Answer:
x ≈ 2.55
Step-by-step explanation:
Since the triangles are congruent then DE ≡ AB , that is
DE = AB
76x - 7 = x + 184 ( subtract x from both sides )
75x - 7 = 184 ( add 7 to both sides )
75x = 191 ( divide both sides by 75 )
x ≈ 2.55 ( to the nearest hundredth )
Angle 3 is equal to angle
Find m<YQR pls need grade gud.
Answer:
21°
Step-by-step explanation:
We can prove these two triangles congruent by the HL (Hypotenuse-Leg) theorem. Then, we know that m<YQR is congruent to m<PQY. We can then use their given values to form an equation.
5x+6=16x-27
Continue to solve . . .
33 = 11x
x=3
Therefore, we can plug this value of 3 into the expression for the value of m<YQR, and you will get
(16 x 3) - 27, which is equal to 21°.

Step-by-step explanation:
Write 14/square root of 2 + square root of 50 in the form b square root of 2 where b is an integer
Step-by-step explanation:
[tex] \frac{14}{ \sqrt{2} } + \sqrt{50} \\ \frac{ \sqrt{2} \times \sqrt{2} \times 7}{ \sqrt{2} } + \sqrt{25 \times 2} \\ \\ 7 \sqrt{2} + 5 \sqrt{2} = 12 \sqrt{2} [/tex]
The given expression can be written in the form of b√2 as 12√2 where b = 12.
What is an Algebraic expression?An algebraic expression can be obtained by doing mathematical operations on the variable and constant terms.
The variable part of an algebraic expression can never be added or subtracted from the constant part.
The given expression is [tex]14/\sqrt{2}+\sqrt{50}[/tex].
It can be rewritten as,
[tex]14/\sqrt{2}+\sqrt{50}[/tex]
Multiply √2 to both numerator and denominator of 14/√2 as,
14√2/2 + √50
⇒ 7√2 + √(5 × 5 × 2)
⇒ 7√2 + 5√2 = 12√2
On comparing 12√2 with b√2, it is obtained as,
b = 12
Hence, the given expression can be written as 12√2.

Work out the perimeter of a regular octagon with side length 2.6mm
Answer:
20.8mm
Step-by-step explanation:
We know that an octagon has 8 sides, and since this is a regular octagon we can safely say that all sides are equal.
This means all sides are 2.6mm.
So if we run the calculation:
2.6mm × 8 = 20.8mm (Side Length × Number of Sides = Perimeter)
We have our final answer!
Why is 40x-16 not equivalent?
Please help (i’m in 7th grade)
Answer:
40x-6 is not equivalent because 16 is not a multiple of 40
Step-by-step explanation:
if you write the multiples of 4o you will see that 16 is not one of them so that means 40x-16 is not equivalent

Devon has been saving $5 & $10 for the past four years. Over spring break he wanted to see how much money he has saved up. After counting the money he calculated that he has a total of $395 & had 49 bills. Based on this information, how many $5 & $10 bills does he have?
Answer:
19 five dollar bills
30 ten dollar bills
Step-by-step explanation:
x=number of $5 bills
y=number of $10 bills
x+y=49
x=49-y
5x+10y=395
substitute for x
5(49-y)+10y=395
245-5y+10y=395
245+5y-245=395-245
5y=150
5y/5=150/5
y=30
x=49-30=19

2. Which equation is equivalent to 2 + 4x = 5 - 3(x + 1)? A. 2 + 4x = 2x - 3 B. 2 + 4% = 5 - 3 -3. C. 6x = 5-(+ 1). D. 2 + 4 = 2/5 1).
Answer:
B) 2 + 4x = 5 - 3 - 3x
Step-by-step explanation:
By simplifying JUST the right side and re-arranging them
2 + 4x = 5 - 3(x + 1),
2 + 4x = 5 - 3x -3,
2 + 4x = 5 -3 - 3x

Describe how you know whether an equation will be true for all values of x or true for no values of x.
Answer:
Substitute your answer for the variable x. If the equation looks accurate or is correct, then the value of x is the right answer. Not sure if this makes sense
Determining whether an equation is true for all values of x or true for no values of x requires simplifying the equation, determining its domain, checking for variable restrictions, and evaluating the equation for different values of x.
What is an equation?The equation is defined as mathematical statements that have a minimum of two terms containing variables or numbers that are equal.
Simplify the equation as much as possible using algebraic manipulations such as combining like terms, factoring, and expanding.
Evaluate the equation for a few different values of x to see if it holds true. If the equation is true for all values of x within the domain, then it will be true for all values of x. If there are any values of x within the domain that make the equation false, then it will be false for no values of x.
If the equation cannot be simplified or the domain cannot be determined, then it may require further analysis, such as graphing or using calculus techniques to determine its behavior.
Thus, determining whether an equation is true for all values of x or true for no values of x requires simplifying the equation, determining its domain, checking for variable restrictions, and evaluating the equation for different values of x.

what is the answer for this
Answer:
∠B = 141
Step-by-step explanation:
n - > number of sides
n = 7
Sum of all interior angles = (n -2 ) * 180
= 5 * 180 = 900
∠B + 148 + 90 + 142 + 130 + 129 + 120 = 900
∠B + 759 = 900
∠B = 900 - 759 = 141

1) 2/5 x 3 =?
Since we cannot possibly cancel the denominators, let us multiply 2 and 3.
Answer will become, 6/5.
2) 2/3x3 =?
We can cut 3 and 3.
Answer will become, 2.
3) 2/5 x 3=?
This is a repeated question and the answer remains the same as the 1st question's answer, 6/5.
4) 3/2 x 3=?
We cannot cancel the denominators, let us multiply 2 and 3.
