Answer:

The answer is 7, 8 and 9. The Two-digit numbers are: ab, ac, ba, bc, ca, cb

The Sum of them is: 10a + b + 10a + c + 10b + a + 10b + c + 10c + a + 10c + b = 528

22a + 22b + 22c = 528

a + b + c = 528/22

a + b + c = 24      The only option of three different digits with the sum of 24 is 7, 8 and 9.

Hope this helps, stay safe, and merry christmas!

Answer:

1. w = 3l

2. k = 1/2 * b

Step-by-step explanation:

1.  w = 3l

   w = width     l = length

   Since we are solving the equation for the width, we can make the equation w = ? for now. since the width is equal to three times the length, we can make the equation w = 3l.

2. k = 1/2 * b

   k = kool-aid     b = beef    

   Since we are solving the equation for the kool-aid, we can make the equation k = ? for now. since the kool-aid is equal to half the beef sold, we can make the equation k = 1/2 * b

I hope this helped and please mark me as brainliest!

What’s is the slope line ?
Elena L [17]

Answer:

The slope of a line is a measure of its steepness. Mathematically, slope is calculated as "rise over run" (change in y divided by change in x).

Step-by-step explanation:

Slope, sometimes referred to as gradient in mathematics, is a number that measures the steepness and direction of a line, or a section of a line connecting two points, and is usually denoted by m. Generally, a line's steepness is measured by the absolute value of its slope,
