Answer:
1) 62.5%
2) 8-x/8=y/100 (where y is the percent)
Step-by-step explanation:
1) so there’s 8 questions in total cause each question si 5 points and 40 points is the max so 40/5=8
write a proportion where 8-3/8=y/100 (it’s 8-3 because it’s total question minus the wrong questions and you’ll get the remaining points and put it over a hundred since the max score you can get is a hundred.
so 5/8= y/100
cross multiply
500=8y
Divide 8 on both sides
you’ll get 62.5
2) Jist use the equation 8-x/8=y/100
( where x is the wrong amount of questions and y is the total percent)
Answer:
1
Step-by-step explanation:
First, we need to find the solution to the system of equations. If x+1 = 2x + 1 , solving for x we have that: x=0.
Given that x=0, the possible value of x+1 = 0 +1 = 1.
