y= 100-2x where y= total score (0 through 100) and x= # of questions wrong (0 through 50)
Step-by-step explanation:
100- 2(8) = y
100-16 = y
84=y
Since each question (x) is worth two points (2) we have to multiply each wrong question by two (2x). And then since we're deducting point from the possible points (100) we have to subtract (100-2x)
Given that ∠CEA is a right angle which has been bisected by BE, then: ∠CEB=∠BEA thus each angle will be complementary to each other, hence the size will be: 90/2=45° hence the correct statement. <span>m∠CEB = 45°</span>
