First lets write this out:-
?
19 - 10 = 20 - 10
Now lets solve:-
19 - 10 =9
?
9 = 20 - 10
20 - 10 = 10
9 ≠ 10
Since 9 does not equal 10:-
19 - 10 ≠ 20 - 10

Answer:
a) 4.33 (three repeating)
b) 3.5
c) 3
d) 0.44
Step-by-step explanation: Mean is all the numbers added up and divided by the amount of items. All the items added together are 78. We have 18 items 78/18 = 4.3 (three repeating). Median is just the middle value. This is between 3 and 4 so 3.5. Mode is the one that shows the most. This is 3. 8 students play games for more than 4 hours. 8/18 = 0.44
Let's call the younger student's age A and the older student's age B. The teacher's age will be T.
B = 2A
T = 5B
T+5 = 5(A+5)
Simplify the last equation.
T+5 = 5A+25
T = 5A+20
Now we have two equations solved for T, so we can set them equal to each other.
5B = 5A + 20
We can plug 2A in for B
5(2A) = 5A + 20
10A = 5A + 20
5A = 20
A = 4
To find T, we plug 4 in for A in T = 5A + 20
T = 5(4) + 20
T = 40
The answer is 40 years old.
The ratio of boys to girls in simplest form is
14:16
14/16
Divide through by 2
7/8
So the ratio of boys to girls in simplest form is 7/8
