4x + 5y = 22 ⇒ Equation 1
2x + 3y = 12 ⇒ Equation 2

2(2x + 3y) = 2(12)
4x + 6y = 24 ⇒ Equation 3

Equation 1 - 3
(4x - 4x) + (5y - 6y) = 22 - 24
-y = -2
y = 2

Substitude y into Equation 1,
4x + 5(2) = 22
4x + 10 = 22
4x = 12
x = 3

Hunter-Best [27]

Answer:

a) 50.24 ft²

b) 150.72 ft²

Step-by-step explanation:

Jason is painting a large circle on one wall of his new apartment. The largest distance across the circle will be 8 feet.

The distance across a circle is also called a diameter, Hence,

D = Diameter = 8 ft

The Area of a circle = πr²

r = Diameter/2 = 8ft/2 = 4ft

π = 3.14

Hence,

The Area of the circle = π × (4 ft)²

= 50.24 ft²

a) Approximately the amount of wall the circle will cover is 50.24 ft².

b) How much area will he cover if he painted a circle on three walls?

This is calculated as:

1 wall = 50.24 ft²

3 walls = x

Cross Multiply

x = 3 × 50.24 ft²

x = 150.72 ft²

The point A has co-ordinates (-4,6) and the point B has co-ordinates (7,-2).
Serhud [2]

Answer:

√185 or 13.60 units to the nearest hundredth.

Step-by-step explanation:

For the points (x1,y1) and (x2,y2) the length between the points is given by:

L = √ [ (x2-x1)^2 + (y2-y1)^]

So here we have:

Length of AB  √ [ (7- - 4)^2 + (-2 - 6)^2]

=  √ (121 + 64)

= √185.
