The value of x - coordinate is 14.4

<em><u>Solution:</u></em>

Given that we have to find the x -coordinate of the system

<em><u>Given system of equations are:</u></em>

2x + 3y = 144 -------- eqn 1

y - x = 24 --------- eqn 2

Solve the above system of equations to find the x - coordinate

From eqn 2,

y = 24 + x ------- eqn 3

Substitute eqn 3 in eqn 1

2x + 3(24 + x) = 144

2x + 72 + 3x = 144

Add the like terms

5x + 72 = 144

5x = 144 - 72

5x = 72

Divide 72 by 5

x = 14.4

Thus the x - coordinate of the system is 14.4

The city is replacing all the streets, curbs, and gutters in Middleville. The homeowners on both sides of the street are charged
bija089 [108]
Mr. Kyle will be expected to pay $8,100.

The total cost for his land would be 120 x 90 = 10,800.

Since the city is paying 25%, he must pay the other 75%.

0.75 x 10800 = 8100

Length of a rectangular prism is increased by factor of 1.5. The width is doubled and height is tripled. What is the new volume?
dimulka [17.4K]

Nine times the original volume

Step-by-step explanation:

Let the length, width and height of the rectangular prism be 'l' 'w' and 'h'.

The volume of the rectangular prism is given by,

V = W x l x h

The original volume of the rectangular prism is,

V = wlh

Here the length is 1.5 the original length

So, l = 1.5 x l = (1.5l)

And the with is doubled. So,

W = 2W

The height is tripled. So,

h = 3h

Volume of the new rectangular prism is,

V = (1.5l) (2w) (3h)

V = 9 wlh

We know that wlh is the original volume of the rectangular prism.

So the new volume is 9 times the original volume.
