Write and solve a system of equations that represents the given situation.
A. 25 weeks
B. 20 weeks

Answers
Answer:
B. 20 weeks
Step-by-step explanation:
I am using the graphing calculator my school uses for exams. But here is the step by step anyway
5x + 36 = 2x + 96
(5x - 2x) + 36 = (2x - 2x) + 96
3x + 36 = 96
3x + (36 - 36) = (96 - 36)
3x = 60
(3x ÷ 3) = (60 ÷ 3)
x = 20
x represents weeks

The numbers in the series is
2 - 5 - 7 - 14 - 41 - 122 - 365 - 1094 - 3281
First number is 2
[tex]2 \cdot 3 -1=5\\[/tex]
Lets multiply the previous term by 3 and subtract 1 to check the other terms
[tex]5 \cdot 3 -1= 14\\14 \cdot 3 -1= 41\\41 \cdot 3 -1= 122\\122 \cdot 3 -1= 365\\365 \cdot 3 -1= 1094\\1094 \cdot 3 -1= 3281\\[/tex]
From the series we can see that 7 does not belong to the series .
So, SEVEN does not belong to the series .

Find the area of the shaded region.
help pls
Answers
Answer:
1. 50 m
2. 80 cm
Step-by-step explanation:
1. There are 2 triangles, subtract the area of 1 of them from the other.
The triangle that needs to be subtracted: b = 20 m, h = 10 m
A = 1/2b * h = 1/2(20) * 10 = 10*10 = 100 m
The big triangle, the one that needs to be subtracted plus the one you need to find the area of: b = 20 cm, h = 15 cm, 1/2(20) * 15 = 10 * 15 = 150
150 - 100 = 50 c
2. Divide it into 3 parts:
1- 3*4 = 12
2. 7*(4 + 4) = 7*8 = 56
3. [(4 + 4) * (13 - 7 - 3)]/2 = (8*3)/2 = 24/2 = 12
12 + 56 + 12 = 80 cm

Add all the sides for perimeter

Answer:
281 m squared
Step-by-step explanation:
What we can first do is find the top length so we can do
17+3+3=23
then we can multiply it by the side length to get the whole rectangle
23*13=299
and we know each of the little areas is 9, and there are two so
9+9=18
and we can subtract that from the whole rectangle
299-18=281

This is because to find out how many grapefruits they sold, you would first need to find the two numbers to you can multiple 10 and 1 by so they would add up to 307 and 100. The numbers that work are 23 and 77. So, when you multiply 10 to 23 (10 because it’s the cost of nuts), you would get the answer of 230. Then you would subtract 307 by 230 because 307 is the total amount of money they earned from selling. When you do that, you would get 77. After that, you multiply 1 times 77 because the cost of the grapefruit is $1. When you add 23 and 77, you should get 100. The total items they sold. When you add 230 and 77, youd get 307. So, there were 77 grapefruits that they sold.

Answers
Answer:
Part A: 56
Part B: 43.9
Part C: I think the medain is more apropriate in this situation because it takes out the outlier , 3, that is affecting the mean
Step-by-step explanation:
Part A: To calculate the median you must have all of the numbers in numerical order so, 3,31,37,56,57,61,62, The medain is the number in the middle or closet to the middle. In this case 56 is directly in the middle so 56 is your median.
Part B: To find the mean you must add all of the values together and then divide by the number of values you have so when you add 3+31+37+56+57+61+62 it equals 307 and you divide it by 7 because there are 7 numbers in this data set and you get 43.9 when you round to the nearest tenth.
Part C: explanation in answer.
