Eighty, decreased by three times a
Marina86 [1]

Answer:

The number is 9.

Step-by-step explanation:

Lets write this as an equation first. We'll substitute the number for the variable <em>x</em>.

80 - 3x = 5x + 8

First, let's add 3x to both sides.

80 - 3x + 3x = 5x + 3x + 8

80 = 8x + 8

Next, let's subtract 8 from both sides.

80 - 8 = 8x + 8 - 8

72 = 8x

Finally, let's divide both sides by 8.

72/8 = 8x/8

9 = x

<em>"x" is 9.</em>

<em>So the secret number is 9.</em>

P.S.

This is my first answer to a Brainly question so please don't complain!

Marysya12 [62]

Answer:

9.7303888 miles

Step-by-step explanation:

Given the following :

Set target = 12 miles per week.

Miles ran on Monday = 4 3/4 miles

Miles ran on Wednesday = 3 1/3 miles

Miles ran on Friday = 1 11/17 miles

Number of miles covered for the week:

(miles covered on Monday + miles covered on Wednesday + miles covered on Friday)

= (4 3/4 + 3 1/3 + 1 11/17) miles

= (19/4 + 10/3 + 28/17) miles

= (4.75 + 3.33333 + 1.6470588) miles

= 9.7303888 miles
