Answer:
System of equations:
A bar soap costs $0.52 and a sponge costs $0.15
Step-by-step explanation:
Let be "x" the cost in dollars of a bar of soap and "y" the cost in dollars of a sponge.
Based on the information given in the exercise, you can set up the following system of equations:
You can use the Elmination method to solve the system of equations:
1. Multiply the first equation by -3 and the second one by 5.
2. Add the equations.
3. Solve for "x".
Then:
4. Substitute the value of "x" into any original equation and solve for "y":
The correct answer is the first option, which is:
5(x+3)(x-3)
The explanation is shown below:
1. To solve the problem shown in the figure attached, and factor the given equation, you must apply the following proccedure:
1.You have the following equation given in the problem: 5x^2-45. As you can see, it is a quadratic equation.
2. When you factor it, you obtain:
5(x^2-9)
5(x+3)(x-3)
3. Therefore, the answer is the optiones mentioned before.
Answer: $4,800
Step-by-step explanation:
(Assuming the interest is calculated monthly)
1. 6% of $40,000 = $2,400
2. $2,400 x 2 months = $4,800
3. Total value of account = $44,800; $4,800 is from interest
31 bro because if you think about it 8 times 4 is 26 + 5 more equals 31 c
I think it's ¥1000 for $100, I'm not sure how yen works.
