Five pointed star + five pointed star = circle + circle + circle + circle + circle triangle + triangle = five pointed star + five pointed star + five pointed star 1 triangle = () circles the price of 4 pens = the price of 6 ballpoint pens the price of 4 ballpoint pens = the price of 8 pencils the price of 1 pen = () the price of lead pens

Five pointed star + five pointed star = circle + circle + circle + circle + circle triangle + triangle = five pointed star + five pointed star + five pointed star 1 triangle = () circles the price of 4 pens = the price of 6 ballpoint pens the price of 4 ballpoint pens = the price of 8 pencils the price of 1 pen = () the price of lead pens

First question: five pointed star + five pointed star = circle + circle + circle + circle + triangle + triangle = five pointed star + five pointed star + five pointed star 2 five pointed stars = 6 circles, namely 1 five pointed star = 3 circles 3 triangles = 4 five pointed stars = 12 circles, so 1 triangle = 4 circles second question: the price of 4 pens = 6 ballpoint pens

Known: (Pentagram + triangle) * 0.5 = 0.7, Pentagram divided by 0.5 = 1.6?

1、（★＋△）×0.5=0.7
2、★＋△=0.7÷0.5=1.4
3、★÷0.5=1.6
★=1.6×0.5=0.8
△=1.4－0.8=0.6

How many golden triangles are there on the five pointed star?
Contains a line between the five corners
It's an isosceles triangle formed by connecting all five points

The first group is a triangle formed by any two adjacent sides of AB, BC, CD, De, AE, with a total of five. The second group is a triangle formed by any one side and the top point directly opposite this side, such as ACD, with a total of five. The third group is a triangle formed by other two vertices in the second group

How many triangles are there in the pentagram?

Each angle has five independent triangles
Each corner and diagonal form two triangles, the number of repetitions is 5, a total of 2 * 5-5 = 5, total: 10 2) if it refers to the number of triangles between the Pentagon and the inscribed pentagram, the answer is
Each side of the Pentagon has 4 independent triangles, 5 * 4 = 20 in total
There are 5 triangles formed by the adjacent sides of the Pentagon, and 10 triangles with five pointed stars in them, a total of 35 triangles

Two squares and two triangles are equal to 18, two squares and four triangles are equal to 32. How many squares and triangles are equal to?

2 triangle = 32-18 = 14
14 △ 2 = 7 = 1 angle
2 blocks = 18-14 = 4
Square = 4 △ 2 = 2

Five stars divided by triangle equals 6, triangle plus circle equals 12, five stars divided by circle equals 3, how many five stars, how many triangles, how many circles
I want the formula to be more than the result. I know. I just want to know how to work it out
How can explain to the child is easy to understand, do not XY has not learned ah!

★÷△=6 △+○=12 ★÷○=3
So the ratio of △ and ﹣ is 1:2
2+1=3
12÷3=4
That is to say, 4
Then zero = 4 × 2 = 8
△=4×1=4
If you find out ○ and △ then ★ is better
★=4×6=24
Answer: ★ = 24; △ = 4; ∧ 0 = 8

Given triangle + circle = 60, triangle + circle + circle + circle = 76, then circle = (), triangle = ()
