What is 2 3 (−7) + 2 3 (−5)
DochEvi [55]

Answer:

Step-by-step explanation:

Multiply 2/3 and your number. If you have a whole number, convert it to a fraction by putting it over a denominator of 1. When multiplying fractions, calculate numerator times numerator, then denominator times denominator. For example, to find two-thirds of 18, multiply 2/3 x 18/1 to get 36/3.

Reduce the resulting fraction as needed by dividing it by the common denominator. For example, the common denominator of 36 and 3 is 3. Diving 36 and 3 by 3 gives you a fraction of 12/1, which is the same as 12. Thus, two-thirds of 18 is 12.

Which statement about the net is true?
Schach [20]
The net cannot be folded to form a pyramid because the faces that are not a base are not all triangles

If you fold this net up, you will get a triangular prism, NOT A PYRAMID.

A pyramid can have ANY polygon as its base, as long as all the other rest of the shapes are triangles.

Depending on the base, the number of triangles in a net of a pyramid must match the number of sides its particular base has.

For example, if you have a square pyramid turned into a net:
The base is a square (4 sides)
There should be 4 triangles on each side.

Because a pyramid is where all the triangles must meet up at a point.

Hope this helps!

What is the answer to 16a5 b3/8ab ?
marishachu [46]

Answer:

When we are dividing exponents, there is this rule:

\frac{a^n}{a^m}=a^{(n-m)}

So, in our case we have this:

\frac{16a^5b^3}{8ab} = \frac{16}{8}a^{(5-1)}b^{(3-1)}=2a^4b^2

Suppose that b and c are points on the number line . if bc = 10 and b lies at 3 , where could c be located?
katrin [286]
C would be located around 3.3

Bc=10 meaning b x c= 10
B lies at 3
(Opposite of time is division as you probably already know) so 10/3 is 3.3

(I’m sorry if this wrong but hope it is not and you understand it)
