The shadow is always on the ground.
A person and a flagpole always stands up straight, like a wall (vertical height)
Underline key words and numbers. Draw a picture for sure.

|____________ |____
flagpole=50 feet person's shadow=4 feet
shadow
Since it is easier to work with one type of measurement, change the person's height to feet only. The person is 5feet, 6inches Note: 12 inches= 1 foot, so 6 inches= 1/2 a feet and 6 inches= .5 feet

Kyra went to the grocery store on Monday and bought 5 apples and 2 oranges for a total of $3.45. On Thursday she bought 7 apples and 3 oranges for a total of $4.90.
Write a system of equations that represents this situation.
Answer:
5(x)+2(y)=3.45
7(x)+3(y)=4.90
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.
Given:
On Monday 5 apples and 2 oranges for a total of $3.45.
On Thursday she bought 7 apples and 3 oranges for a total of $4.90.
let the number of apples sold be x
and, let the oranges sold be y
So, the equation can be
5x+ 2y = 3.45
7x+ 3y= 4.90

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.

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
