80 has 9 factor because 1×80=80. 2×40-80. 4×20=80. 5×16=80. 8×10=80 . 10 ×8=80. 20×4=80. 40×2=80. and 80×1=80 80 is greater than 20 and that has 9 factors
The solution of the system of equations contains one point
<h3>How to determine the number of solutions?</h3>
The system is given as:
x + y = 6
x - y = 0
Add both equations
2x = 6
Divide by 2
x = 3
Substitute x = 3 in x - y = 0
3 - y = 0
Solve for y
y = 3
So, we have x =3 and y = 3
Hence, the solution of the system of equations contains one point

Step-by-step explanation:
Answer:
Wetlands prevent flooding by temporarily storing and slowly releasing stormwater.
Step-by-step explanation:
Wetlands also reduce water flow, thus allowing sediments and associated pollutants to settle out. A marshland can prevent flooding in a nearby town bye temporarily storing water!
Answer:
45.5
Step-by-step explanation:
Angles B and C are equal because it is an isosceles triangle.
This means that 180 = (2x+4) + 2(3x+5)
Then just solve for x
180 = 2x+4+6x+10
180 = 8x+14
166 = 8x
x = 20.75
Now plug this into a
A = 2(20.75)+4
A = 45.5
You can check this buy plugging it into B
3(20.75)+5
B = 67.25
C = B, so C = 67.25
B + C + A = 180
67.25 + 67.25 + 45.5 = 180
134.5+45.5 = 180
180 = 180
