Solve this equation 3(2x+3)=9

Scilla [17]

Answer:

Step-by-step explanation:

Isolate the variable x. First, distribute 3 to all terms within the parenthesis.

3(2x + 3) = 3(2x) + 3(3) = 6x + 9

6x + 9 = 9

Isolate the variable x. Note the equal sign, what you do to one side, you do to the other. First, subtract 9 from both sides.

6x + 9 (-9) = 9 (-9)

6x = 0

Divide 6 from both sides.

(6x)/6 = (0)/6

x = 0

0 is your answer.

A group walked 3/8 mile in 1/5 hour. Which is the groups walking speed in miles per hour

gogolik [260]

Answer:

The groups walking speed is $1\frac{7}{8}\frac{miles}{hour}$ or $1.875\frac{miles}{hour}$

Step-by-step explanation:

we know that

To find the speed divide the distance by the time

$\frac{(3/8)}{(1/5)}=\frac{15}{8}\frac{miles}{hour}$

Convert to mixed number

$\frac{15}{8}=\frac{8}{8}+\frac{7}{8}=1\frac{7}{8}\frac{miles}{hour}$
