Ihave 28 red and blue marbles. the ratio of red to blue is 1: 6. how many blue marbles do i have

You have 24 blue marbles.

Step-by-step explanation:

We can solve this question by a system of equations.

I am going to say that:

x is the number of red marbles.

y is the number of blue marbles.

28 red and blue marbles

This means that

The ratio of red to blue is 1:6.

This means that for each red marble(x), we have 6 blue marbles(y). So

y = 6x.

Then

We want the number of blue marbles(y)

You have 24 blue marbles.

so a parallelogram is just like a square base times height. multiply 40 and 39 to get 1560 inches.

a triangle is base times height divided by two. so multiply 7.9 and 5 and then divide it by 2 to get 19.75inches.

the kite can be split into two separate triangles and added together to get the total area. 30 x 4 /2 which equals 60. make sure to double it for the two triangles making 120.
