Answer:
see below
Step-by-step explanation: 5 20 15 28
3x + y = 23
3x – 2y = 8
O I should add, and the Xs will be eliminated. 3x + 3x = 6x NOT eliminated
O I should add, and the Ys will be eliminated. y + -2y = -y NOT eliminated
O I should subtract, and the Xs will be eliminated. 3x - 3x = 0x X is eliminated
O I should subtract, and the Ys will be eliminated. y - -2y = y NOT eliminated
That system has D. no solutions
Two angles in the same parallelogram must either be equal or else add up to 180 degrees. These two are obviously not equal, so they must add up to 180.
A + B = 180
A = 180 - B (we'll use this in just a second)
A = 3B + 40
180 - B = 3B + 40
Add 'B' to each side:
180 = 4B + 40
Subtract 40 from each side:
140 = 4B
Divide each side by 4 :
<u>35 = B</u>
A = 180 - B = <u>145</u>
