Answer:

Z = Ma = ba

You made a typo. One of those = signs should either  

be a + and a -.  Here are all possibilities:

1.     Z+Ma = ba, solve for a

     Ma-Ba = -Z

    a(M-B) = -Z

         a = -Z/(M-B)

2.        Z = Ma+ba, solve for a

     Ma+ba = Z

    a(M+b) = Z

         a = Z/(M+b)  

3.     Z-Ma = ba, solve for a

         Z = Ma+ba

     Ma+ba = Z

    a(M+b) = Z

         a = Z/(M+b)

4.       Z = Ma-ba, solve for a

     Ma-ba = Z

    a(M-b) = Z

         a = Z/(M-b)

The sum of five consecutive positive integers is 2020. Find the largest of these numbers.
lawyer [7]

Answer:

406

Step-by-step explanation:

Five consecutive positive integers = x, (x+1), (x+2), (x+3), (x+4)

x + (x+1) + (x+2) + (x+3) + (x+4) = 2020

5x + 10 = 2020

5x = 2020-10

5x = 2010

x = 2010÷5

x = 402

The largest of the number is = x+4

x+4 = 402 + 4 = 406

A 13ft board is to be cut into three pieces, two equal length ones and the third 9in shorter than each of the other two. If cutt
vaieri [72.5K]

Answer:

The pieces are 55 inches, 55 inches and 46 inches long

Step-by-step explanation:

A 13ft board is to be cut into three pieces consisting of two equal length ones. The third one is 9in shorter than each of the other two.

Let us first convert the length of the board to inches:

1 ft = 12 inches

13 ft = 12 * 13 = 156 inches

Let the length of each of the other two pieces be x.

Therefore, the length of the third piece is (x - 9)

Therefore, the sum of the lengths of the three pieces is equal to 156 inches. This means that:

x + x + (x - 9) = 156

x + x + x - 9 = 156

=> 3x = 156 + 9

3x = 165

x = 165 / 3 = 55 inches

Each of the first two pieces are 55 inches long.

The length of the third piece will be:

55 - 9 = 46 inches

The pieces are 55 inches, 55 inches and 46 inches long.

If the company provides 1 1/4 vacation days to its employees every month,how many vacation days does an employee get every year?
FromTheMoon [43]
We know there are 12 months in a year so we would multiply 1 1/4 by 12. We can write 1 1/4 as 1.25 (to make it easier to multiply). 12x1.25=15
Your answer is 15 vacation days in one year
