Rickroll
Step-by-step explanation:
Answer:x=-1
Step-by-step explanation:Step by step solution :
Step 1 :
Equation at the end of step 1 :
8 • (2x + 9) - 56 = 0
Step 2 :
Step 3 :
Pulling out like terms :
3.1 Pull out like factors :
16x + 16 = 16 • (x + 1)
Equation at the end of step 3 :
16 • (x + 1) = 0
Step 4 :
Equations which are never true :
4.1 Solve : 16 = 0
This equation has no solution.
A a non-zero constant never equals zero.
Solving a Single Variable Equation :
4.2 Solve : x+1 = 0
Subtract 1 from both sides of the equation :
x = -1
One solution was found :
x = -1
Answer:
Dorinda worked at Job A for 11 hours
Step-by-step explanation:
Step one
This is a word that leads to simultaneous.
Let us begin by modeling the system of equation from the problem
Let x and y be the number of hours worked in both jobs A and B respectively
Step two
x+y=30---------1
7.5x+8y=234.50----2
Solving the equations simultaneously we have
1. Multiplying equation 1 by 8 and equation 2 by 1 and subtracting from equation 2 to find y
8x+8y=240---------1
- 7.5x+8y=234.50----2
=0.5x=5.5
x=5.5/0.5
x= 11hrs
Substituting x=11 in equation 1 we can find y
11+y=30
y= 30-11
y= 19hrs
