 6 + 4
x = 10
Answer:
x=30
Step-by-step explanation:
2 times 1/2(x+6)=18 times 2
x+6=36
x+6-6=36-6
x=30
whomever is reporting me please stop(echo2155)
Answer:
Step-by-step explanation:
First you have to perform distributive property which is
2((x+6)=18) 2
Which will turn to
X+6=36
Then move the constant to the right so
X=36-6 then calculate
So the answer is 30
The value of x is 30
