Answer:
x=1
Step-by-step explanation:
1) 6x-5y=5
2) 3x+5y=4
ets perform the following operation
1) +2), This leads to the following equation:
6x+3x-5y+5y=5+4
From where we obtain the solution for x
9x=9
x=1
Simplification = 3.5x + 2.5x
Result = 6x
Answer:
Isosceles trapezoid
Step-by-step explanation:
-An isosceles trapezoid is also sometimes called a convex quadrilateral.
-It properties include:
- A line of symmetry can often bisects a pair of opposite sides.
- It has to obtuse alternating with each other after which a pair of acute angles alternate with each other i.e 80°, 80°,100°,100°
- It has a trapezoidal shape which by definition has a two pair of parallel sides.
- The angles on it's base or ceiling are equal hence the name Isosceles Trapezoid.
Volume = 4/3×pi×r^3
= 4/3×3.14×12^3
= 7234.56
~ 7235
The answer is -65, -13, -7.6, 7.6, 34, 55, 62.5
Although the negative numbers may seem larger than the positive numbers that is not the case since negative numbers are below zero.
Such as this is the case of transition from negative to positive
-5,-4,-3,-2,-1, 0,1,2,3,4,5
