Answer:

the number is 8/3 (= 2 2/3)

Step-by-step explanation:

let the number be x

"3 times a number" --> 3x

"one less than 3 times a number" --> (3x - 1)

"one less than 3 times a number is 7" --> (3x - 1) = 7  (solve for x)

3x - 1 = 7    (add 1 to both sides)

3x = 7 + 1

3x = 8   (divide both sides by 3)

x = 8/3

Help!! math algebra 1
andre [41]

Answer:

-ab/1

Step-by-step explanation:

The multiplicative inverse of x/y is y/x, because when multiplied it equals 1.

x/y time y/x = xy/xy, which equals one.

In this case, -1/ab times -ab/1 = -1ab/-1ab, which equals one.
