Answer:
2x+8b
Step-by-step explanation:
First since 1 and 8b are on the same side mutiply them:
1bx8=8b
So our new equation is 2x+8b
Answer:
Step-by-step explanation:
x+y = 175
y = 175 - x
f(x) = (x+3)(y+4)
= x(175-x) + 3(175-x) + 4x + 12
= 175x - x² + 525 - 3x + 4x + 12
= -x² +176x + 537
f'(x) = -2x + 176
maximum when x = 88
y = 175-x = 87
Answer: y= -2x + 3
Step-by-step explanation:
$ per min is a rate. you multiple by minutes to get dollars.
A = 10x
B = 5x + 20
set them equal to find minutes, x.
10x = 5x + 20
10x - 5x = 20
5x = 20
x = 4
A mixed number that is equivalent to 16/3 is
