Answer:
the number is 5
Step-by-step explanation:
We have to find the equation to solve the problem.
Let the number be x
lets write one more than seven times the difference of a number and 4 in mathematical form
1. Difference of number and 4 will be written as x - 4
now
2. seven times the difference of a number and 4 will be written as
7*( x - 4)
3. one more than seven times the difference of a number and 4 is expressed as
1 + 7*( x - 4)
_____________________________________________
1 + 7*( x - 4) is equal to twice the difference of the number and 1
4. difference of the number and 1 is x - 1
5. twice the difference of the number and 1 is 2*(x-1)
Thus,
1 + 7*( x - 4) = 2*(x-1)
=> 1 + 7x - 28 = 2x -2
=> 7x - 27 = 2x - 2
adding 27 both sides
=> 7x - 27 + 27 = 2x - 2 + 27
=> 7x = 2x + 25
subtracting 2x from both sides
7x -2x = 2x + 25 - 2x
=> 5x = 25
dividing both side by 5
5x/5 = 25/5
x = 5
Thus, the number is 5 answer
Answer:
I believe 252
Step-by-step explanation:
Answer: 9+3×9×9 = 9+243 = 252 possible 3-digit numbers with at least
2 digits the same.
Answer:
-2-p
Step-by-step explanation:
(p-2)x=4-p^2
(4-p^2)/(p-2)
-2-p
The answer is: "42" .

From the stem-and-leaf plot provided, we can write the following values from the data set, from least to greatest:
____________________________________
{15, 18, 46, 50, 50, 50, 50, 57} ;
____________________________________
To calculate the mean, we take the sum of all the values in the data set; that is, we add up all the values in the data set; and we divide that sum total by the number of values in the data set.
In our data set, we have EIGHT (8) values.
To calculate the mean:
_________________________
{15 + 18 + 46 + 50 + 50 + 50 + 50 + 57} / 8 = the mean {our answer}.
________________________________________________________
→ {15 + 18 + 46 + 50 + 50 + 50 + 50 + 57} / 8 =
→ {336} / 8 = 42 .
_________________________________________________________
The answer is: " 42 " .

Hope this explanation is helpful.
The school did reach the goal because if you add the games, concessions and donations you get $1232 and if you subtract 28 from it you get $1204 and if you subtract 75 from that you get $1129.
