let the sides of triangles be a, b, & c ; where c is the shortest side, a is the longest side and b is the middle side .
given perimeter of triangle = 34 inches
i.e. a + b + c = 34
given middle side is twice long as shortest side i.e. b = 2 x c = 2c .......(1)
given longest side is 2 inches less than three times shortest side
i.e. a = 3x c - 2 = 3c -2 .......... (2)
substituting (1) & (2) in equation a + b + c = 34
we get, 3c-2 + 2c + c = 34
3c+ 2c+ c -2 =34
6c -2 = 34
6c = 34 + 2 = 36
c = 36/ 6 = 6
a= 3c - 2
= (3 x 6) - 2
= 18- 2 = 16.
b = 2c = 2 x 6 = 12
so three sides of the triangle are 16 inches, 12 inches & 6 inches
Answer:
B
Step-by-step explanation:
You have to add 7 to both sides to isolate the variable
All you have to do is put 14 over 120 and divide. So 14/120 will become 0.11666666666 in decimal form. To round to the nearest thousandth, just count 3 places from the decimal point and look at the number to the right. If it is higher than 5, add one the 3rd number from the decimal, but if it is not, then just keep it the same. So, in this case it would be 0.117
