Answer: n/5 - 10 = 18: this would be the equation. Your answer would be 140.
Step-by-step explanation: Let consider the number as ‘X’
Quotient of a number and 5 can be written as
X divided by 5
Ten subtracted from the quotient of a number and 5 can be written as
(X divided by 5)-10
Ten subtracted from the quotient of a number and 5 is 18 can be written as
(X divided by 5)-10=18
By solving the above equation, find ‘X’
(X divided by 5) = 18 + 10
X/5=28
X = 28 x 5 = 140
Answer:
Step-by-step explanation:
Y = 389.10 - 14.6 X.
Here when X increases Y decreases so correlation coefficient is negative .
correlation coefficient = - √ .657
= - .81

Answer:
x = 1
Step-by-step explanation:
Solve using inverse operations
5 ( x + 2 ) - 7 = 3x + 5
first distribute the 5
5x + 10 - 7 = 3x + 5
simplify the expression
5x + 3 = 3x + 5
Inverse operations, then simplify
5x + 3 = 3x + 5
-3 -3
5x = 3x + 5 - 3
5x = 3x + 2
-3x -3x
2x = 2
/2 /2
x = 1
4 pups x 3 pounds of food a day is 12 pounds a day, plus 4 for felix = 16 pounds a day. 16 x 8 is 128 pounds of food for 8 days
