Answer:
31
Step-by-step explanation:
There is the possibility that many numbers could be put in here. The simplest one is the average of 10 and 52
10 + 52 = 62
62 / 2 = 31
So the series becomes 10 31 52.
Add 21 to get the next term. So 52 + 21 = 73.
Answer:
last option
Step-by-step explanation:because 9x9 is 81 subtract 1 and you get 80 5x5=25-1=24 so that wont work 4x4=16-1=15 so that also wont work and 7x7=49-1=48 so -9 and 9 is the right answere
Given:
Tom's earnings: x
Jan's earnings: 2x - 150
Total earnings: 1380
x + 2x - 150 = 1380
3x = 1380 + 150
3x = 1530
3x/3 = 1530/3
x = 510
Tom's earnings: x = 510
Jan's earnings: 2x - 150 = 2(510) - 150 = 1,020 - 150 = 870
total earnings: 1,380
510 + 870 = 1,380
1,380 = 1,380
Answer:
The Number is 8.
Step-by-step explanation:
Let the number be x.
Given:
1/2 is subtracted from four times the reciprocal of a number, the result is 0.
Hence the equation will become like;

Now Solving the equation we get.

Now the we can see the number is 8, when 1/2 is subtracted from 4 times the reciprocal of number means 4/8 which becomes 1/2 and hence when 1/2 is subtracted from 1/2 it equals to 0.
Hence the number is 8.
