Answer:

Number of blue marbles = 86.

Step-by-step explanation:

Let number of blue marbles = x, then the number of red marbles = 106-x.

From the second relation given in the question:-

x =  4(106 - x) + 6

Solving for x:-

x = 424 - 4x + 6

5x = 430

x = 86 blue marbles.

The perimeter of a triangle is 53 feet. One side of the triangle is 12 feet shorter than the second side. The third side is is 4
grandymaker [24]

Let the shortest side be = a, then side b = 2·a and side c = (b + 24)

We are given that a + b + c = 84

Substituting for b and c

a + 2·a + (a + 24) = 84

4·a + 24 = 84

4·a = 84 - 24 = 60

a = 60/4 = 15 feet

b = 2·15 = 30 feet

c = 15 + 24 = 39 feet


sorry if i am wrong
