Answer:
x = 1.6Step-by-step explanation:
[tex] - 2.5(4x - 4) = - 6 \\ - 2.5(4x) - 2.5( - 4) = - 6 \\ - 10x + 10 = - 6 \\ - 10x + 10 - 10 = - 6 - 10 \\ - 10x = - 16 \\ \frac{ - 10x}{ - 10} = \frac{ - 16}{ - 10} \\ x = 1.6 \\ [/tex]

Answer:
the first one ⇒ -27/20
Step-by-step explanation:
hope this helps :)
Answer:
-27/20
Step-by-step explanation:
Step 1: Flip the division symbol into a multiplication symbol, and flip the fraction -4/9.
[tex]\frac{3}{5}/(-\frac{4}{9}[/tex] [tex]\frac{3}{5} * (-\frac{9}{4})[/tex]Step 2: Multiply.
[tex]\frac{3}{5} * -\frac{9}{4}[/tex] [tex]\frac{3*(-9)}{5*4}[/tex] [tex]\frac{-27}{20}[/tex] [tex]-\frac{27}{20}[/tex]Therefore, the answer is -27/20.
Classify the four angles of the quadrilateral
Answer:
<A = right angle
<B = acute angle
<C = obtuse angle
<D = acute angle
Step-by-step explanation:
Right angle = 90 degrees
Acute angle = less than 90 degrees
Obtuse angle = more than 90 degrees
∠A = 90° is a right angle, ∠B = 60° and ∠D = 70° are acute angles,
and ∠C = 140° is an obtuse angle.
We have,
The quadrilateral ABCD.
There are four angles:
∠A = 90°
∠B = 60°
∠C = 140°
∠D = 70°
An acute angle is an angle whose measure is less than 90 degrees.
An obtuse angle is an angle whose measure is greater than 90 degrees but less than 180 degrees.
A straight angle is an angle whose measure is 90 degrees.
Using the definition,
∠A = 90°
This is a right angle.
∠B = 60°
This is an acute angle.
∠C = 140°
This is an obtuse angle.
∠D = 70°
This is an acute angle.
Thus,
∠A = 90° is a right angle, ∠B = 60° and ∠D = 70° are acute angles,
and ∠C = 140° is an obtuse angle.

Consider the line - 5x+2y=8.
Find the equation of the line that is parallel to this line and passes through the point (-5, -3).
Find the equation of the line that is perpendicular to this line and passes through the point (-5, -3).
Answer:
The parallel equation is y=[tex]\frac{5}{2}[/tex]x-5.
The perpendicular equation is y=[tex]\frac{-2}{5}[/tex]x-5.
Step-by-step explanation:
First solve for y.
-5x+2y=8
2y=5x+8
y=[tex]\frac{5}{2}[/tex]x+4
A line is parallel if it has the same slope, but different y-intercepts.
The y-intercept of the given point is -5, so the new slope will be y=[tex]\frac{5}{2}[/tex]x-5
To find a perpendicular line, you find the negative reciprocal of the given slope.
So you find [tex]\frac{-1}{\frac{5}{2} }[/tex], which is equal to [tex]\frac{-2}{5}[/tex].
The perpendicular equation is y=[tex]\frac{-2}{5}[/tex]x-5.
Answer:
Step-by-step explanation:

A running tap dispenses 0.14 gallons of water every second. How many pints of water is dispensed after 50 seconds? Show your work.
Answer:
56
Step-by-step explanation:
0.14 gallons/sec * 50 sec = 7 gallons
There are 8 pints per gallon.
7 gallons * 8 pints/gallon = 56 pints
Given that a running tap dispenses 0.14 gallons of water every second. Using unitary method, 56 pints of water is dispensed after 50 seconds.
What is unitary method?The unitary method is a technique for solving a problem by first finding the value of a single unit, and then finding the necessary value by multiplying the single unit value.
Water dispensed every second = 0.14 gallons
Water dispensed after 50 seconds = 0.14 * 50 = 7 gallons = 7 * 8 = 56 pints (1 gallon = 8 pints)

Help please I need to find x and y
Answer:
[tex]x=6\\y=12[/tex]
Step-by-step explanation:
To find the value of x you can use sin rule
[tex]sin(60)=\frac{oppoaite}{hypotenuse}\\\frac{\sqrt{3} }{2} =\frac{x}{4\sqrt{3} } \\[/tex]
Use cross multiplication
[tex]4*\sqrt{3} *\sqrt{3} =2x\\4*3=2x\\12=2x\\\frac{12}{2} =\frac{2x}{2} \\6 =x[/tex]
To find the value of y you have to use sin rule again
[tex]sin(30)=\frac{opposite}{hypotenuse}\\\frac{1}{2} =\frac{x}{y} \\\frac{1}{2} =\frac{6}{y} \\[/tex]
Use cross multiplication
[tex]y=6*2\\y=12[/tex]
