Suppose 2kg of sugar contains 9*10 crystals.
how many sugar crystals are there in 5 kg of )1.2kg of sugar

225

Step-by-step explanation:

9*10 = 9 times 10 = 90

2kg = 90

that means 1kg = half of 90 = 45

1kg = 45

5 kg = 45 times 5 = 225

By the way at the end of your question you put "2)1.2kg of sugar" but I don't know what that is so i ignored it

a net is a diagram that shows a “flattened” view of a solid. in a net, each face and base is shown with all of its dimensions. a net can also serve as a pattern to build a three-dimensional solid.

a pyramid is a three-dimensional object with a base that is a polygon and triangular faces that meet at one vertex.

" the net of a triangular pyramid consists of four triangles. the base here we are given of the pyramid is a equilateral   triangle, and the lateral faces are also triangles "

1. x> -5

2. x< 8

step-by-step explanation:

1. 2x> -10

divide by 2 from both sides of equation.

2x/2> -10/2

simplify, to find the answer.

-10/2=-5

x> -5 is the correct answer.

2. 3x< 24

divide by 3 from both sides of equation.

3x/3< 24/3

simplify, to find the answer.

24/3=8

x< 8 is the correct answer.

i hope this you, and have a wonderful day!
