I think it’s x=20 because you multiply both sides of the equation by two and then reduce the numbers with the greatest common factor of 2 and then multiply the numbers
Answer:
8
Step-by-step explanation:
the sum of 5 and 7 is 12
hence, 2/3 x 12 = 8
Answer:
15%
Step-by-step explanation:
Given that,
Initial earning is $20 for each lawn and this summer she raised her price to $23 per lawn. We need to find the percent increase of peggy's charges. It can be given by :
Putting the values in above formula, we get :
So, there is 15% increase in the peggy's charges.
The linear equation for his balance over time is given by:
y = 20x + 100.
- The x-intercept is of 20, which is the amount by which the balance increases each week.
- The y-intercept is of 100, which is the initial balance.
<h3>What is a linear function?</h3>
A linear function is modeled by:
y = mx + b
In which:
- m is the slope, which is the rate of change, that is, by how much y changes when x changes by 1.
- b is the y-intercept, which is the value of y when x = 0, and can also be interpreted as the initial value of the function.
In this problem, he stats the balance with the birthday present of $100, and gets an allowance of $20 a week, hence the equation for the balance after x weeks is given by:
y = 20x + 100.
Hence:
- The x-intercept is of 20, which is the amount by which the balance increases each week.
- The y-intercept is of 100, which is the initial balance.
