Solve the literal equation 2xy - xz = 4 for x
x = 4/(2y-z)
y =/ z/2
Answer:
see below
Step-by-step explanation:
We'll cal the first integer x and then the rest of them will be x + 1, x + 2, x + 3 and x + 4. We can write x + 5(x + 2) = 3(x + 1 + x + 3 + x + 4) - 41.
x + 5x + 10 = 3(3x + 8) - 41
6x + 10 = 9x + 24 - 41
6x + 10 = 9x - 17
3x = 27
x = 9
The numbers are 9, 10, 11, 12, 13.
Hello!
To find the markup you have to subtract the selling price from the store price so
91 - 65 = 26
So there is a $26 markup
Hope this helps!
