Answer:
15 2/3
Step-by-step explanation:
R = 3x + 9y
7 = 3x + 9(6)
7 = 3x + 54
-47 = 3x
x = -15.6
Answer:
the total late fee

the x will stand for each day and 0.25 is the cost so you will multiply 0.25 by x to get the total overdue
ANSWER
EXPLANATION
Given information
The sum of the two numbers is 76
The larger number is 16 more than 2 times the smaller number
Let the two numbers be x and y
x ----> Larger number
y ----> smaller number
To find the value of x and y, follow the steps the below
Step 1: Write the algebraic expressions for the statement given
The sum of the two numbers is 72
Mathematically, this can be expressed as
Also, the larger number is 16 more than twice
Step-by-step explanation:
x= Number of small pages
y= Number of full pages
1 x + 1 y = 21 .............1
Total words
1200 x + 1500 y = 27000 .............2
Eliminate y
multiply (1)by -1500
Multiply (2) by 1
-1500 x -1500 y = -31500
1200 x + 1500 y = 27000
Add the two equations
-300 x = -4500
/ -300
x = 15
plug value of x in (1)
1 x + 1 y = 21
15 + y = 21
y = 21 -15
y = 6
y = 6
x= 15 Number of small pages
y= 6 Number of full pages
Answer:
x=17
Step-by-step explanation:
7x+15=4x+66
3x=51
x=17
