6 + 7(b-1) = 5 + b
6 + 7b - 7 = 5 + b
7b - 1 = 5 + b
7b (-b) - 1 (+1) = 5 (+1) + b (-b)
6b = 6
6b/6 = 6/6
b = 1

Answer:
Simple discount notes involve:
proceeds
discount rate
time
bank discount
face value
The main difference is that simple interest is calculated based on principal, whereas simple discount is calculated based on maturity value.
I hope this helps! :)
The way to use the distance formula to classify quadrilateral include:
- Use the distance formula to measure the lengths of the sides.
- Use the slope to check whether the sides are perpendicular and form right angles.
- Use the slope to check whether the diagonals are perpendicular to each
<h3>How to illustrate the information?</h3>
The steps to calculate the perimeter and area of a polygon:
Step 1: Plot the given points on the graph.
Step 2: Connect the points and identify the figure.
Step 3: Determine lengths by counting the grid lines.
Step 4: Use a formula to calculate the perimeter and area if one exists.
Step 5: If there are no formulas for a figure, the perimeter can be calculated by summing the lengths of the sides. We might estimate the area without an area formula by counting the number of small squares enclosed.

Answer:
Step-by-step explanation:
Maria can paddle her canoe 2 miles upstream against the current in the same time it would take her to paddle 6 miles downstream.
Maria can paddle 2mph in still water.
What is the speed of the current?
:
let c = the rate of the current
then
(2-c) = effective speed upstream
and
(2+c) = effective speed downstream
:
Write a time equation; time = dist/speed
Two mi upstr time = six mi downstr time
2%2F%28%282-c%29%29 = 6%2F%28%282%2Bc%29%29
Cross multiply
2(2+c) = 6(2-c)
4 + 2c = 12 - 6c
2c + 6c = 12 - 4
8c = 8
c = 1 mph is the current
:
:
Check this, find the time each way,
effective speed down: 2 + 1 = 3 mph
effective speed up: 2 - 1 = 1 mph
6/3 = 2 hr
2/1 = 2 hrs
