Answer:

x = 4

Step-by-step explanation:

3x - 6y = 18

2x + 2y = 6 -> 3(2x + 2y = 6)

3x - 6y = 18 -> Cross out - 6y

6x + 6y = 18 -> Cross out + 6y

9x = 36 -> Divide 9 on both sides.

X = 4

Answer: x=4, y=-1

Step-by-step explanation:

Make a table of solutions that work for 2x+2y=6

0,3

1,2

2,1

3,0

4,-1

Now try them in 3x-6y=18

The one that works is 4,-1

A company rents water tanks shaped like cylinders. Each tank has a radius of 5 feet and a height of 3 feet. The cost is 3 per cu
vova2212 [387]

Answer: the cost of renting one water tank is 706.5

Step-by-step explanation:

The formula for determining the volume of a cylinder is expressed as

Volume = πr²h

Where

r represents the radius of the cylinder.

h represents the height of the cylinder.

π is a constant whose value is 3.14

From the given information,

Radius = 5 feet

Height = 3 feet

Therefore,

Volume = 3.14 × 5² × 3 = 235.5 cubic feet.

If the cost is 3 per cubic foot, then the cost of renting one water tank is

235.5 × 3 = 706.5

What is the area of the shape below?
Morgarella [4.7K]

Answer:

30 yd²

Step-by-step explanation:

Hello There!

The shown figure is a trapezoid

The first thing we need to do is figure out what the formula for area of a trapezoid is

A=\frac{a+b}{2} h

where a and b = bases and h = height

we are given all of the dimensions so all we have to do is plug in the values

a = 9

b = 6

h = 4

A = \frac{6+9}{2} 4\\6+9=15\\\frac{15}{2} =7.5\\7.5*4=30

so we can conclude that the area of the figure is

30 yd²

Find the slope and y-intercept of the linear equation below.<br>2x-3y=15
kotegsom [21]
Y = mx + b
m = slope
b = intercept
So if you make it into that it's
y = 2/3x - 5
So then you get the slope as -5 and also the slope as 2/3
