Answer:
30
Step-by-step explanation:
Him plus his friend equals 5 and 150/3 is 30
So 150 divided by 5 is 30
0.377 + 5.51 = 5.887
Sorry I can only solve the first one. Could you give me a hint on how to do the second one ?
Answer
(3,1)
Explanation
(6,2) is the same as (3,1) because the x value and y value are proportional, meaning you multiplied or divided both the x value and y value by the same number.
6 divided by 2 is 3.
2 divided by 2 is 1.
(1,3) doesn't work because the x value and y value are switched.
6 divided by 6 is 1.
2 divided by 6 is not 3.
(8,12) doesn't work because the x value and y value are switched... and it wouldn't work anyways.
6 divided by 3/4 is 8.
2 divided by 3/4 is not 2.
(12,8) doesn't work because the x value and y value aren't proportional.
12 divided by 2 is 6.
8 divided by 2 is not 6.
Therefore only (3,1) could be another ratio to (6,2).
(9x - 5y)(2x + 3y)
9x(2x + 3y) - 5y(2x+ 3y)
9x(2x) + 9x(3y) - 5y(2x) - 5y(3y)
18x² + 27xy - 10xy - 15y²
18x² + 17xy - 15y²
