Tony has x quarters. Jane has three more quarters than Tony. Rob has twice as many quarters as Jane. Together, Rob and Jane have $4.50 in quarters. Complete each statement. (A) The expression x + 3 represents the number of quarters Jane has. (B) The expression x – 3 represents the number of quarters Rob has. (C) Tony has quarters.

x = 3 quarters

Step-by-step explanation:

Tony = x quarters

Jane = (x + 3) quarters

Rob = 2(x + 3) quarters

Rob and Jane have $4.50 in quarters.

$1 = 4 quarters.

$4.50 = ( 4 × 4.5 ) quarters

= 18 quarters.

(x + 3) + 2(x + 3) = 18

x + 3 + 2x + 6 = 18

3x + 9 = 18

3x = 18 - 9

3x = 9

x = 9/3

x = 3

(A) The expression x + 3 represents the number of quarters Jane has. YES

x + 3

= 3 + 3

= 6 quarters

(B) The expression x – 3 represents the number of quarters Rob has.

NO

(C) Tony has quarters.

Tony = x quarters

= 3 quarters

Rob = 2(x + 3) quarters

= 2(3 + 3) quarters

= 2(6) quarters

= 12 quarters

step-by-step explanation:

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 "
