The blueprint for the pelham's living room has a width of 12 inches using the scale of 2 inches = 7 feet. The family wants to use a scale of 1 inch = 6 feet. What is the width of the living room on the new blueprint?

Arianna is buying plants for her garden. she buys 15 flowering plants for $96. pink flowering plants sell for $8, and purple flowering plants sell for $5. how many pink flowering plants did arianna buy? i figured out the answer! the answer is 7. 8x +5y = 96 plug in 7 for x 8 (7) + 5y = 96 56 + 5y = 96 subtract 56 from both sides 5y/y = 40/5 y = 8 she bought 7 pink and 8 purple plants

I'm confused on this could anyone me and show me what i need to do to solve it.
