Ms. Boyd has 9 bills in her purse that consist
of five-dollar bills and twenty-dollar bills. The
value of the bills is worth $105. How many
five-dollars bills and twenty-dollar bills does
Ms. Boyd have?
Answer:
number of $20 bill = 4
Number of $5 bill = 5
Step-by-step explanation:
Given that:
Total number of $5 and $20 bills = 9
Let :
Number of $5 bills = x
Number of $20 bills = y
Combined worth of all bills = $105
x + y = 9 - - - (1)
5x + 20y = 105 - - - (2)
From (1)
x = 9 - y
Substitute x = 9 - y into (2)
5(9 - y) + 20y = 105
45 - 5y + 20y = 105
15y = 105 - 45
15y = 60
y = 60/15
y = 4
x = 9 - y
x = 9 - 4 = 5
Hence,
number of $20 bill = 4
Number of $5 bill = 5
Given the exponential function f(x) = 16(0.75)x, classify the function as exponential growth or decay and determine the percent rate of growth or decay.
Exponential growth, 75% increase
Exponential decay, 75% decrease
Exponential growth, 25% increase
Exponential decay, 25% decrease
Answer:
So the rate of decay is 0.25, or 25%.
Step-by-step explanation:
The variable r gives the rate of decay in the formula f(x) = P(1 − r)x = 16(1 − 0.25)x.
Answer:
Exponential decay, 75% decrease

Isadora rents an apartment for $1,000 a month and has a year's lease.
She owns a car that is worth $14,700. She has a savings account of $4,750 and a
credit card balance of $825. What is her net worth?
Step-by-step explanation:
So let's say this is for the year and were working out the amount she spent.
She starts off with paying $1,000 for rent.
Then she owns a car that is $14,700.
Her savings account is 4,750 and Credit card balance is 825{not sure if that's what she is has to spend or if its tax so I'll do two ways}.
1,000
4,750
825
+14,700
21325
Her total would be $21,325 taking it that 875 was a tax.
if not the answer would be $20,450.
if the car does not have a tax just minus the 14,700 from either of them two numbers.
Amount of Isadora's net worth is $6,625.
What is an expression?An expression contains one or more terms with addition, subtraction, multiplication, and division.
We always combine the like terms in an expression when we simplify.
We also keep all the like terms on one side of the expression if we are dealing with two sides of an expression.
Example:
1 + 3x + 4y = 7 is an expression.
3 + 4 is an expression.
2 x 4 + 6 x 7 – 9 is an expression.
33 + 77 – 88 is an expression.
We have,
To find Isadora's net worth, we need to subtract her total debts from her total assets.
So,
Her total assets.
Car worth = $14,700
Savings account balance = $4,750
So, her total assets.
= $14,700 + $4,750
= $19,450
Her total debts.
Credit card balance = $825
Monthly rent for 1-year lease = $1,000 x 12 = $12,000
So, her total debts.
= $825 + $12,000
= $12,825
To find her net worth, we subtract her total debts from her total assets.
So,
Net worth = Total assets - Total debts
Net worth = $19,450 - $12,825
Net worth = $6,625
Therefore,
Isadora's net worth is $6,625.

En una escuela se recibieron plumas de diferentes patrocinadores. Por parte de la sociedad de padres compraron 4 1⁄4 cajas. La Sociedad de Alumnos aporto 2 5/6 cajas. Y 3 3⁄4 cajas regalo Un Programa de Educación ¿Cuántas cajas de plumas son en total?
Answer:
[tex]10\frac {5}{6}[/tex] boxes
Step-by-step explanation:
Given that pens received from the parents' society [tex]= 4 \frac 1 4[/tex] boxes.
Pens received from the Student Society [tex]= 2 \frac 56[/tex] boxes.
Pens received as gift boxes [tex]= 3 \frac 3 4[/tex] boxes.
So, the total number of boxes of pens received [tex]= 4 \frac 1 4 + 2 \frac 56 + 3 \frac 3 4[/tex] boxes
[tex]=\frac {17}{4} + \frac {17}{6} +\frac{15}{4}\\\\=\frac {65}{6}\\\\=10\frac {5}{6}.[/tex]
Hence, the total number of boxes of pens received [tex]= 10\frac {5}{6}[/tex] boxes.
On Thursday the basketball coach ordered 12 pizzas for 36 players who came in for practice. How many pizzas does the coach need to order if 12 players turned up for practice the next day
Answer:16
Step-by-step explanation:Next day there will be (36+12) or 48 players.
For 36 players 12 pizzas are needed
For 1 player 12/36 pizzas are needed
For 48 players 12/36*48 or 16 pizzas are needed
The number of pizzas that 12 players will need is 4 based on the given ratio.
What are the ratio and proportion?The ratio is the division of the two numbers.
Proportion is the relation of a variable with another. It could be direct or inverse.
As per the given,
The ratio of pizza to players = 36/12
With the same ratio,
The number of pizzas required for x number of 12 players,
12/x = 36/12
x = 144/36 = 4
Hence "Based on the above ratio, 12 players will require 4 pizzas.".

The system of equation are
5x+ 2y = 3.457x+ 3y= 4.90what is Algebra?A branch of mathematics known as algebra deals with symbols and the mathematical operations performed on them. Variables are the name given to these symbols because they lack set values. We frequently observe constant change in specific values in our day-to-day situations. But the need to depict these shifting values is ongoing. These values are frequently represented in algebra by symbols such as x, y, z, p, or q, and these symbols are known as variables. In order to determine the values, these symbols are also subjected to various addition, subtraction, multiplication, and division arithmetic operations.

Olivia has 28 video discs, which is less than 4 times the number of video discs in Michelle collection. How many videos does Michelle own?
Complete Question:
Olivia has 28 video discs, which is 8 less than 4 times the number of video discs in M collection. How many videos does M own?
Answer:
9 video discs
Step-by-step explanation:
Let M video collection = x
Given the following data;
O video disc = 28
Translating the word problem into an algebraic equation, we have;
28 = 4x - 8
28 + 8 = 4x
36 = 4x
x = 36/4
x = 9 discs
Therefore, M owns 9 video discs.
Stephanie grew a total of 70 pounds of tomatoes to sell. She plans to sell the tomatoes for $3.50 per pound. The equation below represents the profit in dollars, f(x), she will earn by selling x pounds of the tomatoes.
f(x) = 3.50x - 110
If Stephanie sold all 70 pounds of tomatoes, what would her profit be?
Answer:
If Stephanie sold the 70 pounds of tomatoes, her profit would be 135 dollars.
Step-by-step explanation:
You know that the equation f(x) = 3.50*x - 110 represents the profit in dollars Stephanie will earn by selling x pounds of the tomatoes.
If Stephanie sold the 70 pounds of tomatoes, you want to know what the profit would be. So to calculate the profit you simply replace in f (x), the x pounds of tomatoes by 70.
f(70)=3.50*70 - 110
Solving:
f(70)= 245 - 110
f(70)= 135
If Stephanie sold the 70 pounds of tomatoes, her profit would be 135 dollars.
