log(3x) = log(2x-4)

taking antilog of both sides:

3x = 2x - 4

3x - 2x = -4 [subtracting 2x from both sides]

x = -4

and we're done already!

Express the ratio in the simplest form. 20 gallons to 0.75 gallons

expeople1 [14]

ANSWER

The ratio in the simplified form is

80:3

EXPLANATION

We want to express 20 gallons to 0.75 gallons as a ratio in its simplest form.

We obtain the ratio as follows:

$20:0.75$

This is the same as

$20: \frac{3}{4}$

We multiply each term in the ratio by 4 to obtain;

$20 \times 4:0.75 \times 4$

This gives us,

$80:3$

Answer:

1.8 ; 11.8 ; 4.18

Step-by-step explanation:

Given the data:

X : 2.4,1.6, 3.2,0.3, 1.5

Mean, m = Σx / n

Σx = 9 ; n = 5

m = 9 /5

m = 1.8

If data is increased by 10:

X : 12.4, 11.6, 13.2, 10.3, 11.5

Σx = 59 ; n = 5

m = 59 /5

m = 11.8

If data values is doubled :

X : 5.76, 2.56, 10.24, 0.09, 2.25

Σx = 20.9 ; n = 5

m = 20.9 /5

m = 4.18
