Answer:
Step-by-step explanation:
The student currently has $50 and plans to save $15 every month.
Let x represent the number of months that the student will save enough money to buy the microscope.
Let y represent the amount that the student saves after x months.
The function that represents the amount y (in dollars) of money that the student saves after x months will be
y = 50 + 15x
The 50 remains constant because she has already saved it
Answer:
7.5 miles
Step-by-step explanation:
5 miles in 80 km
Total distance = 120 km
120- 80= 40 km
80 km = 5miles
1 km = 5miles/ 80km
120 km = 5/80 * 120 km = 7.5 miles
This is called unitary method. First we find 1 km by dividing the miles with the number of km and then multiply the number of km to find the total number of miles.
Total distance = 120 km
120- 80= 40 km
if there are 5 miles in 80 km then there will be half of the miles in half of the km . So there will be 2.5 miles in 40 km .
So the total number of miles would be
40+80 km= 5+ 2.5 miles
120 km = 7.5 miles

Answer:
Step-by-step explanation:
x² - 17x + 72 = 0
Sum = -17
Product = 72
Factor = 8 , 9
x² - 17x + 72 = 0
x² - 8x -9x + (-8)*(-9) = 0
x(x - 8) -9(x -8) = 0
(x - 8 ) (x - 9) = 0
Length = (x - 8) units
Width = (x - 9) units
