2x + 3y = 45
x + y = 10......y = 10 - x
2x + 3(10 - x) = 45
2x + 30 - 3x = 45
-x + 30 = 45
-x = 45 - 30
-x = 15
x = -15 <====
and y = 25
Answer:
The answer is 5 x 2 x 3 x 2 x 2
Step-by-step explanation:
It is just everything at the bottom multiplied together
Answer:
11
Step-by-step explanation:
Those are alternate exterior angles. IF the lines A and B are parallel, then those angles are equal. Set them equal to each other and solve for x:
5x + 9 = 6x - 2
Combine like terms:
11 = x
A) rhombus
b) trapezoid
c) square
d) rectangle
e) parallelogram
f) trapezoid
g) a parallelogram has 4 sides. The two opposite sides are always parallel.
A trapezoid has 4 sides. Only two opposite sides are parallel. The other two sides are not parallel.
h) a square has angles that must be 90degree big. A rhombus doesn’t.
