Answer:  The required value of x is -52.

Step-by-step explanation:  We are given to find the value of x from the following equation :

x+58=6~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~(i)

To find the value of x, we need to solve the equation (i).

The solution of equation (i) is as follows :

x+58=6\\\\\Rightarrow x=6-58\\\\\Rightarrow x=-52.

Thus, the required value of x is -52.

If PQR is a triangle,given that /PQ\=15m, /QR\=17m and /RP\=18m.Find the area of the triangle to the nearest whole number.
nydimaria [60]

Answer:

118.3 m²

Step-by-step explanation:

Step 1. Calculate the <em>semiperimeter</em> (s).

s = (p + q + r)/2

s = (17 + 18+ 15)/2  

s = 50/2

s = 25 m

===============

Step 2. Calculate the <em>area</em> (A).

Use <em>Heron’s formula</em>:

A = \sqrt{s(s-p)(s-q)(s-r)}

A = \sqrt{25(25-17)(25-18)(25-15)}

A = \sqrt{25\times8\times7\times10}

A = \sqrt{14 000}

A = 20\sqrt{35}

A = 118.3 m²

Dovator [93]

Answer:

  x = 200

Step-by-step explanation:

Multiply by 4:

  x + 120 + 2x = 720

  3x = 600 . . . . . . collect terms, subtract 120

  x = 200 . . . . . . . divide by 3

_____

<em>Check</em>

  (200/4 +30) +(200/2) = 180

  (50 +30) + 100 = 180

  80 + 100 = 180 . . . . . true

_____ _____

<em>Alternate solution</em>

If you like, you can simply work with the equation given.

  (3/4)x + 30 = 180 . . . . collect terms

  (3/4)x = 150 . . . . . . . . . subtract 30

  x = 200 . . . . . . . . . . . . multiply by 4/3
