Answer:
Earned = 160 + 20d
Step-by-step explanation:
Seeing as Elmo works 20 hours per week at each job, that means he worked 20 hours at the $8 job and 20 hours at the $d job.
First find how much he earned from his $8/hr job.
(20)8 = 160
Elmo earned $160 at this $8/hr job.
Next, we know he earns $d/hr at his other job, and he works 20 hours at that job as well.
(20)d = 20d
Add the earnings from both jobs together.
160 + 20d = total earnings
Answer:
Hey there!
The first equation has no solutions, as it is parallel lines.
The second equation has infinitely many solutions, as it is basically the same line, and the two lines intersect at infinite points.
The third equation is just one solution.
Let me know if this helps :)
Answer:
x=20
Step-by-step explanation:
We can use similar triangle to find x. Put the smaller triangle over the larger triangle.
11 10
-------- = ----------
121+11 10 +5x+10
Combine like terms
11 10
-------- = ----------
132 20+5x
Using cross products
11 (20+5x) = 132*10
Distribute
220 +55x = 1320
Subtract 220 from each side
220-220 +55x = 1320-220
55x = 1100
Divide by 55
55x/55= 1100/55
x =20
Simplification of the equation 
is equal to (x² -24)/ 3x(x+3), restriction on the variables are x ≠0 , x≠ -3.
As given in the question,
Given equation
Simplify the given equation,
x/ 3(x+3) - 8/x(x+3)
= (x² - 24) / 3x(x+3)
Restriction on the variables for the above equation is,
x≠ 0 , x≠ -3
Therefore, simplification of the equation is equal to (x² -24)/ 3x(x+3), restriction on the variables are x ≠0 , x≠ -3.
