Yes, 7.5 can be multiplied by 2 to get 15.


Provided that number / 2 =/= imaginary number, then you can always multiply by two to reach said number.


Example 1)

8

8 / 2 = 4

4 * 2 = 8


Example 2)

4

4 / 2 = 2

2 * 2 = 4


Example 3)

15 / 2 = 7.5

7.5 * 2 = 15


Hopefully I haven't misinterpreted your question.

A border to surround a picture is to be cut from a 10 1/2 in by 10 1/2 in mat board. If picture is 8 3/4 in by 8 3/4 in what is
Lilit [14]
Since the dimensions of the length and width are equal, then the board and the picture are squares. The width of the board is the margin surrounding the picture. Let's denote the width to be x. The length of the picture plus the length of the width at both ends should equal the length of the board. So, the equation should be:

10 1/2 in = 8 3/4 + 2x
Solving for x
x = 7/8 inches

Find the sum of a finite arithmetic sequence from n = 1 to n = 10, using the expression 3n − 8.
maw [93]

Answer:

The answer is 85

Step-by-step explanation:

The equation used to find the sum of an arithmetic series is: (n/2) * (a1 + an).

n in this case is 10 (the number of numbers in the series)

an is 22 (plug in 10 to the expression 3n-8)

and a1 is -5 (plug in 1 to the expression 3n-8)

so when you plug everything in to the final equation, you get

(10/2) * (-5 + 22)

5 * 17

85
