Answer: -18, -20, -22
Step-by-step explanation:
The integers are obviously approximately equal to -20, since they cover only 5 numbers, and there are three of them and their sum is -60. So guess -18, -20, -22. That works.
Answer:
Therefore a triangle can be formed with side lengths of 4 m, 8 m, 9 m
Step-by-step explanation:
A triangle is a polygon with three sides and three angles. There are different types of triangles such as scalene, isosceles, equilateral and so on.
The triangle inequality property states that the sum of any two sides of a triangle must be greater than the third side. If a, b and c are the sides of a triangle then:
a + b > c; a + c > b; b + c > a
Given a triangle with side length 4 m, 8 m, 9 m:
4m + 8m = 12m > 9m
4m + 9m = 13m > 8m
8m + 9m = 17m > 4m
Therefore a triangle can be formed with side lengths of 4 m, 8 m, 9 m.
Volume of a cylinder = π (radius)² (H)
Radius = 1/2 of the diameter = 1 inch
Volume = π (1)² (6) = 6 π = <u>18.8 cubic inches</u> (rounded)
But have you ever seen a soda can that's only 2 inches in diameter ? ?
You would need to isolate the "X" variable because it is common in all 3 equations.
Answer:
The number is -1/2
Step-by-step explanation:
Let x be the number
2x+8 = 7
Subtract 8 from each side
2x+8-8 = 7-8
2x = -1
Divide each side by 2
2x/2 =-1/2
x = -1/2
The number is -1/2
