Answer:
After 5 months the cost of the two phones and monthly service be the same.
Step-by-step explanation:
1st service cost = $50 + $40x, where "x" represents the number of months
2nd service cost = $50x
Now we have to find the number of months the cost of the two phones and monthly service be the same.
Now we have to equivate and find the value of x.
50x = 50 + 40x
Subtracting 40x from both sides, we get
50x - 40x = 50 + 40x - 40x
10x = 50
Dividing both sides by 10, we get
x = 50/10
x = 5
After 5 months the cost of the two phones and monthly service be the same.
Hope you will understand the concept.
Thank you.
Let the largest number be x:
smallest number=1/2x
middle number=3/4x
total sum of the numbers is:
x+1/2x+3/4x=252
9/4x=252
solving for x we get
x=252×4/9
x=112
thus the largest number is 112
middle number=3/4*112=84
smallest number=1/2×112=56
Answer: 56,84,112
Once
25 / 16 = 1 remainder 9
or we can write the quotient as 1 9/16
