Hi there!
To solve this problem, first we need to convert everything into feet.
1.5 mi = 7920 ft
Since
7920 is greater than 3520,
Ashley lives closer to the school.
Hope this helps!
Answer:
20 + 4 + 40 + 9
Step-by-step explanation:
20 + 4 is 24 and 40 + 9 is 49, so it's pretty much the same thing.
Answer:
X=5
Step-by-step explanation:
Angle A is congruent to angle D.
Given:
f(x) = 70n - 400 : equation for monthly profit.
n = number of students enrolled in the guitar class.
70 refers to the amount charged per student.
400 is the fixed expense made by the instructor.
For the instructor to have a profit, the product of 70n must be more than 400.
400/70 = 5.7 or 6
There must be at least 6 students enrolled in class for the instructor to generate profit.
f(x) = 70(6) - 400 = 420 - 400 = 20
1000 = 70n - 400
1000 + 400 = 70n
1400 = 70n
1400/70 = n
20 = n
There must be 20 students enrolled in class for the instructor to earn 1000 in profit.
1000 = 70(20) - 400
1000 = 1400 - 400
1000 = 1000
Make a guess and check table to figure out if you do not know it off the top of your head.
The answer is 7 and 7
