$1750 x 21 days = $36,750 for her daily article

9.72 x 3 weeks = $29.16

$36,750 - $29.16 = $36,720.84

balance = $36,720.84

if Martha is not earning money to pay it back, it would be negative. Each week, she loses -9.72 dollars. so -9.72 x 3 weeks = your problem. I'll let you take it from there and solve the rest

If the mean of 5 positive integers is 15, what is the maximum possible difference between the largest and the smallest of these
Vikki [24]

Answer:

if the 5 numbers are different, the maximum difference is 64

Step-by-step explanation:

We have 5 positive (different) integers, a, b, c, d and e (suppose that are ordered from least to largest, so a is the smallest and b is the largest.

The mean will be:

M = (a + b + c + d + e)/5 = 15.

Now, if we want to find the largest difference between a and e, then we must first select the first 4 numbers as the smallest numbers possible, this is:

a = 1, b = 2, c = 3 and d = 4

M = (1 + 2 + 3 + 4 + d)/5 = 15

M = (10 + d)/5 = 15

10 + d = 15*5 = 75

d = 75 - 10 = 65

then the difference between a and d is = 65 - 1 = 64.

Now, if we take any of the first 4 numbers a little bit bigger, then we will see that the value of d must be smaller, and the difference between d and a will be smaller.

[PLEASE ANSWER ASAP] The entrance fee to a circus for a child is RM(3x-y). The entrance fee for an adult is RM2y more than the e
Vinil7 [7]

The total cost that will be paid by the family will be RM(15x - y).

<h3>How to calculate the cost?</h3>

The entrance fee to a circus for a child is RM(3x-y).

The entrance fee for an adult is RM(3x - y) + RM2y = 3x + y.

Therefore, the cost for 2 adults and three children will be:

= 2(3x + y) + 3(3x - y)

= 6x + 2y + 9x- 3y

= 15x - y

The ratio of SAMs age to hank is 5 to 3. If the sum of their age is 24. How old is is hank?
Serggg [28]
Lets consider SAM's age is 'x'  and Hank's age is 'y'
So as per given data Sam's age is 5/3 times of Hank's age
so x = 5/3 * y
3x = 5y --> equation 1
 and also sum of their ages is 24
so, x + y = 24
we need to find Hank's age (y)
so x = 24 - y
Now replace x value in equation 1
3(24-y) = 5y
72-3y = 5y
72 = 3y+5y
8y= 72
y= 72/8
y = 9 years.

So the Hank's age is 9 years
