The cost of glass is:  £4

The cost of mug =  £2

Step-by-step explanation:

Let g be the number of glasses and

m be the number of mugs

3g+3m = 18\ \ \ \ \ Eqn\ 1\\6g+4m=32\ \ \ \ \ Eqn\ 2

Multiplying equation 1 by 2

6g+6m=36\ \ \ \ Eqn\ 3

Subtracting Eqn 2 from Eqn 3

6g+6m - (6g+4m) = 36-32\\6g+6m-6g-4m=4\\2m=4

Dividing both sides by 2

\frac{2m}{2} = \frac{4}{2}\\m = 2

Putting m=2 in eqn 1

3g+3(2) = 18\\3g+6 = 18\\3g = 18-6\\3g = 12

Dividing both sides by 3

\frac{3g}{3} = \frac{12}{3}\\g = 4

Hence,

The cost of glass is:  £4

The cost of mug =  £2

Alex

Answer:

Step-by-step explanation:

b) 1- scale factor from the first map to the second map:

\frac{8}{6}  = 1.33

   2- landmark on the first map is a triangle with side lengths of 3 mm, 4 mm, and 5 mm.

Side lengths of the landmark on the second map

Divide the length by scale factor:

side lengths of 3 mm:  \frac{3}{1.33} = 2.25 mm

side lengths of 4 mm:  \frac{4}{1.33} = 3.007 mm

side lengths of 5 mm:  \frac{5}{1.33} = 3.75 mm

Two garden plots are to have the same area. One is square and one is rectangular. The rectangular plot is 4 meters wide and 16 m
AlexFokin [52]

side = 8 m

the area of the rectangle = length × width = 16 × 4 = 64 m²

the area of the square = s² ( where s is the length of a side ), hence

s² = 64 ( since areas are equal )

take the square root of both sides

s = √64 = 8 m
