Answer:
x=-2, y=1. (-2, 1).
Step-by-step explanation:
y=x+3
y=2x+5
------------
x+3=2x+5
3=2x-x+5
3=x+5
x=3-5
x=-2
y=-2+3=1
Answer:
The rate at which how many tokens a person loses per minute.
Step-by-step explanation:
If we move around the terms in the equation to fit standard form, it will be easier to determine the slope.
y = 50 - 2x
y = -2x + 50
We know that the slope is the coefficient of the x variable, so m = -2 or
.
Since the slope is negative, we know that the line will go down as x increases. Since the slope is multiplied by the number of minutes x, we know that the slope represents the typical rate at which a guest spends tokens per minute. In simpler words, how many tokens a person loses every minute.
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
