Answer:
[tex]\boxed {x = 6}[/tex]
Step-by-step explanation:
Solve for the value of [tex]x[/tex]:
[tex]0.4x + 0.4 = 0.6x - 0.8[/tex]
-Take [tex]0.6x[/tex] and subtract it from [tex]0.4x[/tex]:
[tex]0.4x + 0.4 - 0.6x = 0.6x - 0.6x - 0.8[/tex]
[tex]-0.2x + 0.4 = - 0.8[/tex]
-Subtract [tex]0.4[/tex] to both sides:
[tex]-0.2x + 0.4 - 0.4 = - 0.8 - 0.4[/tex]
[tex]-0.2x = -1.2[/tex]
-Divide both sides by [tex]-0.2[/tex]:
[tex]\frac{-0.2x}{-0.2} = \frac{-1.2}{-0.2}[/tex]
-Expand by multiplying the numerator and the denominator by [tex]10[/tex]:
[tex]x = \frac{-12}{-2}[/tex]
[tex]\boxed {x = 6}[/tex]
So, the value of [tex]x[/tex] is [tex]6[/tex].
When you are driving a car, the number of miles that you can drive is directly proportional to the amount of gas you have left in the tank. For instance, if you only have 2 gallons of gas left, you can only travel 26 more miles. If I need to travel 91 miles, how many gallons of gas would I need?

How do you convert a repeating decimal into a fraction? Because, I was asked this question: Rewrite as a simplified fraction. 3.24=?
Answer:
3 6/25
Step-by-step explanation:
Rewrite the decimal number as a fraction with 1 in the denominator
3.24=3.24/1
Multiply to remove 2 decimal places. you multiply top and bottom by 10^2 = 100
3.24/1×100/100=324/100
Find the Greatest Common Factor of 324 and 100. reduce the fraction by dividing both numerator and denominator by GCF = 4,
324÷4 over 100÷4=81/25
Simplify the improper fraction
=3 & 6/25
A 21 foot tower must be secured with a wire anchored 7 feet from the base of the tower. What angle will the wire make with the ground? Round your answer to the nearest tenth.
Answer:
71.6
Step-by-step explanation:
opposite=height= 21 ft
Adjacent= length of shadow = 7ft
Angle of inclination= C
tan C = 21/7
C= tan‐¹(3)= 71.6
hellppp meeeeee......
Angle 4 and 7= Interior angles
Angle 12 and 16= Corresponding angles
Angle 1 and 14= Alternate exterior angles
Angle 5 and 10=Alternate angles
angle 6 and 7 are alternate angles I think.
What is the value of
[tex]( \frac{3 {}^{0} }{27? \frac{2}{3} } ) {}^{1} [/tex]
A. - 9
B. 9
C.-1/9
D.1/9
Answer:
D
Step-by-step explanation:
You can ignore the power, since taking something to the power of one doesn't change the answer.
Anything to the 0 is going to be 1, so the answer is one over something.
The denominator is clearly going to be positive, regardless of what the symbol is.
With this in mind, it seems like the answer should be 1/9.

Is the following statement a biconditional?
If Maura is going to the library, then she is bringing her favorite binder.
yes
no
This is a regular conditional expression because it is in the form "If P, then Q"
P = Maura is going to the library
Q = she is bringing her favorite binder
A biconditional is of the form "P if and only if Q"
The "if and only if" is the key phrase needed. It allows us to swap the positions of P and Q to say "Q if and only if P".

A basket ball team played six games. In those games, the team won by 8 points, lost by 10, won by 7, won by 10, lost by 3, and won by 6. What was the mean difference in game scores over the six games?
Answer: 3
Step-by-step explanation:
Mean simply means average. To calculate mean,we add together all the numbers given and divide them by the amount of numbers.
The Mean here will be:
= [8 +(-10) + 7 + 10 + (-3) + 6]/6
=18/6
= 3
The mean is 3

8х + 7y= -5
X= -3y - 7
Answer:
x = 2
y = -3
Step-by-step explanation:
Step 1: Write systems of equation
8x + 7y = -5
x = -3y - 7
Step 2: Solve for y
Substitute 2nd equation into 1st: 8(-3y - 7) + 7y = -5Distribute 8: -24y - 56 + 7y = -5Combine like terms: -17y - 56 = -5Add 56 to both sides: -17y = 51Divide both sides by -17: y = -3Step 3: Solve for x
Substitute y to find x: x = -3(-3) - 7Multiply: x = 9 - 7Subtract: x = 2Step 4: Check
Plug in x, y into an original equation to verify it's a solution.
2 = -3(-3) - 7
2 = 9 - 7
2 = 2
Answer:
x=2 y=-3

A sealed rectangular container 4 cm by 8 cm by 16 cm is sitting on its smallest face. In this position the water level is 4 cm from the top. How many centimeters from the bottom will the water level reach if the container is turned and placed on its largest face?
Answer:
height of water in the container is 3 cm.
Step-by-step explanation:
Given;
A sealed rectangular container, measuring 4 cm by 8 cm by 16 cm
the height of the container is 16 cm, when filled with water at 4 cm level from the top, thus, the height of water in the container is (16 cm - 4cm) = 12cm
Volume of water in the container when it is sitting on its smallest face = 4 cm x 8 cm x 12 cm = 384 cm³
Volume of water in the container when it is sitting on its largest face = 8 cm x 16 cm x h
where;
h is height of water in the container
384 = 8 x 16 x h
384 = 128h
h = 384 / 128
h = 3 cm
Therefore, height of water in the container is 3 cm.

The slope of a line is -4, and the y-intercept is -3. What is the equation of the line written in slope-intercept form?
y = 4x - 3
y = -4x + 3
y = -4x - 3
Answer:
y = - 4x - 3
Step-by-step explanation:
The equation of a line in slope- intercept form is
y = mx + c ( m is the slope and c the y- intercept )
Here m = - 4 and c = - 3 , thus
y = - 4x - 3 ← equation of line
Hii!
__________________________________________________________
Answer:
Below is all the info you need! ^^
Step-by-step explanation:
Do you remember the slope intercept formula?
y=mx+c is the formula, in which m denotes the slope and c denotes the y intercept.
Suppose we have the slope m and the y intercept c. What is the equation? y=mx+c.
Similarly, if we have the slope -4, and the y intercept -3, the equation is y=-4x+(-3), or y=-4x-3.

A. 49
B. 14
C. 71
D. 7
E. 7
F. 7.
Using the Pythagorean Theorem, it is found that the length of the diagonal of the square shown below is given by:
F. [tex]h = 7\sqrt{2}[/tex]
What is the Pythagorean Theorem?The Pythagorean Theorem relates the length of the legs [tex]l_1[/tex] and [tex]l_2[/tex] of a right triangle with the length of the hypotenuse h, according to the following equation:
[tex]h^2 = l_1^2 + l_2^2[/tex]
In this problem, the diagonal is the hypotenuse, while the legs are the sides of [tex]l_1 = l_2 = 7[/tex], hence:
[tex]h^2 = l_1^2 + l_2^2[/tex]
[tex]h^2 = 7^2 + 7^2[/tex]
[tex]h^2 = 2 \times 49[/tex]
[tex]h = \sqrt{2 \times 49}[/tex]
[tex]h = 7\sqrt{2}[/tex]
Hence option F is correct.
