Answer:
14 miles
Step-by-step explanation:
2.80+1.20x=20
-2.80 -2.80
1.20x=17.20
1.20x/1.20= 17.20/1.20
x=14 miles
Hope this helps!
First, you should try to find the sum of the two legs. Because the triangle is isosceles so the legs (b) are equal, than the sum of the two legs:
41*2 ≤ 2b ≤ 43*2 simplified is: 82 ≤ 2b ≤ 86
But we aren't done, for the perimeter also includes the base of the triangle, which is a. Since we already know the sum of the legs, we simply have to add the base (a) to the legs.
Sum of Legs: 82 ≤ 2b ≤ 86
Base: 26 ≤ a ≤ 28
Perimeter (a+2b): 82+26 ≤ P ≤ 86+28 Which simplified: 108 ≤ P ≤ 114
Answer:
x means 2 and y means -2

You just take the number and for each whole number, that's 100 % if there is decimals, you take while percent . tens. hundreads....
