We can set Maggie's age to x
If her brother is six years younger than four times her age, than her brother must be equal to: 4x-6
Since the sum of their ages is 39, we can set up an equation.
(Sum of Maggie's age) + (sum of Maggie's brother's age) = 39
x + (4x -6) = 39
5x -6 = 39
5x = 45
x = 9 , Maggie's age is 9
Answer: (-3,5)
Step-by-step explanation:
(-2,-3) would not work because adding them together would sum -5 which is less than 5 but y is not greater than -2.
(0,4) would not work because 4 isn’t greater than 4.
(-3,5) would work because -3+5=2 which is less than 4.In addition, 5 (the y value) is greater than -2.
(1,4) is incorrect because 1+4=5 which is greater than 4.
In other words,
5>-2
-3+5 < 4
Given:
Total number of girls in her class = 16
Total number of boys in her class = 14
To find:
The number of different ways of choosing one girl and one boy.
Solution:
We have,
Total number of girls = 16
Total number of boys = 14
So,
Total number of ways to select one girl from 16 girls = 16
Total number of ways to select one boy from 14 boys = 14
Now, number of different ways of choosing one girl and one boy is
Therefore, the required number of different ways is 224.
Answer:
Either through decimals or finding common denominators.
Step-by-step explanation:
When you get decimals you can clearly see which is bigger and with common denominators, you can just cancel out the denominator and see which is bigger. If you'd like me to provide an example just let me know :)
