Car X weighs 136 pounds more than car Z. Car Y weighs 117 pounds more than car Z. The total weight of all three cars is 9439 pou
Aleksandr [31]

Let x, y and z denote the weighs of car X, car Y and car Z, respectively.

We know that car X weighs 136 more than car Z, this can be express by the equation:

x=z+136

We also know that Y weighs 117 pounds more than car Z, this can be express as:

y=z+117

Finally, we know that the total weight of all the cars is 9439, then we have:

x+y+z=9439

Hence, we have the system of the equations:

\begin{gathered} x=z+136 \\ y=z+117 \\ z+y+z=9439 \end{gathered}

To solve the system we can plug the values of x and y, given in the first two equations, in the last equation; then we have:

\begin{gathered} z+136+z+117+z=9439 \\ 3z=9439-136-117 \\ 3z=9186 \\ z=\frac{9186}{3} \\ z=3062 \end{gathered}

Now that we have the value of z we plug it in the first two equations to find x and y:

\begin{gathered} x=3062+136=3198 \\ y=3062+117=3179 \end{gathered}

Therefore, car X weighs 3198 pound, car Y weighs 3179 pounds and car Z weighs 3062 pounds.

(Geometry)<br> Could anyone help me with this please and thanks
Ket [755]

Answer:

z = 32/3

Step-by-step explanation:

Presuming all the horizontal lines are parallel, the ratios of lengths will be identical.

3/8 = 4/z

3z = 8(4)

z = 32/3

7. Find DE.<br> 11-25<br> E<br> А<br> 4x + 1<br> D<br> С
Arlecino [84]

Answer:

  • DE = 37

Step-by-step explanation:

AD = DC and BE=EC ⇒

DE = 1/2AB

  • 4x + 1 = 1/2(11x - 25)
  • 2(4x + 1) = 11x - 25
  • 8x + 2 = 11x - 25
  • 11x - 8x = 2 + 25
  • 3x = 27
  • x = 27/3
  • x = 9

DE = 4*9 + 1 = 36 + 1 = 37
