Find the value of x

Answer:

Step-by-step explanation:

21(5m - 3) = 63*9

105m - 63 = 567

105m = 630

m = 6

Answer:

2/21

Step-by-step explanation:

5m=9/21+3/63

5m=27/63+3/63

5m=30/63

5m=10/21

m=10/21/5

m=10/21 x 1/5

m=2/21

Answer:

Step-by-step explanation:

In the given arithmetic series,

To find the sum of the series, we need to find the number of terms (n) at first. So,

[tex]a_{n} = a + (n - 1)d\\38 = 6 + (n - 1) 4\\38 - 6 = 4n - 4\\32 = 4n - 4\\32 + 4 = 4n\\36 = 4n\\36 \div 4 = n\\\boxed{9 = n}[/tex]

Now, let's find the sum of the arithmetic series (Sₙ).

[tex]S_{n} = \frac{n}{2} [2a + (n - 1)d]\\S_{n} = \frac{9}{2} [2*6 + (9 -1)4]\\S_{n} = \frac{9}{2} [12+ (8*4)]\\S_{n} = \frac{9}{2} [12+ 32]\\S_{n} = \frac{9}{2} (44)\\S_{n} = 9*22\\\boxed{S_{n} = 198}[/tex]

Answer:

8 possible outcomes

Step-by-step explanation:

I'm going to list all the possibilities and then count them up.

First Word is the wallpaper color, Second is the carpet color.

Red + Purple, Red + Yellow, Blue + Purple, Blue + Yellow, Yellow + Purple, Yellow + Yellow, Green + Purple, Green + Yellow

After counting them up, we get 8. Therefore there are 8 possible outcomes.

Another way is to multiply the possible outcomes for each event together, and you can get the total number of outcomes. For example, in this problem there is 4 wallpaper colors and 2 carpet colors, so when u multiply them u get 8 total outcomes. Hope this helped!

Step-by-step explanation:

gradient=vertical /horizontal

g=V/H

g= -8/6

g=-1.3

The given temperatures of 70 °F, 50 °F, and 35 °F, at the given 3, 3, and

6 days give the following step function;

[tex]\begin{cases}f(x) = 70^{\circ } & \text{ if } 0 \leq x \leq 3 \\f(x) = 50^{\circ} & \text{ if } 3 < x \leq 6 \\ f(x) = 35^{\circ }& \text{ if } 6 < x \leq 12 \end{cases}[/tex]

The temperature at it is fermented in the first three days = 70 °F

From day 3 to 6 the temperature = 50 °F

From day 6 to day 12, the temperature at which it is kept in the freezer = 35 °F

The step function is therefore;

[tex]\begin{cases}f(x) = 70^{\circ } & \text{ if } 0 \leq x \leq 3 \\f(x) = 50^{\circ} & \text{ if } 3 < x \leq 6 \\ f(x) = 35^{\circ }& \text{ if } 6 < x \leq 12 \end{cases}[/tex]

Answer: A. 57 degrees

Step-by-step explanation:

If it's a right triangle, that means one of the angles is 90 degrees.

The sum of the angles in a triangle is 180 degrees.

We are given the other angle's measure as 33 degrees.

Therefore the other angle's measure is 180-90-33 = 57 degrees

Answer:

T(n) = 7+n

Step-by-step explanation:

A.P. Formula: a(n) = a + (n-1)d

Since a = 8 (given),

and we know 2*[T(8)] = T(16)

We may set up an equation to find d/

2(8+(8-1)d) = 8+(16-1)d

d = 1

Therefore, T(n) = 8 + (n-1)(1) = 7+n

Step-by-step explanation:

If we find a common denominator for both fractions we can find the answer. 6 and 8 both go into 24 so,

5/6 x 4/4 = 20/24

5/8 x 3/3 = 15/24

Answer:

First, let's just pick an arbitrary number as an example 7.031.

the 1 is in the thousandth place, so we can represent this as [tex]7\frac{31}{1000}[/tex].

This is so because determining what denominator of a decimal number is can be known through what non-zero digits is on the right-most side of the number.

Step-by-step explanation:

Answer:

The third digit after a decimal point is in the "thousandth" place.

Therefore, to convert a decimal that terminates after three decimal places to a fraction, simply write the digits (without leading zeros) as the numerator and 1000 as the denominator.

For example:

[tex]12.345=\dfrac{12345}{1000}[/tex]

[tex]0.932=\dfrac{932}{1000}[/tex]

Answer:

6. [tex]y=2(0.3)^x[/tex]

7. 3, greater than 1, growth, (0,3)

Step-by-step explanation:

General form of an exponential equation:  [tex]y=ab^x[/tex]

(where a is the initial value, b is the growth/decay factor, and x is the independent variable)

If b > 1, the function represents exponential growth.

If 0 < b < 1, the function represents exponential decay.

Therefore, [tex]y=2(0.3)^x[/tex] represents an exponential decay (as 0 < b < 1)

For [tex]y=3(4)^x[/tex]

The y-intercept is when x = 0 ⇒ [tex]y=3(4)^0=3[/tex]

The value of a is 3.  The value of b is greater than 1.  So, the function represents exponential growth.  The y-intercept is (0, 3)

Answer:

x = 7

Step-by-step explanation:

5x - 1 + 8x + 5 = 95

Triangle in 95° so x is

»8x + 5° + 5x - 1° = 95°

»13x + 4° = 95°

»x = 91°/13

»x = 7°✅

Answer:

A. x = 212

Step-by-step explanation:

      This scale is showing us that x + 122 is equal to 334 because the scale is balanced and we can see an equal sign (=) in the center. We will set up an equation and solve for x.

[Equation]

x + 122 = 334

[Subtract 122 from both sides]

x = 212

A. x = 212
