To install a drain pipe, a team of 3 workersmust dig a rectangular trench, 1.5m wide, 2.5m deep and 6.Om long. Draw and label a diagram.
a) Calculate the volume of earth that must be dug up.
b) If each worker can dig 1.5 m of earth per hour, how long will it take to dig the trench?

answer: 457.14

step-by-step explanation:

205 - 45 = 160

160 / .35 = 457.142857

it is x equals 3   plese mark me really need it

step-by-step explanation:

this linear equation would have just one solution.

step-by-step explanation:

the reason why this would have one solution is that it is an expression with just one variable. since that variable is not raised to a power, it will always have just one solution.

the equation of the parallel line would be y = 2x + 9

step-by-step explanation:

to start we need to find the slope of the original line. we can do that by looking at the coefficient of x, which is 2

since the slope of the original line is 2 and parallel lines have the same slope, we know the new line will also have 2 slope. now we can use that along with the point given in point-slope form to get the find equation.

y - y1 = m(x - x1)

y - 5 = 2(x + 2)

y - 5 = 2x + 4

y = 2x + 9
