Answer:

1:5

Step-by-step explanation:

find the LCF

multiples of 20: 1, 2, 4, 5, 10, 20

multiples of 4: 1, 2 4

the lcf is 4

20 ÷ 4=

4 ÷ 4=

the original ratio would be 4:20

divide by 4

1:5

Answer:

Step-by-step explanation:

Equation

3x + 9 + 2x = x - 2x - 3

Solution

Combine all the like terms.

3x+2x+9 = x - 2x - 3

5x + 9 = -x - 3 Add x to both sides of the equation

5x+x +9 = -x+x -3 Combine

6x + 9 = - 3 Subtract 9 from both sides of the equation

6x+9-9 = - 3-9 Combine

6x = -12 Divide both sides by 6

6x/6 = -12/6

x = - 2

Answer x = - 2

Answer it pls option c

Troyanec [42]

Answer:

$x = \frac{1}{4}$

Step-by-step explanation:

$\frac{x}{2} +\frac{3}{4} =\frac{7}{8}$

→ Find the LCM of the denominators (2,4 and 8)

LCM = 8

→ Multiply the whole equation by 8 to get rid of the fractions

4x + 6 = 7

→ Minus 6 from both sides to isolate 4x

4x = 1

→ Divide both sides by 4 to isolate x

$x = \frac{1}{4}$

Which of the following is 38/6 converted to a mixed number

Monica [59]

6 goes into 38 6 times (6 * 6 = 36). We can bring out a whole number of 6 into our mixed number. Now, we have 2/6 left over. That can be reduced to 1/3. Your mixed number is $6\frac{1}{3}$

Establish for which constants c the following function is a density.

Valentin [98]

By "density" I assume you mean "probability density function". For this to be the case for $f(x)$ , we require

$\displaystyle\int_{-\infty}^\infty f(x)\,\mathrm dx=1$

Since

$f(x)=\begin{cases}cx^{1/2}&\text{for }0$

you have

$\displaystyle\int_{-\infty}^\infty f(x)\,\mathrm dx=\int_0^2cx^{1/2}\,\mathrm dx=\dfrac{2c}3x^{3/2}\bigg|_{x=0}^{x=2}=\dfrac{2^{5/2}c}3=1$

which means

$c=\dfrac3{2^{5/2}}=\dfrac3{4\sqrt2}$

Least to greatest 2/9, 21%, 0.21, 11/50

miv72 [106K]

2/9=22%
21%
21%
22%

So it would be 21%, 0.21, 11/50, 2/9.
