(a) first write an equation you can use to answer this question. use  x  as your variable.

15 hours of labor was needed to complete the job.

Step-by-step explanation:

James was charged a total of $1660.

Let x be the number of hours the plumber worked.

Cost of the parts = $460

Hourly rate of labor = $80

We can compile all this information in an equation form as:

Now solving for x;

=>

So, x = 15

Hence, 15 hours of labor was needed to complete the job.

step-by-step explanation:

a rhombus is a parallelogram enjoying his symmetry.

d) 30 units^2

area of rectangle = l × b

we know,

length = 10 unit

breadth = 3 unit

applying the formula,

= l × b

= 10 × 3

= 30 unit^2
