Assume Keesha has d dimes, so she has d + 10 quarters

Total money Keesha has is (d+10)*.25 + d*.1 = 11.25

or 0.35d + 2.5 = 11.25

Solving for d , d = 25

So Keesha has 25 dimes and 35 quarters, total of 60 coins

How to turn 1/4÷9/10 into a mixed fractions

sashaice [31]

First, change the division sign to multiplication, and flip the second fraction

(1/4)/(9/10) = 1/4 x 10/9

1/4 x 10/9 = 10/36

10/36 is your answer, and there is not enough in the numerator to change into an mixed fraction.

hope this helps

Answer:

Nadia's total earnings in month is $3196.1

Explanation:

Given salary of Nadia is $3,300 per month including a 3.25% commission

The salary consists of fixed salary and commission

Therefore, Salary = Fixed salary + Commission

Assume the fixed salary to be x

Putting values in equation

3300 = x + 3.25% of x

3300 = x + $\frac{3.25}{100} x$

3300 * 100 = 103.25x

x = $\frac{3300 * 100}{103.25}$

x = $3196.1 per month

Therefore, the fixed salary of Nadia is $3196.1 per month

To find (fg)(x), you must mult. together the two binomial functions f and g:

(fg)(x) = (6-5x)(6x^2+x = 36x^2 + 6x - 30x^3 - 5x^2

and then you must combine like terms: (fg)(x) = -30x^3 + 31x^2 + 6x
