Let all attempted passes = x
70% of x = 350
(70/100)*x = 350
7x/10 = 350
7x = 350 * 10
x = (350 * 10) /7
x = 500
John attempted 500 passes.
Answer:
£12
Step-by-step explanation:
Mathematically, we know that the mean is calculated by dividing the sum of the numbers by the count of the numbers.
Now, when they were 6 and the mean is £5, this means that the total is simply
6 * 5 = £30
Now, when a new student join, there is an increase in the value of the mean.
A new student joining means they are now 7 with the total now 7 * £6 = £42
Now the difference between the total of 6 and 7 will be £42 - £30 = £12
This value represents what the new pupil receive each week
Pretend the equation was 2x - 4 > 8
The first step (of the two) would be to add 4 to the (-4) and to the other side of the equation (+4) to the 8, first. (You wouldn't use the number with variable in the first step) Then you would rewrite the equation: 2x > 12 (it's now 12 because you added the 4 to the 8). The second step is to divide 2x by 2x and do the same with 12. By dividing both sides with the coefficient, will help find "x". 12/2 is 6, therefore x > 6. (the last step would be to graph the expression if needed to)
Answer:
2.5
