\(\frac{-4}{5}x +7=-13\) Find the value of x
Answers
Answer: x = 25
Step-by-step explanation:
\(-\frac{4}{5} x + 7=-13\)
1. First get X by itself by subtracting 7 from both sides
\(-\frac{4}{5} x=-20\)
2. Multiply by the reciprocal of 4/5 on both sides
\((-\frac{5}{4} )-\frac{4}{5} x=-20(-\frac{5}{4} )\)

Answer:
D. 1200 gallons
Step-by-step explanation:
Fractions of the total are given, as is the quantity the difference of those fractions represents. These can be used to write an equation to find the total.
SetupLet g represent the total number of gallons of fuel sold. Then the number of gallons of 87-octane sold is 0.50g, and the number of gallons of 89-octane sold is 0.35g. The difference is said to be 180 gallons:
0.50g -0.35g = 180
SolutionCollecting terms gives ...
0.15g = 180
Dividing by the coefficient of g, we find ...
g = 180/0.15 = 1200
The gas station sold 1200 gallons of fuel last weekend.

Additional comment
That's 600 gallons of 87-octane; 420 gallons of 89-octane; 120 gallons of 92-octane; and 60 gallons of 99-octane.

Answers
Answer:
x = 28
Step-by-step explanation:
1) Add 21 to both sides of the equation.
-4x - 21 + 21 = 91 + 21
2) Simplify
A. Add the numbers
-4x = 91 + 21
B. Add the numbers
-4x = 112
3) Divide both sides of the equation by the same term.
-4x/4 = 112/-4
4) Simplify
A. Cancel terms that are in both the numerator and denominator
x = 112/-4
B. Divide the numbers
x = 28
21
to both sides of the equation
−4 −21 = 91
−4 −21 + 21 =91+21
Then it will be = −28

You find the constant or proportionality by put y/x
(15,45) is in the form (x,y) The x is 15 and the y is 45. Put this in the form y/x and you get 45/15 or 3. 3 is the constant of proportionality.
y = 3x

In this discussion, you have the opportunity to have some hands-on fun. With a
tape measure determine the diameter and circumference of at least three circular
objects. Calculate the ratio of the circumference to the diameter.
Take a look at Khianna's post:

OJ Can
Diameter
1.5 in
8 in
6 in
Trash Can
3.12
24.96 in
18.8 in
Lamp Shade
3.13
The ratio was close to Pi, but never actually equaled 3.14, maybe because of an
error when I measured the objects.
After you complete your measurements, use the diameter to calculate the exact
circumference of each object as shown on the next page.
Use the diameter to calculate the exact.value of the circumference of each object.
Look how Khianna added to her post:

Explanation:
Let the mass of one paperback be 'p' and one textbook be 't'.
Equation one:
sum of mass = total mass in box
20p + 9t = 44.4Equation two:
20p + 5p + 9t + 1t = 5125p + 10t = 51make 't' subject
10t = 51 - 25pt = 5.1 - 2.5pInsert this into equation one:
20p + 9(5.1 - 2.5p) = 44.4
20p + 45.9 - 22.5p = 44.4
20p - 22.5p = 44.4 - 45.9
-2.5p = -1.5
p = 0.6
The weight of 1 paperback is 0.6 pounds.
The weight of 1 textbook:
t = 5.1 - 2.5p
t = 5.1 - 2.5(0.6)
t = 3.6
The weight of 1 textbook is 3.6 pounds.

Explain the cosine rule and sine rule while also saying how to use it and provide examples (keep it in simple terms)
Answers
Answer:
Sure, I'll explain the cosine rule and sine rule in simple terms:
The cosine rule (also known as the law of cosines) is used to find the length of a side or the measure of an angle in a triangle given the lengths of the other sides and the angle between those sides. It states that c^2 = a^2 + b^2 - 2ab cos(C), where c is the length of the side opposite angle C, and a and b are the lengths of the other two sides.
Here's an example of how to use the cosine
Suppose we have a triangle with sides a=6, b=8, and an angle between them c=45 degrees. We want to find the length of the remaining side of the triangle, side a.
Using the cosine rule:
a^2 = b^2 + c^2 - 2bc * cosA
where A is the angle opposite side a, we can plug in our values and solve for a:
a^2 = 8^2 + 6^2 - 2(8)(6) * cos(45)
a^2 = 64 + 36 - 96 * 0.707
a^2 = 10.56
a = sqrt(10.56)
a = 3.25 (rounded to two decimal places)
Therefore, the length of side a is approximately 3.25 units.

We have: ∠APC + ∠BPC = 180⁰ (adjacent corner)
=> ∠APC + 133⁰ = 180⁰
=> ∠APC = 180⁰ - 133⁰ = 47⁰
Beside: x = ∠BPD = ∠APC = 47⁰ (opposite corner)
ANSWER: x = 47⁰
Ok done. Thank to me :3
The value of the angle x will be equal to 47⁰.
What is an angle?The angle is defined as the span between two intersecting lines or surfaces at or close to the point where they meet.
It is given that ∠APC + ∠BPC = 180⁰ (adjacent corner)
The angle x will be calculated as below:-
=> ∠APC + 133⁰ = 180⁰
=> ∠APC = 180⁰ - 133⁰ = 47⁰
Beside: x = ∠BPD = ∠APC = 47⁰ (opposite corner)
Therefore, the value of the angle x will be equal to 47⁰.
