A triangle has a perimeter of 165 cm. The first side is 65 cm less than twice the second side. The third side is 10 cm less than

Dima020 [189]

Answer:

first side: 55 cm
second side: 60 cm
third side: 50 cm

Step-by-step explanation:

The problem statement gives all the side lengths in terms of that of the second side. Let s represent the length of the second side in cm. Then the length of the first side is (2s-65), and the length of the third side is (s-10). The perimeter is the sum of all the side lengths:

165 = (2s -65) +s +(s-10)

165 = 4s-75

240 = 4s

60 = s . . . . . . . . second side

2s-65 = 55 . . . . first side

s-10 = 50 . . . . . . third side

In order, the side lengths are 55 cm, 60 cm, 50 cm.

Dafna1 [17]

Answer:

Step-by-step explanation:

$n,\ n+2-\text{two consecutive even integers}\\\\\text{The equation:}\\\\n+(n+2)=-42\\\\n+n+2=-42\qquad\text{subtract 2 from both sides}\\\\2n=-44\qquad\text{divide both sides by 2}\\\\n=-22\\\\n+2=-22+2=-20$
