Divide both sides by 2 2(x+2)=-
move constant to the right x+2=-2
calculate x=-2-2
x=-4
21. In a parallelogram, opposite angles are equal and adjacent angles are supplementary (add to 180°).
m∠R = m∠P = 180° -m∠Q
m∠Q = 107°
m∠P = 73°
25. If you draw any diagonal, it divides the figure into two congruent triangles (by the SSS postulate). Corresponding angles are congruent, so the diagonal is a transversal between parallel lines. Thus opposite sides are parallel and the figure is a parallelogram.
27. Opposite sides are equal, and the diagonals bisect each other. Your four equations are
2w+4 = 5w-6 . . . . w = 10/3
12 = 3x-3 . . . . . . . x = 5
6y = 4y+6 . . . . . . . y = 3
27 = (5/4)z +2 . . . z = 20
Answer:
4/21
Step-by-step explanation:
4/21 can't be reduced anymore there is no number that goes into 4 and 21 and divides perfectly.
4/21 = 4/21
42/54 = 21/27 = 7/9
18/27 = 6/9 = 2/3
2/10 = 1/5
You should be able to find the maximum value of c by simply substituting the maximum values for x and y.
So we'll let x = -2 and y = 6.
The equation is is now as follows:
c = 5(-2) + 4(6)
c = -10 + 24
c = 14
Therefore the maximum value for c is 14.
