Every evening Jenna empties her pockets

Mathematics
1 answer:
rodikova [14]2 years ago
3 0

Answer:

15

Step-by-step explanation:

1 dime = 10

1 quarter=25

x=number of coins - dimes

y= number of coins - quarters

x (10)+y(25)=10.25

x+y=50

x= 50-y

x(10)+y(25)=1025

(50-y)(10)+25y =1025

500-10y+25y=1025

500+15y=1025

15y= 1025 - 500

15y=525

y=525/15

y=35

x= 50-35=15

I do not know how to solve this please help
oksano4ka [1.4K]
You multiply the denominator on one side of the equation by the numerator and vice versa. So for example(S)I'm going to multiply 4 by nine and 3 times n. Then that comes out to 3n=36. After you multiply, you divide from both sides to get the variable by itself. So you would divide both sides by 3 and you're final answer would be n=13. Hope this helped!

Answer:

Step-by-step explanation:

The length of a string is given in yards, is a function f(n) of the length n in inches.

We have to write a function rule for this situation.

∵ 36 inches = 1 yard

∴ 1 inch = 1/36 (yard)

∴ n inches = n/36

and function representing the length will be

f(n) = n/36
