I need help on my pre-algebra homework, pleaseJoy recently hired a landscaper to do some necessary work. On the final bill, Joy was charged a total of $1096. $460 was listed for parts and the rest for labor. If the hourly rate for labor was $53, how many hours of labor was needed to complete the job?
(A) First, write an equation you can use to answer this question. Use x as your variable.
The equation is
(B) Solve your equation in part (A) to find the number of labor hours needed to do the job.
Answer: The number of labor hours was __________________.
Answers
Equation: 53x + 460 = 1096
Solution 1096 - 460 = 53x
636/53=x
12=x
12 hours

Answers
48,6% = 486/1000
971,26 £ * 0,486 ≈ 472,03 £
..................................................
b) 78.24% of £12.82
78,24% = 0,7824
12,82 £ * 0,7824 ≈ 10,03 £
..................................................
c) 42.15% of £7876.42
42,15% = 0,4215
7876,42 £ * 0,4215 ≈ 3 319,91 £

d) 0.57% of £60000
0,57% = 0,0057
60 000 £ * 0,0057 = 342 £

Arithmetic operations can be used to change linear equations in form ax+by=c to y=mx+b form and vice versa and this can be determined by simple subtraction and division operation.
Given :
ax + by = c
y = mx + c
The following steps can be used to change the linear equation in form (ax+by=c) to (y=mx+b) form:
Step 1 - Write the equation.
ax + by = c
Step 2 - Subtract ax from both the sides in the above equation.
ax + by - ax = c - ax
by = c - ax
Step 3 - Divide by 'b' from both sides in the above equation.
By following the above steps equation (ax + by = c) can be converted into (y = mx + c).
The following steps can be used to change linear equation in form (y = mx + c) to (ax + by = c) form:
Step 1 - Write the equation.
y = mx + c
Step 2 - Subtract mx from both sides in the above equation.
y - mx = c + mx -mx
y - mx = c
By following the above steps equation (y = mx +c) can be converted into (ax + by = c).
For more information, refer to the link given below:
by = c - ax
y = c/b - ax/b
Since c/b will be a constant, you can replace it with any variable (i.e. b), and so that represents the y-intercept and a/b will also be a constant, so that can also be replaced by any variable (i.e. m), and it represents the slope.
