What are you trying to solve for?
There is a 1/4 chance to pull a non-yellow card
x = # of weeks
y = total amount of money
Your savings account: $122 + $12x = y
Your friend's savings account: $92 + $17x = y
As the question suggests, we need to set both equations equal to each other.
$122 + $12x = $92 + $17x
Subtract $92 from both sides and subtract $12x from both sides.
$30 = $5x
Divide both sides by $5
6 = x
It will take 6 weeks for you and your friend to have the same balance.
Answer:
y = 3x - 5
Step-by-step explanation:
1. The slope-intercept form a line is y = mx + b, where y = y-coordinate, m = slope, x = x-coordinate, and b = y-intercept.
2. Given the values of m and b, let's plug them in:
Therefore, the equation of the line in slope-intercept form is y = 3x - 5.
Have a lovely rest of your day/night.
The sum of x and 9 divided by 2 is equal to 3x
(x + 9)/2 = 3x
Note the equal sign, what you do to one side, you do to the other. First, multiply 2 to both sides
(x + 9)/2(2) = 3x(2)
x + 9 = 6x
Subtract x from both sides
x (-x) + 9 = 6x(-x)
9 = 5x
Isolate the x. Divide 5 from both sides
9/5 = 5x/5
x = 9/5
9/5 is your answer for x
hope this helps
