Answer:

32

Step-by-step explanation:

first angle is 20, let third angle be x, therefore second angle equals 4x;  angle in a triangle is 180, so 4x+x+20=180;   5x=160;   x=32

Answer:

- 3

Step-by-step explanation:

2x - 9 = 5x

- 9 = 5x - 2x

-9 = 3x

-9/3 = x

x = -3

Answer:

3.25

Step-by-step explanation:

Perimeter of triangle = 3(5) = 15 cm

Perimeter of rectangle = 2(2x - 3 + 4)

Perimeter = 2(2x + 1)

Perimeter = 4x + 2

4x + 2 = 15

4x = 15 - 2

4x = 13

x = 13/4

x = 3.25

Answer:

x = 1/2

Step by step explanation:

Two numbers a and b are each greater than zero.

i.e a > 0 and b > 0

And;

[tex] \sqrt{a} \: = \: \sqrt[3]{b} [/tex]

Since the square root of a is equal to cube root of b then,

a = b = 1

[tex] {a}^{2x \: - \: 1} \: = \: b[/tex]

[tex] {1}^{2x \: - \: 1} = {1}^{0} [/tex]

2x - 1 = 0

x = 1/2

Two numbers are 'a' and 'b'.

And a > 0, b > 0

[tex]\sqrt{a}=\sqrt[3]{b}[/tex]

[tex]a^{\frac{1}{2} }=b^{\frac{1}{3}}[/tex]

[tex]a=(b)^{\frac{2}{3} }[/tex]

We have to find the value of [tex]x[/tex] if [tex]a^{2x-1}=b[/tex],

By substituting the value of [tex]a[/tex] in the given expression,

[tex](b^{\frac{2}{3}})^{2x-1}=b[/tex]

Now use the laws of exponents,

[tex]b^{\frac{2}{3}(2x-1)}=b[/tex] [Since, [tex](a^m)^n= a^{mn}[/tex]]

By comparing the exponents on both the sides,

[tex]\frac{2}{3}(2x-1)=1[/tex]

[tex]2(2x-1)=3[/tex]

[tex]4x-2=3[/tex]

[tex]4x=5[/tex]

[tex]x=\frac{5}{4}[/tex]

[tex]x=1.25[/tex]

Answer:

Step-by-step explanation:

We need to find the LCM of 12 and 9.

Their LCM is:

Number of light fixtures and light bulbs is 36.

Number of packages will be:

Step-by-step explanation:

First finding LCM of 9 and 12

9 = 3 × 3

12 = 2 × 2 × 3

LCM = 3 × 2 × 2 × 3

LCM = 36

Now,

No. of light fixtures = 36/12 = 3

No. of light bulb = 48/12 = 4

Answer: 10h^2

Step-by-step explanation:

You’re gonna wanna combine your like terms, so…

([6h^2 + 8h^2] - 4h^2)

(14h^2 - 4h^2 = 10h^2)

So your answer would be: 10h^2

Answer:

The coefficient of x is 1.

Step-by-step explanation:

If the question had asked for the coefficient of x^2 then it would be 3.

The coefficient of a variable is the number that is attached to it (the big number, not the exponent).

Answer and Step-by-step explanation:

To find the length of PQ, we need to set the length of PQ equal to the length of QR (since in the question it tells us that PQ is equal to QR).

PQ = QR

x + 1 = 12

Solve for x.

Subtract 1 from both sides of the equation.

x + 1 - 1 = 12 - 1

x = 11

Now plug this number into the expression length for PQ.

11 + 1 = 12

The length of PQ is 12.

(you can also see that QR has a length of 12, so we can just say that PQ 12).

Answer:

  27

Step-by-step explanation:

Evaluating this expression according to the order of operations is a straightforward calculator problem.

  = (81 ÷ 27)³ = 3³ = 27

__

You can also use the rules of exponents to simplify this before evaluating.

  (a^b)^c = a^(bc)

  (a^b)/(a^c) = a^(b-c)

__

  = ((3²)² ÷ 3³)³ = (3⁴ ÷ 3³)³ = (3¹)³ = 3³ = 27

Answer: B = 5

Step-by-step explanation:

Point A = (2,2) and point B = (6,5)

Distance between 2 points = sqrt [ (x-x)^2 + (y-y)^2]

Sqrt [(6-2)^2 + (5-2)^2]

Sqrt (4^2 + 3^2)

Sqrt (16 + 9) = sqrt 25 = 5
