Combine like terms

36=3n

Divide 3 from both sides

12=n

the lengths of the four sides as a quadrilateral (in feet) are consecutive integers if the perimeter is 86 ft find the value of
tia_tia [17]

Let x be the shortest side

Let x+1 be the second side

Let x+2 be the third side

Let x+3 be the fourth and longest side

perimeter = s_{1} + s_{2} + s_{3}  + s_{4} \\ 86 = x + (x + 1) + (x + 2) + (x + 3) \\ 86 = x + x + 1 + x + 2 + x + 3 \\ 86 = 4x + 6 \\ 4x = 80 \\ x = 20

Shortest side is 20 cm

Longest side is x+3 so 20+3=23

Answer:

Identifying and Writing Equivalent Rates

Ratios compare two quantities. A rate is a type of ratio that compares two quantities that have different units of measurement. The word “per” is often used to describe rates.

Rates can be written as fractions. The first quantity is the numerator and the second quantity is the denominator. Different rates that have the same value are equivalent rates. You can find an equivalent rate the same way you find equivalent ratios—divide or multiply the numerator and the denominator by the same number.
