Answer:
3.1x+2.8z
3.1 over 10x +14 over 15 z
1 over 10 x (3.1x + 2.8z)
4.3x - 1.2z =
43 over 10x - 6 over 5z
1 over 10 x (43x-12z)
Answer:
Shape a has 1 order of rotational symmetry and 1 line of symmetry
Shape b has 2 orders of rotational symmetry and 0 line of symmetry
Rotational symmetry is how many times a shape can be rotated and look the same.
Lines of symmetry are how lines can be put through the shape to make it symmetrical or the same on both sides
We can make 64 different equations using the power of ten.
<h3>What is the power of a number?</h3>
The power of a number identifies how many times that particular number is multiplied by itself.
Here, let us assume that the different equations = x
Using a power of 10, we have 10x making a total of 640.
Divide both sides by 10
10x/10 = 640/10
x = 64
Therefore, we can conclude that we can make 64 different equations using the power of ten.
