2/6 divided by 6/8 is an answer
-4x-y=24
-4x=y+24
Y=-4x-24
Now that we have the question, we can plug numbers in for x to get y-coords.
-4(0)-24
-24
(0,-24)
-4(1)-24
-4-24
(1,-28)
he difference between the expressions (2x² + 6x – 11) and (5x² – x + 5) will be –3x² + 7x – 18. Then the correct option is D.
<h3>What is subtraction?</h3>
It simply implies subtracting something from an entity, group, location, etc. Subtracting from a collection or a list of ways is known as subtraction.
The expressions are given below.
(2x² + 6x – 11) and (5x² – x + 5)
Then the difference between the expressions (2x² + 6x – 11) and (5x² – x + 5) will be
⇒ (2x² + 6x – 11) - (5x² – x + 5)
⇒2x² + 6x – 11 – 5x² + x – 5
⇒ –3x² + 7x – 18
Then the correct option is D.
The complete expression is given below.
(2x² + 6x – 11) and (5x² – x + 5)

Answer:
B
Step-by-step explanation:
given
A = ( + )h
multiply both sides by 2 to eliminate the fraction
2A = ( + )h
divide both sides by the multiplier h
= +
Subtract from both sides
- = , that is
= -
Let
x--------> the total length of the water main
we know that
the number of 20 ft pipes is x/20
and
the number of 18 ft pipes is x/18
Since they differ by 14 pipes,
we have the equation
x/18 - x/20 = 14
Solve for x (by canceling fractions)
20x - 18x = 14*18*20
x = (14*18*20)/2
x = 2,520 ft
therefore
the answer is
the total length of the water main is 2,520 ft
