The isosceles triangle has a perimeter of 7.5 m. which equation can be used to find the value of x if the shortest side, y , measures 2.1 m?

The value of x is 2.7 m.

Step-by-step explanation:

An isosceles triangle has two equal sides.

1) Write the equation based on the provided context

2.1 m + 2x = 7.5 m

2) Take away 2.1 m from each side of the equation

(2.1 m + 2 x) - 2.1 m = 7.5 m - 2.1 m

2x = 5.4 m

3) Isolate the variable x to find the x value.

x= 5.4 m/ 2

x= 2.7 m

there are 70 more legs than eyes at the dog show (196 – 126 = 70). dogs have two more legs than eyes, and humans have the same number of legs as eyes. thus 70 is twice the number of dogs at the show, so the number of dogs is half of 70, which is 35. to get the number of humans, subtract 35 from 63: 63 – 35 = 28.
