Answer:

Step-by-step explanation:
To calculate the value of x we must first understand the total value of all angles in a triangle.
Sum of all angles in a triangle = 180 degrees
That said, we need to write an equation for the total number of degrees in the triangle and solve for x
This will be as follows:
(13x+2)+(5x-7)+(3x-4)=180
The we combine the like terms. This will be as follows:
(13x+5x+3x)+(2-7-4)=180
Simplify further to get
21x-9=180
Simplify further by collecting all like terms on one side of the equal. This will entail the addition of 9 on each side of the equal sign as follows:
21x-9+9=180+9
you will find 21x=189
Simplify further by dividing both sides of the equal sign by 21 to solve for x
21x/21=189/21
Therefore x=9

Answer: 6
Step-by-step explanation: I think think the answer is 6 because if you cut 6 in half you get 3 and if cut 4 in half u get 2 the mutiply them...dont get mad if it wrong
Answer: A = 24 units^2
Step-by-step explanation: If you cut the shaded region in half it's two rectangles so you have to find the area of it using the formula to find the area of a rectangle.
A = (w)(l) A = (6)(4) A = 24 units^2

ABC and DEF are similar triangles. If the side lengths of ABC are 6, 8, and 12, and the
longest side of DEF is 18, then what are its other side lengths?
9 and 14
9 and 12
14 and 16
24 and 36
Applying the properties of similar triangles, the other side lengths of ΔDEF are: B. 9 and 12
Properties of Similar Triangles:
The ratio of the corresponding sides two triangles that are similar to each other are the same/equal.Given that ΔABC and ΔDEF are similar triangles, therefore:
Let, a = 6, b = 8, and c = 12 be the sides of ΔABC.Let, x, y, and z be the sides of ΔDEF.Let z = 18Thus:
a/x = b/y = c/z
Substitute6/x = 8/y = 12/18
Find x using 6/x = 12/18:
6/x = 12/18
Cross multiplyx = [tex]\frac{18 \times 6}{12}[/tex]
x = 9
Find x using 8/y = 12/18:
8/y = 12/18
Cross multiplyx = [tex]\frac{18 \times 8}{12}[/tex]
x = 12
Therefore, applying the properties of similar triangles, the other side lengths of ΔDEF are: B. 9 and 12

The sides forming the right angles and hypotenuse of a right angled triangle are x cm, (2x + 2) cm and (3x – 2) cm respectively. Calculate the perimeter of the triangle.
Answer:
6x
Step-by-step explanation:
Perimeter is the sum of all the sides:
(x) + (2x + 2) + (3x - 2)
Add like-terms:
6x + 2 - 2 = 6x
Perimeter = 6x

What is the slope of the line whose equation is 12=4x−6y?
Please and thanks if you decide to answer.
Answer:
slope =4
Step-by-step explanation:
from, y=mx + c
where m is slope
Answer:
the slope formula is y=mx+b where b is the y intercept and m is the slope we rewrite the equation by subtracting 4x from either side and then dividing both sides by 6 so we have y=-0.6x+2 so m the slope is -0.6

What does the rational form of the ratio a:b look like?
The rational form of a ratio is the ratio represented as a fraction (or quotient)
The rational form of the ratio a : b is a/b
The ratio is given as a : b (pronounced a ratio b)
This is properly represented as:
[tex]\mathbf{Ratio = a : b}[/tex]
To convert to rational form, means that we express the ratio as a fraction.
So, the ratio becomes
[tex]\mathbf{Ratio = \frac a b}[/tex] (pronounced a divided by b)
Hence, the rational form of the ratio a : b is a/b

Hello! My name is Galaxy and I will be helping you today. I hope you are having a nice day.
We can solve this problem in one single step, I'll start off with that.
We can first figure out what it says and make an algebraic equation. We can see what language the question uses and elaborate on that to create our equation.
[tex]5x-5<6x+2[/tex]
We can use algebra to simplify the equation so that we can solve for it.
[tex]-5<x+2\\-7<x\\x>-7[/tex]
We can check if this is correct by testing a few numbers from that range, I'll take -5 and 2.
[tex]5(2)-5<6(2)+2?\\10-5<12+2?\\5<14[/tex]
We've proven that 2 is working.
[tex]5(-5)-5<5(-5)+2?\\-25-5<-25+2?\\-30<-23[/tex]
We've also proven that -5 works.
We can now say that we've solved the problem, the solution of the problem would be x>-7.

Answer:
418.6
Step-by-step explanation:
you set the price to equal 300 dollars, so marking up 40% would equal taking 300 x 1.4
this equals 420, however you need to substract 1.4 because you rounded 299 to 300 giving 418.6

299 ×40%=119.6
so the final price is 299+119.6=418.6
