Solve for x 8x + 12 = 2x - 18
Answer:
[tex] \sf \Large x=−5 [/tex]
Step-by-step explanation:
Let's solve your equation step-by-step.
8x+12=2x−18
Step 1: Subtract 2x from both sides.
8x+12−2x=2x−18−2x
6x+12=−18
Step 2: Subtract 12 from both sides.
6x+12−12=−18−12
6x=−30
Step 3: Divide both sides by 6.
6x/6 = −30/6
x=−5
Step-by-step explanation:
8x + 12 = 2x -18
8x - 2x = -18 - 12
6x = -30
6x/6 = -30÷6
x = - 5

2. Erica Matthews is married and earns $54,730 per year as a grant writer. Her state's tax rate is 3.5% of
taxable income.
If the income is $54730 and state tax rate is 3.5% then the amount of tax that Erica Matthews needs to pay is $1915.55.
Given that the income is $54730 and state tax rate is 3.5%.
We are required to find the amount of tax that Erica Matthews need to pay.
State Government is basically tax that is levied by state government on the people living in that state.State governments basically use taxpayer dollars to fund road maintenance, law enforcement agencies and other public services.
Income=$54730
Tax rate=3.5%
Tax=54730*3.5/100 (We assumed that full amount is taxable.)
=$1915.55
Hence if the income is $54730 and state tax rate is 3.5% then the amount of tax that Erica Matthews needs to pay is $1915.55.

A dealer made a profit of 22.5% by selling a car for GH¢5,880. Find the percentage profit he would have realized if he had sold it for GH¢6,120.
The percentage of profit would be $1,377 if the dealer would have sold the car for $6,120.
What do we mean by percentages?A percentage is a number or ratio expressed as a fraction of 100 in mathematics. It is frequently denoted by the percent sign, "%."One percent (symbolized 1%) is the one-hundredth part; thus, 100 percent represents the entire amount and 200 percent specifies twice the given amount. For example, 1% of 1,000 chickens equals 1/100 of 1,000, or 10 chickens; 20% of the quantity equals 20/100 1,000, or 200 chickens.So, we need to obtain 22.5% of $6,120.
Then,
$6,120/100 × 22.561.2 × 22.51,377Therefore, the percentage of profit would be $1,377 if the dealer would have sold the car for $6,120.

solve each system of equations by elimination
Answer:
x = [tex]\frac{16}{41}[/tex]
y =[tex]\frac{102}{41}[/tex]
Step-by-step explanation:
To use elimination I need either the x terms to be inverses of each other or the y terms to be inverses of each other. There are a number of ways to do this. I am going to focus on the y's. If I multiple the first equation through by 5 and the second equation through by 3. I will make equivalent equations that will allow the y terms to be eliminated.
14x - 3y = -2
5(14x - 3y) =5(-2)
70x - 15y = -10
4x + 5y = 14
3(4x + 5y) = 3(14)
12x +15y =42
Add together the 2 bold equations above
70x - 15y = -10
12x + 15y = 42
82x = 32 Divide both sides by 82
x = [tex]\frac{32}{82}[/tex] = [tex]\frac{16}{41}[/tex]

Which sequence of transformations can joseph perform to show that figure A and figure B are congruent
Step-by-step explanation:
If rigid transformations can be used to map two shapes onto one another, they are said to be congruent (a sequence of one or more rotations, translations, and reflections). Any series of rigid transformations performed on a triangle results in a congruent triangle.
Let's now analyze rigid transformation.
An isometry, also known as a rigid transformation of the plane, preserves length. Reflections, translations, rotations, and combinations of these three transformations are all considered "rigid transformations".

The area of the polygon is equal to 10.006 square units.
How to determine the area of a polygon
In this case we find a polygon with four vertices, that is, a tetragon, also called quadrilateral. By geometry we know that quadrilaterals can be armed by uniting two triangles and the area of a quadrilateral is equal to the areas of the two triangles. Hence, the polygon NPQR is the result of combining the triangles NPQ and NQR.
First, determine the lengths of the sides of the two triangles:
NP = √[[3 - (- 2)]² + (1 - 1)²]
NP = 5
PQ = √[(3 - 3)² + [1 - (- 1)]²]
PQ = 2
NQ = √[[3 - (- 2)]² + (- 1 - 1)²]
NQ = √29
NR = √[[- 2 - (- 2)]² + [- 1 - (- 1)]²]
NR = 2
QR = √[(- 2 - 3)² + [(- 1) - (- 1)]²]
QR = 5
Second, calculate the areas of the two triangle:
s₁ = 0.5 · (NP + PQ + NQ)
s₁ = 0.5 · (5 + 2 + √29)
s₁ ≈ 6.193
A₁ = √[s₁ · (s₁ - NP) · (s₁ - PQ) · (s₁ - NQ)]
A₁ = √[6.193 · (6.193 - 5) · (6.193 - 2) · (6.193 - √29)]
A₁ ≈ 5.003
s₂ = 0.5 · (NQ + NR + QR)
s₂ = 0.5 · (√29 + 2 + 5)
s₂ ≈ 6.193
A₂ = √[s₂ · (s₂ - NQ) · (s₂ - PQ) · (s₂ - QR)]
A₂ = √[6.193 · (6.193 - √29) · (6.193 - 2) · (6.193 - 5)]
A₂ ≈ 5.003
A = 5.003 + 5.003
A = 10.006

Can a table 9 feet wide (legs folded) fit through a rectangular doorway 4 feet by 8
Yes , it is possible to fit a table 9 feet wide through a rectangular doorway 4 feet by 8.
The Pythagorean theorem states, "In a right triangle, the square of the hypotenuse equals the sum of the squares of the other two sides." The sides of this triangle were called the perpendicular, the base, and the hypotenuse. Here, the hypotenuse is on the opposite side of the 90° angle, so it is the longest side. The sides of a right triangle (a, b, c, etc.) with positive integer squared values are put into the equation, also known as the Pythagorean triple. which is given by [tex]c^2=a^2+b^2[/tex] here “a” is the perpendicular, “b” is the base, “c” is the hypotenuse.A table with folded legs can pass through a rectangular door at an angle of 45°, forming a triangle to which the Pythagorean theorem can be applied.
Let the two sides of the door be the two sides of triangles a and b, then
[tex]c^2=4^2+8^2\\c^2=16+64\\c^2=80\\c=8.94[/tex]
Conclusion: Using the Pythagorean theorem, we know that an 8.94 foot table can pass through the door. And we know that 8.94 ≈ 9
