You have two jobs. One job pays nine dollars per hour and the other job pays $7.50 per hour. You worked 18 hours last week and e
sveta [45]

Answer:

Y =\frac{16.5}{1.5}= 11

X = 18-11=7

And then we conclude that for the first job he works 7 hours and for the second job 11 hours

Step-by-step explanation:

We can define the following notation:

X represent the number of hours worked for one job

Y represent the number of hours worked for the other job

p_x = 9 represent the hourly payment for the first job

p_y = 7.50 represent the hourly payment for the other job

And we can define the following equations:

X+ Y= 18   (1) represent the toal number of hours worked

9X +7.5 Y = 145.50  (2) represent the total amount earned

From equation (1) if we solve for X we got:

X = 18-Y (3)

Replacing equation (3) into equation (2) we got:

9(18-Y) +7.5 Y =145.50

And after solve the equation we can find the value of Y:

162 -9Y +7.5 Y =145.50

16.5 = 1.5 Y

Y =\frac{16.5}{1.5}= 11

And solving for X from equation (3) we got:

X = 18-11=7

And then we conclude that for the first job he works 7 hours and for the second job 11 hours

Simplify 3-(4x-5)+6.
Leviafan [203]
3 + -4x = 5(x +6)

Re-order the terms:

3 + -4x = 5(6 + x)
3 + -4x = (6 . 5 + x . 5)
3 + -4x = (30 + 5x)

Solving:

3 + -4x = 30 + 5x

Solving for variable "x"

Move all terms containing "x" to the left, all the other terms to the right.

Add "-5x" to each side of the equation.
3 + -4x + -5x = 30 + 5x + -5x

Combine like terms: 
-4x + -5x = -9x
3 + -9x = 30 +5x + -5x

Combine like terms: 
5x + -5x = 0
0 + -9x = 30 +0
3 + -9x = 30

Add "-3" to each side of the equation.
3 + -3 + -9x = 30 + 3

Combine like terms: 
3 + -3 = 0
0 + -9x = 30 + -3
-9x = 30 + -3

Combine like terms: 
30 + -3 = 27
-9x = 27

Divide each side by "-9".
x = -3

Simplifying:
x = -3
