If I were to simplify the expression 10-19 would my answer be a positive or a negative an why
Answer:
It would be negative. 10 subtracted by any number higher then 10 will always be negative. Make a number line and go backwards 19 if you need the help.
Step-by-step explanation:
Answer: It will be negative because 19 is greater than 10 and 19 itself is being subtracted from 10.
Step-by-step explanation:
10-19 is equal to -9.
An example is using the number line to plot the solution, you will start from 10 and move backwards 19 units because you are subtracting 19 from 10. If a bigger number is being subtracted from a smaller number, the solution will be always negative.
Bridget goes to the mall and buys a shirt for $15.50, a pair of jeans for $32.00, and a belt for $24.30. She has a coupon and ends up getting $14.36 off her purchase. What percent off was her coupon for?
Answer:
20%
Step-by-step explanation:
Cost of Shirt = $15.50
Cost for a pair of jeans = $32.00
Cost for a belt = $24.30
Total cost = $15.50 + $32.00 + $24.30 = $ 71.8
Given that, coupon discount = $14.36
To find:
The percentage off on the coupon.
Solution:
The percentage off will be calculated on the total cost.
[tex]\text{Percentage\ off} = \dfrac{Coupon\ discount}{Total\ Cost}\times 100\\\Rightarrow \text{Percentage\ off}= \dfrac{14.36}{71.8}\times 100\\\Rightarrow \text{Percentage\ off} = 0.2\times 100\\\Rightarrow \text{Percentage\ off} = \bold{20\%}[/tex]
Therefore, the answer is:
20%

Change the positions of vertices A, B, and C to create a triangle of your choice. Does the relationship between and change when the vertices of ∆ABC are modified? Explain.
10+
Answer:
No, there is no change in the relationship. The slopes of AC and DE continue to be equal, and the length of DE remains half of the length of AC.
Step-by-step explanation:
The answer is from Plato. I hope this helps :)
Answer:
No, the connection has not changed. The slopes of AC and DE are still equal, and the length of DE is still half that of AC.

the number is being reduced by 23 which means x-23 = 44 and x = 44+23 =67
These two images show steps in a proof of the Pythagorean theorem. Which
of the following statements about the proof is false?
A. The triangles in step 1 have the same combined area as the triangles in step 2.
B. The area of the interior square in step two is greater than the combined area of the two interior squares in step 1.
C. The proof shows that a2+ B2=C2
D. If you subtract the sum of the areas of the four triangles from the complete figure in both steps, the remaining areas are equal.
Answer: B, the area of interior square in step 2 is greater than the combined area of the two interior squares in step 1.
Step-by-step explanation: I took the quiz and got it right
The area of the interior square in step 2 is greater than the combined area of the two interior squares in step 1. Then the correct option is B.
What is a Pythagoras theorem?The Pythagoras theorem states that the sum of two squares equals the squared of the longest side.
The Pythagoras theorem formula is given as
H² = P² + B²
These two images show steps in the proof of the Pythagorean theorem.
The area of the interior square in step 2 is greater than the combined area of the two interior squares in step 1.

A diver descended 20 feet in 5 seconds. What is the average rate per second that he traveled? Explain how you can use integer tiles to solve the problem and find the answer.
Answer: Look Below (-v-) it’s the sample response..
Step-by-step explanation: The diver is moving down, so he moved −20 feet. Start with 20 negative tiles and separate them into 5 equal groups. There are 4 negative tiles in each group, so he traveled at a rate of −4 feet per second.

Hi, I am confused on this question:
The sequence 12, 15, 18, 21, 51, 81, ... consists of all positive multiples of 3 that contain at least one digit that is a 1. What is the 50th term of the sequence?
(Source: 2006 National Target #5)
Answer:
321.
Step-by-step explanation:
The next term after 81 is 102 .
Between 102 and 198 inclusive we have (198-102) / 5 + 1 = 96/3 + 1 = 33 terms - these will all have at least one 1 and be divisible by 3.
So 198 = 6 + 33 = 39th term.
After 198 we have 201, 210, 213, 219, 231, 261, 291, 312, 315, 318, 321
The answer is 321..
