Ana María had $28,000 to invest. She divided the money into three different accounts. At the end of the year, she had made $1,160 in interest. The annual yield on each of the three accounts was 3.5%, 4.25% and 4.75%. The amount of money in the 4.75% account was 75% of the amount of money in the 3.5% account. Define variables and write systems of equations to represent the situation. Solve the system to determine how much was put into each account.
Answer:
x + y + z = 28,000
0.035x + 0.0425y + 0.0475z = 1160
z = 0.75x
Step-by-step explanation:
Let x = amount invested at 3.5%.
Let y = amount invested at 4.25%.
Let z = amount invested at 4.75%.
The total amount is $28,000.
Equation 1:
x + y + z = 28,000
The total interest is $1,160.
Equation 2:
0.035x + 0.0425y + 0.0475z = 1160
"The amount of money in the 4.75% account was 75% of the
amount of money in the 3.5% account."
Equation 3:
z = 0.75x
The system of equations is:
x + y + z = 28,000
0.035x + 0.0425y + 0.0475z = 1160
z = 0.75x
Answers to the system of equations:
The total amount in each account is:
x = $8,000
y = $14,000
z = $6,000
Part B
Create an equation modeling the given situation that matches the balance scale.
Answer:
Team A, Team B, and Team C collected 12 pounds of trash in all.
Team A + Team B + Team C = 12
Team B collected 3 pounds of trash and team C collected 5 pounds of trash.
Let the amount of trash collected by Team A be x.
So, x+3+5=12
This can be simplified as x+8=12

Point S is on line segment RT. Given RT
15 and ST = 3, determine the
length RS.
Answer:
RS=12
Step-by-step explanation:
The whole line is 15 units
part of the line is 3 units
the part of the line without measure would be
15 - 3 units so 12 units
The length of RS is 12 units.
What of line segment?An area or portion of a line with two endpoints is called a line segment. A line segment, in contrast to a line, has a known length.
A line segment's length can be calculated using either metric measurements like millimetres or centimetres, or conventional measurements like feet or inches.
Given:
RT = 15 and ST = 3.
So, according to the given information
RT= RS + ST
15 = RS + 3
RS = 15-3
RS = 12
Hence, the length of RS is 12 units.

The expression 3y−24 factored using the GCF is
Answer:
the answer is y equals 8
Answer:
y - 8
Step-by-step explanation:
All you need to do is find the GCF.
First you line up all of the factors and then find the common factor that is the biggest you can find.
3 : 1, 3
24 : 1, 2, 3, 4, 6, 8, 12, 24
Once you find the GCF then you can divide them by it,
3/3 = 1
24/8 = 8
Then you turn the one into y.

Find his gain percent
Given parameters:
Cost price of the article = Nu.28.30
Selling price of the article = Nu.29.30
Unknown:
Gain percentage = ?
The gain percentage is the same as the percentage profit on a trade.
The formula is given as:
Gain percentage = [tex]\frac{Profit}{Cost price} x 100[/tex]
Profit = Selling price - Cost price
= Nu.29.30 - Nu.28.30

Answer:
What is the difference between metric and English system of measurement?
Step-by-step explanation:
Conversion Ratio (or Unit Factor): While the Metric System simply moves the decimal point to convert between its measurements' prefixes, the English System requires a conversion ratio (or unit factor) to move between measurements. In the Metric System, the prefix itself gives the needed conversion ratio.

The garden has 8 pots. There are 2 flowers in each pot. Mark multiplied 8 x 8 to find the total number of flowers. Emma multiplied 2 x 8 to represent the number of flowers. Explain your thinking about who is correct by writing it in complete sentences.
Answer:
Emma is correct. There are 8 pots and two flowers in each pot, so 8 pots times 2 flowers per pot equals 16 flowers. Mark calculated how many pots there would be total if there were 8 gardens with 8 pots each, or how many flowers total if there were 8 pots with 8 flowers each.
Step-by-step explanation:
Answer:
Emma is correct because there are 8 pots and each of those 8 pots has 2 flowers inside it. I hope this "picture" might help
Explanation:
1st pot: 2 flowers
2nd pot: 2 flowers
3rd pot: 2 flowers
4th pot: 2 flowers
5th pot: 2 flowers
6th pot: 2 flowers
7th pot: 2 flowers
8th pot:2 flowers
If we count these up, we get 16 flowers,
Mark said 8*8=64
Emma said 2*8=16
So, emma is correct
