Benjamin’s and David’s ages add up to 36 years. The sum of twice their respective ages also add up to 72 years. Find their ages
nydimaria [60]
Answer:Benjamin’s age = 30 and David’s age = 6

Explanation:

Let x be the age of Benjamin
Let y be the age of David

x + y = 36

And 2x + 2y = 72

If we plug 30 for x and 6 for y we get:

30 + 6 = 36
36 = 36

2(30) + 2(6) = 72
60 + 12 = 72
72 = 72

The shortest side of an idosceles triangle is 2x+5 inches. The 2 longest sixes are 3 inches longer. The perimeter of the triangl
Rzqust [24]

Answer:

Step-by-step explanation:

In an isosceles triangle, two sides and two angles are equal.

The shortest side of an isosceles triangle is 2x+5 inches. The 2 longest sides are 3 inches longer. This means that the length of each of the longer sides is

2x + 5 + 3 = 2x + 8 inches

The formula for determining the perimeter of a triangle is expressed as

Perimeter = a + b + c

Where a, b and c are the sides of the triangle.

The perimeter of the triangle is 21 inches. Therefore, the equation that can be used to find the length of each side of the triangle is

2x + 5 + 2x + 8 + 2x + 8 = 21

6x + 21 = 21
