Answer:
A
Step-by-step explanation:
A: -a/-b=c (negative number divided by negative number is positive number A is correct)
B: -a x b =c (negative number times positive number is become a negative number so correct answer is -c B is wrong)
C: -a/b=c (negative number divided by positive number is become a negative number so correct answer is -c C is wrong)
D: -a x -b=-c (negative number times negative number is become a positive number so correct answer is c D is also wrong)

Chuin has 18 coins in his pocket. He has nickels and dimes that total $1.45. How many nickels and how many dimes does he have? Write and solve a system of equations to find the answer.
A. 10 Nickles, 8 dimes
B. 9 nickles, 9 dimes
C. 8 nickles, 10 dimes
D. 7 nickles, 11 dimes
Answers
Answer:
D
Step-by-step explanation:
Let n represent the number of nickels and d represent the number of dimes Chuin has.
Since Chuin has a total of 18 coins in his pocket, the sum of the number of nickels and dimes must total 18. So:
[tex]n+d=18[/tex]
The total worth of the coins is $1.45. Since each nickel is worth $0.05 and each dime is worth $0.10:
[tex]0.05n+0.1d=1.45[/tex]
Solve the system. We can use elimination (you can use substitution if you prefer, it works just as perfect!). First, multiply both sides of the second equation by 10:
[tex]0.5n+d=14.5[/tex]
Next, we can multiply the first equation by negative one:
[tex]-n-d=-18[/tex]
Add the two equations together:
[tex](0.5n+d)+(-n-d)=(14.5)+(-18)[/tex]
Simplify:
[tex]-0.5n=-3.5[/tex]
Divide both sides by -0.5. So:
[tex]n=7[/tex]
Chuin has seven nickels.
Using the first equation again, substitute n for 7 and solve for d:
[tex](7)+d=18\Rightarrow d=11[/tex]
Therefore, Chuin has seven nickels and 11 dimes.
Our answer is D.

Step 1. Find the volume of the Son’s chest:
(It is a rectangular prism) 30 x 16 x 24 =
11,520 cubic inches
I used the formula length x width x height.
Step 2. Make an equation to solve for the volume of the chest the daughter will have:
24 x 40 x w = 11,520 in2
11,520 because its said that the two chests should be teh same volume.
Step 3. Multiply the two dimensions of the daughters chest and divide it by the volume of the son’s chest:
11, 520/24 x 40 = 12
We divide it because we use the same formula for the volume of the rectangular prism, so to find the width, divide the length x height by the volume (this is proportionality)
Lets check it:
Volume of daughter’s chest:
12 x 40 x 24 = 11,520
Volume of Son’s chest:
30 x 16 x 24= 11,520
HAVE A NICE DAY
Answer:
12
Step-by-step explanation:
We know that Tyler's chest has a length of 30 inches, width of 16, and a height of 24 inches. To find the volume of the chest, multiply the length by width by height: 24*30*16 = 11,520 in^3 The volume is 11,520.
Juliet's chest will Have a length of 40 inches and the same height as Tyler's chest, or 24 inches. It also has the same volume of Tyler's chest, or 11,520
So Tyler's chest is 24 by 30 by 16 inches, and is 11,520 inches^3
Juliet's chest will be 40 by ? by 24 inches, and will be 11,520 inches^2.
We have to find the width of Juliet's chest. To do that, we have to divide the length times height of Juliet's chest by The volume of her chest, or
11,520/(40*24) = 11,520/960 = 12
Her chest is 12 inches wide

( fraction)
Answers
Answer:
3/8
Step-by-step explanation:
Step 1: Multiply the denominator and the numerator of 1/4 by 2 to get a common denominator between the two. (1/4 and 5/8 is now 2/8 and 5/8)
1*2= 2; 4*2= 8, so you get 2/8 (which is equal to 1/4)
Step 2: When you get 2/8, subtract:
5/8 - 2/8 = 3/8
And... since 2/8 is equal to 1/4, 3/8 is the answer :)
