Answer:
No. of gonjas = 52
No. of more nzemas than fantes = 78
Step-by-step explanation:
Total no. of people = 520
No. of fantes = 
× 520
No. of fantes = 156
No. of ewes = 
× 520 = 130
No. of nzemas = 
× 520 = 78
No. of gas = 
× 520 = 104
No. of gonjas = 520 - (156 + 130 + 78 + 104) = 52
No. of fantes = 156
No. of nzemas = 78
No. of more nzemas than fantes = 156 - 78 = 78
Pie chart of the following problem is shown below.
<span>50-8t<90
50-90<8t
-40<8t
8t>-40
t>-5
Solutions should go to the right.
Mary probably was solving it as following
</span>50-8t<90
<span>-8t<90-50
-8t<40 (here, when she divided both sides by -8, she had to change sign < to the sign >)
But she did not change the sign, and got
t<-5
</span>
Let the number be x.
-(3/4)*x = -(7/8)
x = -(7/8)/-(3/4)
x = 7/8 * 4/3
x = 7/6
The number = 7/6
I Believe the answer is B. 2b²-3
