This shows that all the sides of the triangle are given to be equal.
And the triangle whose all sides are equal is called equilateral triangle and in an equilateral triangle the measure of its each angle is 60°
⇒ ∠L = ∠N = ∠M = 60°
Now, ∠N = 60°
⇒ 7x - 3 = 60
⇒ 7x = 63
⇒ x = 9
Also, ∠M = 60°
⇒ 11y + 5 = 60
⇒ 11y = 55
⇒ y = 5
Answer: x=9

There were 67 candles on grandmas bBirthday cake and 26 left in the box how many candles birthda birthday cake and 26 left in the box how many candles were there in all
To find the total number of candles, you have to add the number of candles on your grandma's birthday cake, which are 67, to the number of candles left in the box, which are 26. This brings the total to 93 candles.
Explanation:The question involves a mathematical process known as addition. In this situation, you have 67 candles on your grandma's birthday cake and 26 more in a box. To find the total number of candles, you simply need to add the number of candles on the cake to the number of candles in the box.
So, 67 (candles on the cake) + 26 (candles in the box) = 93 candles in total. Hence, you have 93 candles in all.

Which biconditional statement is true?
A. A number is divisible by 9 if and only if it ends in 3.
B. A quadrilateral is a square if and only if it has four right angles.
C. The sum of two integers is positive if and only if the two integers are positive.
D. A number is an even number if and only if it is divisible by 2
Among the given options, the true biconditional statement is Option D: A number is an even number if and only if it is divisible by 2. This matches the true nature of a biconditional statement where both parts must have the same truth value.
The question posed is concerned with identifying the true biconditional statement among the given options. A biconditional statement is true if and only if both parts have the same truth value. We'll examine each option carefully.
Option A: A number is divisible by 9 if and only if it ends in 3. This statement is false because divisibility by 9 depends on the sum of the digits of the number, not just the last digit.Option B: A quadrilateral is a square if and only if it has four right angles. This statement is not entirely true because a rectangle also has four right angles but is not necessarily a square.Option C: The sum of two integers is positive if and only if the two integers are positive. This is false because the sum can also be positive if one integer is sufficiently larger than the negative of the other one.Option D: A number is an even number if and only if it is divisible by 2. This is a true biconditional statement. A number is considered even if it can be divided by 2 without leaving a remainder (with both having the same truth value).After reviewing the options, the correct answer is Option D.
A camera manufacturer spends $2,000 each day for overhead expenses plus $9 per camera for labor and materials. The cameras sell for $17 each. a. How many cameras must the company sell in one day to equal its daily costs? b. If the manufacturer can increase production by 50 cameras per day, what would their daily profit be?
250; $400
118; $656
170; $240
250; $850
17x = 2000+9x

x = 2000/8 = 250 cameras
250+50 = 300
17*50 = 850

The original price of the DVD is nine dollars the sale price is 80% of the price what is the sale price of the DVD?
multiply $9 by 80%
80% = 0.80
9 * 0.8 = 7.20
subtract that from original price
9 - 7.20 = 1.80
Sale price is $1.80
What are the roots of the quadratic equation 0 = 2x^2 + 12x –14?
2, 12, –14
–7, 1
–1, 7
1, 6, –7
Can you explain what it is wanting or asking?
Answer:
-7, 1
Step-by-step explanation:
Given quadratic equation,
[tex]2x^2+12x-14=0[/tex]
By middle term splitting,
[tex]2x^2+(14-2)x-14=0[/tex]
[tex]2x^2+14x-2x-14=0[/tex]
[tex]2x(x+7)-2(x+7)=0[/tex]
[tex](2x-2)(x+7)=0[/tex]
By the zero product property,
[tex]2x-2=0\text{ or }x+7=0[/tex]
[tex]\implies x=1\text{ or }x=-7[/tex]
Hence, the roots of the given equation are -7 and 1.

what is the true hourly wage of a job that pays $18 per hour and allows 20 hours of paid time off for every 500 hours worked ? show your work
The true hourly wage of a job is:
$ 18.72 per hour
Step-by-step explanation:The pay per hour is: $ 18
Also, it is given that: The job allows 20 hours of paid time off for every 500 hours worked.
This means he will be paid for 520 hours of work
but the true hourly wage will be calculated on the basis of 500 hours.
The wage for 520 hours of work will be: $ (18×520)= $ 9360
and the true hourly wage is:
Ratio of wage for 520 hours to 500 hours
i.e.
[tex]=\dfrac{9360}{500}\\\\\\=\dfrac{936}{50}\\\\=\$\ 18.72\ \text{per\ hour}[/tex]

Solve for n.
3(n+6)≥3n+8
no solution
all real numbers
n≥7
n≥23
Answer:
The correct option is B) all real numbers.
Step-by-step explanation:
Consider the provided inequity.
[tex]3(n+6)\geq 3n+8[/tex]
We need to solve the inequity for n.
[tex]3(n+6)\geq 3n+8[/tex]
[tex]3n+18\geq 3n+8[/tex]
Subtract 3n from both sides
[tex]3n-3n+18\geq 3n-3n+8[/tex]
[tex]18\geq 8[/tex]
Which is true for any real number. As 18 is greater than 8.
Hence, the value of n is all real numbers.
Thus the correct option is B) all real numbers.

Find the measure of an angle whose measure is 18 degrees less than one-half of the measure of its complement.Find the measure of an angle whose measure is 18 degrees less than one-half of the measure of its complement.
The measure of the angle in question is 18 degrees, as found by setting up an equation based on the relationship between an angle and its complement, and solving for the angle.
To find the measure of an angle that is 18 degrees less than one-half of the measure of its complement, first let's define the angle as x. Since the angle and its complement add up to 90 degrees, the complement is 90 - x. The given information tells us that x is 18 degrees less than half of its complement. Therefore, we can set up the equation:
x = (1/2)(90 - x) - 18
Doubling both sides gives:
2x = 90 - x - 36
Adding x to both sides and adding 36 to both sides gives:
3x = 54
Dividing by 3, we find that:
x = 18 degrees.
Therefore, the measure of the angle is 18 degrees.
