1.25x+2.5 <2.75x-6.5 =>
=> 2.75x-1.25x > 2.5+6.5 =>
=>  1.5x > 9 =>
=> x > 6
So A is the correct answer~~
Hope that helps! :)

The area A of a triangle with base b and height h is given by A = = bh. Find the area when b = 18 m (meters) and h = 30 m.
Pie

Answer:

Area = 270m^2

Step-by-step explanation:

Given

A = \frac{1}{2}bh

b = 18m

h = 30m

Required

Solve for A

Simply substitute 18 for b and 30 for h

A = \frac{1}{2}bh

A = \frac{1}{2} * 18 * 30

A = 270

Hence:

The area is

Area = 270m^2

The end point P of a line segment PQ(-3,6) and its mid point is (5,8) Find the coordinates of the end point Q
Georgia [21]

Answer:

  • (13, 10)

Step-by-step explanation:

Let Q have coordinates x and y

<u>Using midpoint formula we find the values of x and y</u>

  • (- 3 + x)/2 = 5 ⇒ -3 + x = 10 ⇒ x = 10 + 3 ⇒ x = 13
  • (6 + y)/2 = 8 ⇒ 6 + y = 16 ⇒ y = 16 - 6 ⇒ y = 10
  • Q = (13, 10)
