Detailed breakdown:
Let’s assume he sold 5 bagels, hence the calculation would be for 5 bagels sold.
12 minus 5 equals 7, thus b equals 7.
Insert into 12 minus 5 equals 7.
b equals 12 minus s.
Answer:
x = 6
Step-by-step explanation:
The equation we need to solve is:
We can change it to exponential form to determine the answer. Below we illustrate the formula to convert log to exponential form:
Next, we convert the log into exponential:
Now we will solve for
Examining Talia's steps to derive the line equation, we identify the erroneous step as detailed below:
Step 1:
Select a point on the line, such as (2,5)
Step 2:
<span>Select another point on the line, such as (1, 3)
Step 3:
</span><span>Measure units to find the slope. The line moves 1 unit to the right and 2 units upward, resulting in a slope of
(5-3)/(2-1) = 2/1 = 2
Step 4:
</span><span>Apply these values in the point-slope form
y - y1 = m(x - x1)
y - 3 = 2(x - 1)
y = 2x + 1
Hence, the conclusion is:
</span><span>Step 4 is erroneous due to incorrect application of (1, 3) in the point-slope format.</span>
Customers served in 0.5 hours : 3.6 versus x customers served in 7.5 hours
-------------------- = --------------------
0.5 hours 7.5 hours
Applying cross multiplication:
3.6 multiplied by 7.5 equals x times 0.5
Dividing both sides by 0.5:
x = (3.6 * 7.5) / 0.5
x = 54
So, you assisted 54 customers in 7.5 hours.
