The answer is nine, because the ratios need to stay equal. 9+3=12, 6+3=9
Answer:
10 games
Step-by-step explanation:
Let C be cost and x be number of games
Arcade A: C = 5 + 0.6x
Arcade B: C = 7 + 0.4x
for both arcades to be the same price, Both C's must be equal, hence we equate the right side of both equations:
5 + 0.6x = 7 + 0.4x (subtract 5 fromboth sides)
0.6x = 7 + 0.4x - 5
0.6x = 2 + 0.4x (subtract 0.4x from both sides)
0.6x - 0.4x = 2
0.2x = 2 (divide both sides by 0.2)
x = 2 / (0.2)
x = 10
Answer:
92
Step-by-step explanation:
The parallelogram is divided into two triangles. Remember, angles in a triangle add up to 180 degrees. That being said, take the sum of the numbers given in triangle ABC and subtract it from 180.
60 + 28 = 88
180 - 88 = 92 (this is the measure of angle B)
Angles D and B are congruent, which means they are the same.
Since Angle B is 92 degrees, then D is 92 degrees also.
