1. Ned has a budget of $1200 for the allowance of his three kids. How much will Robb, Brandon, and Rickon get if the money was divided with a ratio of 3:4:5?Solution:
3x+4x+5x=1200 3(100)= $300 for Robb
12x=1200 4(100)= $400 for Brandon
X=100 5(100)= $500 for Rickon
2. The ratio of two complementary angles is 5:4, find the larger angle.Remember that the sum of complementary angles is equal to 90°
thus,5x+4x=90 5(10)= 50°9x=90
The larger angle is equal to 50°x=10
