Answer:

x<-3

This means numbers less than -3 are solutions.

Step-by-step explanation:

9(2x+1)<9x-18  is the given inequality.

Distributive property applied:

18x+9<9x-18    

Subtracting 9x on both sides:

9x+9<      -18

Subtracting 9 on both sides:

9x    <      -27

Dividing both sides by 9:

 x     <        -3

The solution is x<-3 which means anything less than -3 is a solution.

Answer:

x < -3

Step-by-step explanation:

using the distributive property, distribute 9(2x +1) so it's 18x + 9, subtract 9x from 18x, subtract 9 from -18, divide both sides by 9, x < -3

A right cylindrical tank with a total volume of 5,000 cubic units has an interior diameter of 20 units. the volume gauge indicat
vovikov84 [41]
Total volume of the tank is 5000 cubic units
Volume of liquid=60%*5000=3000 cubic units
the height of the fluid will be found as follows
V=πr²h
where:
r=20/2=10 units
hence:plugging in the values and solving for h we get:
3000=π×(10²)×h
thus
h=3000/(100π)
h=9.5292966
h=9.5293 units

Solve for k: 8k + 2m=3m+4
Andreyy89

Isolate the k. Note the equal sign. What you do to one side, you do to the other.

First, subtract 2m from both sides

8k + 2m (-2m) = 3m (-2m) + 4

8k = m + 4

Next, divide 8 from both sides

(8k)/8 = (m + 4)/8

k = (m + 4)/8

k = m/8 + 1/2

k = m/8 + 1/2 is your answer

hope this helps

Find the equation that represents a line that passes through the point (7,-5) and has slope -4/7
Evgen [1.6K]

Answer:

The equation would be y = -4/7x - 1

Step-by-step explanation:

Given that we have the slope and the point, we can solve for the equation using point-slope form.

y - y1 = m(x - x1)

y + 5 = -4/7(x - 7)

y + 5 = -4/7x + 4

y = -4/7x - 1

What is the volume of the cylinder?
Vlada [557]
Volume= pi times radius squared times height.
So the diameter is 16, if you divide by 2 you'll get the radius. 16/2=8
So the answer is 3.14x8^2x10
8 squared is 64
So 3.14x64x10 = 2,010.62 
Answer is C
