Answer:

x = 15

Step-by-step explanation:

<JKM is the sum of the two smaller angles.

<JKL + <LKM = <JKM

<JKM = 154

<JKL  = 6x

<LKM = 3x + 19

6x + 3x + 19 = 154             Subtract 19 from both sides

9x + 19 - 19 = 154-19         Combine            

9x = 135                            Divide by 9

9x/9 = 135/9

x = 15

Answer:

37

Step-by-step explanation:

The two angels are congruent, meaning they're the same. So its just what multiplied by 2 gets 74. So 74 divided by 2 is 37.

I hope I could help. Enjoy your day! Maybe brainiest if this was right?

No pressure! :)

Answer:

37

Step-by-step explanation:

This is a vertical angle, meaning 74 and 2x would be equivalent to each other. So we have to make 2x equal to 74. We set up an equation, 2x = 74. Divide 2 for both sides; 74 divided by 2 = 37; 2x divided by 2 (2 cancels out, leaving x alone). Therefore, x = 37.

To check, substitute x with 37. 37 times 2 is 74, and since the left is 74 the right also have to be 74.

Answer:

n = 10

Step-by-step explanation:

Using the rule of exponents

• [tex]a^{m}[/tex] × [tex]a^{n}[/tex] = [tex]a^{(m+n)}[/tex]

• [tex](a^m)^{n}[/tex] = [tex]a^{mn}[/tex]

Then

2² × [tex]2^{n}[/tex] = [tex](2^4)^{3}[/tex]

[tex]2^{2+n}[/tex] = [tex]2^{12}[/tex]

Since the bases on both sides are equal, both 2 then equate exponents

2 + n = 12 ( subtract 2 from both sides )

n = 10

Answer:

The least number should 4851 be divided to get a perfect square number = 11

The square root of the obtained perfect square number is 21

Step-by-step explanation:

Given number = 4851

It can be written as

4851 = 3×1617

4851 = 3×3×539

4851 = 3×3×7×77

4851 = 3×3×7×7×11

4851 = (3×3)×(7×7)×11

It is clear that We should divide the given number by 11 then we get a perfect square number.

4851/11 = 441

441 = 21×21

=> 441 = 21²

=> √441 = √(21²)

=> √441 = 21

The least number should 4851 be divided to get a perfect square number = 11

The square root of the obtained perfect square number is 21

→ Prime Factorization Method

Answer:

11 is the least number and the when you take the square root of the number you get 21

Step-by-step explanation:

The easiest way to solve this problem is guess and check.

First of all, a perfect square NEEDS to be a WHOLE number

Since 4851 is odd, you cannot divide it by an even number evenly, as it would result in a number with a remainder or leftover decimal amount.

This means you cannot divide by 2, 4,8...etc

We just have to guess and check odd numbers starting at 3.

4581/ 3 = 1527                 sqrt(1527) = 39.07684737    decimal so not this one

4581/ 5 = 916.2               decimal so not this one

4581/ 7 = 654.4285714  decimal so not this one

4581/ 9 = 509                 sqrt(509) = 22.56102835     decimal so not this one

4581/ 11 = 441                  sqrt(441) = 21

This is the first instance where 4581 is divisible by a number that yields a perfect square, so 11 is the least number and the square root of the result is 21.

Answer:

Disciminant of f = 0

x-intecept = [tex](\frac{3}{2}, 0)[/tex]

Step-by-step explanation:

Given the quadratic function, -4x² + 12x - 9

where a = -4, b = 12, and c = -9

The discriminant, b²- 4ac, is the expression inside the radical (numerator) of the quadratic formula:

[tex]x = \frac{-b +/- \sqrt{b^{2}-4ac} }{2a}[/tex]

The first part of your given problem asks for the discriminant. Substitute the values for a, b, and c:

b²- 4ac = 12² - 4(-4)(-9) = 144 - 144 = 0  → This implies that the quadratic function has one real root.

Therefore, the disciminant of f is 0.

Next, the given problem asks for the x-intercepts. The x-intercept is the point on the graph where it crosses the x-axis. As I mentioned earlier, the function has one real root. Therefore, it means that there is only 1 x-intercept.  To find out what the x-intercept is, use the quadratic formula:

[tex]x = \frac{-b +/- \sqrt{b^{2}-4ac} }{2a}[/tex]

[tex]x = \frac{-12 +/- \sqrt{12^{2}-4(-4)(-9)} }{2(-4)}[/tex]

[tex]x = \frac{-12 +/- \sqrt{144 - 144} }{-8}[/tex]

[tex]x = \frac{-12}{-8} = \frac{3}{2}[/tex]

Therefore, the x-intercept is [tex](\frac{3}{2}, 0)[/tex].  

Answer:

x = -3

Step-by-step explanation:

Given the equation,  -4(10 + 3x) - (x + 8) = - 9:

Distribute -4 into (10x + 3x), and - 1 into (x + 8):

-4(10 + 3x) - (x + 8) = - 9

-40 -12x - x - 8 = -9

Combine like terms:

-48 - 13x = -9

Add 48 to both sides:

-48 + 48 - 13x = -9 + 48

-13x = 39

Divide both sides by -13:

[tex]\frac{-13x}{-13} = \frac{39}{-13}[/tex]

x = -3

Therefore, x = -3

Answer: The simplest form of this equation is 16q-12

Step-by-step explanation:

Answer:

(-7q+1) + (9q-13)

2q - 12

Step-by-step explanation:

The first step you'll take is to combine like terms:

-7q + 1 + 9q - 13 ⬇

-7q + 9q + 1- 13

It will be 381. You round up if it is five and over, and round down if 5 and below.

Step-by-step explanation:

A decimal cannot be a whole number so rounding to the nearest whole number means getting rid of the decimal. You do this by rounding up if it 5 and up, and rounding down if it is 5 and below. 380.5 means you would round up to 381. If it it were 380.4, you would round down to 380.

Step-by-step explanation: 1/2x=16

16x4=64, Although this is not exactly 55 cookies, you can either make more or less. So you need 4 salt, to make 55.

Answer:

[tex]\frac{55}{32}[/tex] tsp

Step-by-step explanation:

To find out how much salt you would need to make 55 cookies, you need to find how much salt makes 1 cookie:

If [tex]\frac{1}{2}[/tex] tsp of salt makes 16 cookies, then ([tex]\frac{1}{2}[/tex] ÷ 16) tsp of salt will make 1 cookie.

But how much is [tex]\frac{1}{2}[/tex] ÷ 16?

To divide fractions with different denominators easily, use the SFM method:

S - Skip

F - Flip

M - Multiply

[tex]\frac{1}{2}[/tex] ÷ [tex]\frac{16}{1}[/tex]      First, Skip your focus to the 2nd number. This is what will be changed.

[tex]\frac{1}{2}[/tex] ÷ [tex]\frac{1}{16}[/tex]      Next, Flip the numerator and denominator.

[tex]\frac{1}{2}[/tex] × [tex]\frac{1}{16}[/tex]      Finally, multiply the two numbers together.

[tex]\frac{1}{32}[/tex]

[tex]\frac{1}{32}[/tex] tsp of salt will make 1 cookie.

Now to find the amount needed for 55 cookies:

To find the amount of salt needed to make 55 cookies, multiply [tex]\frac{1}{32}[/tex] × 55.

[tex]\frac{1}{32}[/tex] × [tex]\frac{55}{1}[/tex] = [tex]\frac{55}{32}[/tex]

Because the fraction cannot be simplified further, the amount of salt that is needed to make 55 cookies is [tex]\frac{55}{32}[/tex] tsp.

Answer:

43/40 or 1 3/40

Step-by-step explanation:

9/10 - (1/8 - 3/10)

Remember, we have to solve what's in the parentheses first!

To find 1/8 - 3/10, we must find the least common multiple of the denominators, which is 8 and 10.

Let's list the multiples of 8 and 10

Multiples of 8: 8, 16, 24, 32, 40, 48, 56...

Multiples of 10: 10, 20, 30, 40, 50, 60...

We found a match! 40 is a multiple of both 8 and 10, so we can use that.

To make the denominator 40 for 1/8, we have to multiply both the numerator and denominator by the same number, and the denominator must equal 40 after.

So,

8 times what equals 40?

To make it easier, we can do 40 / 8, which is 5.

That means we multiply the denominator and numerator by 5, so we get 5/40 - 3/10.

If you do the same thing for 3/10, you get 12/40.

Our equation is much easier!

We can easily do 5/40 - 12/40, which is -7/40.

Now, we do 9/10 - (-7/40)

Remember, two minuses right next to each other make a plus!

Our equation is now 9/10 + 7/40.

If you do the least common multiple for 9/10, you get 36/40.

Finally, we do 36/40 + 7/40, which is 43/40.

If it's asking for a mixed number, it would be 1 3/40.

Therefore, 9/10 - (1/8 - 3/10) equals 43/40 or 1 3/40!

The composite function m(n(x)) is 70x²+ 19

Given the functions

m(x)=10x−9

n(x)=7x²+4

We need to get the composite function m(n(x))

m(n(x)) = m(7x²+4)

To get m(7x²+4), we need to replace x as 7x²+4 in function m(x) as shown:

m(7x²+4) = 10(7x²+4) - 9

m(7x²+4) = 70x²+ 28 - 9

m(7x²+4) =  70x²+ 19

Hence the composite function m(n(x)) is 70x²+ 19
