Answer:

Lanza is correct.

Step-by-step explanation:

The two missing dimensions on the left are 4.5 m on the vertical line, and 5 m on the horizontal line.

These dimensions let us partition the garden a number of ways. One way is ...

a rectangle 9 m by 4.5 m
a rectangle 4 m by 3.5 m

The total of the areas of these is ...

(9)(4.5) +4(3.5) = 40.5 +14 = 54.5 . . . . square meters

At £16 per square meter, Lanza's charge will be ...

£16 × 54.5 = £872

Lanza is correct that she will have to charge more than £800.

Answer:

${ \tt{ \frac{7x}{3} + 2 = - 15 }} \\ \\ { \tt{ \frac{7x + 6}{3} = - 15 }} \\ \\ { \tt{7x + 6 = - 15 \times 3}} \\ \\ { \tt{7x + 6 = - 45}} \\ \\ { \tt{7x = - 45 - 6}} \\ \\ { \tt{7x = - 51}} \\ \\ { \boxed{ \tt{x = - 7.3}}}$

Answer:

yes it is.

x = 4 and y = -3

Step-by-step explanation:

Solve simultaneously using elimination method:

equation 1 - equation 2

3x + y = 9 equation 1

-2x + y = 5 equation 2

_________

x = 4

plug 4 into any of the 2 equations and solve for y.

3(4) + y = 9

12 + y = 9

12-12 + y = 9-12

y = -3
