Fifteen toothpicks are used to make three hexagons. Find the minimum number of extra toothpicks required to extend the pattern to seven hexagon. Please explain step by step or show work to get marked =]

x + y = 90 5x – 10y = 90 90 – 10y = 5x 90 + 10y = 5x

step-by-step explanation:

last month maria hiked the 5-mile mountain trail a number of times and she hiked the 10-mile canal trail several times. let x represent the number of times she hiked the 5-mile trail, and let y represent the number of times she hiked the 10-mile trail. if she hiked a total of 90 miles, which equation can be used to find the number of times maria hiked each trail? x + y = 90 5x – 10y = 90 90 – 10y = 5x 90 + 10y = 5x

hi,

the area of abcd is 245.

3*24=230

4*94=1039
