An equilateral triangle has a perimeter of 72 inches. One side measures 10 + 7h inches. Let h = height of the triangle.
a) Write an equation and solve to determine the length of one side. What is the length of one side?
b) What is the area of the triangle if A = 1/2 base * height? Show your work.

step-by-step explanation:

.6 is 1/2 of 12

the answer is actually d. i just took the test

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

i would be happy to . most people on would also love to i'm sure. if you just want someone who has done algebra before and want a little more personal relationship than just begging strangers for , i can certainly be of service. i do have college myself so i might not be 24/7.
