The inequality would be
0.75q ≥ 0.70(q+1)
q is defined as the number of questions he answers after the first one. We are told he gets 75% of those correct; 75%=75/100=0.75. This gives us 0.75q.
Since he gains proficiency on the exercises, the total number he gets correct has to be at least 70%. This means the inequality would have the symbol greater than or equal to, as it cannot be less and have him gain proficiency.
He has already answered 1 question and answers q more; this gives us a total of q+1. Since he gains proficiency, the cutoff was 70%; 70%=70/100=0.70. This gives us the expression 0.70(q+1).
Our total inequality would then be 0.75q ≥ 0.70(q+1)
I thought that to till on saturday my friend was doing school i was with him he had to do some math algebra 2b he needs it to be a mechanical engineer
Answer:
79
Step-by-step explanation:
see which ones are vertical to each other and since they are vertical to each other they are the same degree then and all of the numbers you already have and the answer from that subtract it from 360 and them divide it by 2 .
64+64=128
37+37=74
128+74=202
360-202=158
158÷2=79
Simplifies the problem, you divide by a value which if plugged into x would equal 0. One example is dividing by (x-1) as x=1 results in 0
