Answer:
x = 7/2
Step-by-step explanation:
The whole triangle is an equilateral triangle--all the sides are the same: 7, 7, 7 and all the angles are equal: 60°, 60°, 60°.
So the line thru the triangle makes two 30°-60°-90° triangles. The shortest side of the right triangle is half the length of the hypotenuse. Also, the line cuts the angle in half (30° and 30°) and also the side: 7/2
Answer:
x + x + 7 + x -4 = 300
3x = 297
x = 99 First Piece
x2 = 106 Second Piece
x3 = 95 Third piece

Answer:
80g:40g:17
Step-by-step explanation:
400g : 2.1kg : 085
400g : 200g : 085
80g : 40g : 17
You need to do 9 x 6, it would equal 45. Now, minus 60 - 45. The leftover plates would be 15.
If my math is correct is should be 2 and 2/5. sorry if that's wrong
