Shade in twenty one hundredths and two tents on the other but put the twenties in columns
You have to add the 2 yards together... 5,215 + 1,850 = 7,065. If 2 bags will cover 2,500 square feet, then 1 bag will cover 1,250. Divide 7,065 by 1,250 and you will need 6 bags of seed. For problem 2, add all the purchases together, which will be $250.50. This will get him a 30% discount. So his total price after the discount will be about $175.35. For problem 3, this is an exponential function. The $10,000 loan with 9% rate over 5 years is equal to 10,000(1+0.09)^5 which is about $15,500, so he will have to pay an additional $5,500.
Step-by-step explanation:
y + 4 = -2x + 2
2x + y = -2
2x = -2 - y
x = -2 -y/2
Answer:
x= 4 or -10
Step-by-step explanation:
Answer:
440 students.
Step-by-step explanation:
Given is a table showing the results of a survey.
No of people surveyed = n (say)
No of people who prefer pop music = (5/8) n
(Since given in the table proportion for pop music = 5/8)
But actual studdents who prefer pop music =275
In other words
5n/8 = 275
Cross multiply to solve
5n=2200
divide by 5
n= 440
Thus total people surveyed= 440
Verify:
No of students who prefer Pop music = 440(5/8) = 55(5) = 275
Thus verified
