Answer:
Kindly check explanation
Step-by-step explanation:
Given the expression :
Jacob's yearly income :
2000x + 3000 ; x = number of hours worked per week.
Carlos income :
3800x - 40000
Managers prediction = 35
Jacob.: 2000(35) + 3000 = 73000
Carlos : 3800(35) - 40000 = 93000
Carlos will earn more than Jacob given the manager's prediction.
Number of hours required so they can earn the same amount :
2000x + 3000 = 3800x - 40000
3000 + 40000 = 3800x - 2000x
43000 = 1800x
x = 43000/1800
x = 23.88
x = 24 hours
It is a gain because she sold it for more than she bought it for
Answer:
x=2
Step-by-step explanation:
If this figure is a rhombus, then the two sides have to be equal:
3x+9=8x-1
Move like terms to one side (note that when you move it, the sign flips. Ex: - becomes +)
3x-8x=-9-1
-5x=-10
Divide both sides by -5
x=2
C. -10
(20+2x)/(5-x)
Multiply both sides by lowest common denominator, simplify
2x + 20 = 0
2(x + 10) = 0
factor out 2 from 2x+20
