Answer:
B
Step-by-step explanation:
Since the inequality is < then the line separating the shaded and plain regions will be broken.
Thus graph A or B
Choose a test point in each shaded region and check validity of solution
From A choose (0, 2), then
2 < 0 + → 2 < ← False
From B choose (0, - 2), then
- 2 < 0 + → - 2 < ← True
Thus the graph representing the inequality is B
Answer: it will take 23 weeks for both of them to weigh the same.
Step-by-step explanation:
Let x represent the number of weeks that it will take both of them to weigh the same.
Let y represent the weight of Jose in x weeks.
Let z represent the weight of Marty in x weeks.
Jose weighs 180 pounds and plans on gaining 2 pounds per week. This means that
y = 180 + 2x - - - - - - - - 1
Marty weighs 249 pounds and plans on losing 1 pound per week. This means that
z = 249 - x - - - - - - - - 2
To determine the number of weeks that it will take both of them to weigh the same, we will equate both equations. It becomes
180 + 2x = 249 - x
2x + x = 249 - 180
3x = 69
x = 69/3 = 23
The length of one edge of the triangular pyramid is 6 cm
<h3>How to determine the length L?</h3>
The area is given as:
Area = 240 square centimeters
The net of the triangular pyramid consists of:
- 4 triangles
- Each triangle has the same base (L) and height (10)
So, the area of the net is:
Area = 4 * Base * Height
This gives
240 = 4 * L * 10
Divide both sides by 40
L = 6
Hence, the length of one edge of the triangular pyramid is 6 cm

Answer:
400$
Step-by-step explanation:
Let C.P. of the watch = Rs. 100
When profit =5%; S.P. = Rs. (100+5)
= Rs. 105
and when profit = 11%;
S.P. = Rs. (100+11)
=Rs.111
Difference of two selling prices
= Rs. 111-Rs.105 = Rs.6
When watch sold for Rs. 6 more; then C.P. of the watch = Rs.
