Answer:
C
Step-by-step explanation:
Option c gives the actual representation of the question
Step-by-step explanation:
3h - 10 = 35 ➡ 3h = 35 + 10 ➡ 3h = 45 ➡h = 15
This can be done with simple concept of PERMUTATIONS AND COMBINATIONS.
The number can arrange themselves repeatedly to form different numbers. The possible number of ways they can do so is 3×2×1=6
3
×
2
×
1
=
6
ways.
ALTER,
You can arrange these number in 3!
3
!
ways, which finally produces the same result i.e 3!=3×2×1=6
3
!
=
3
×
2
×
1
=
6
ways.
So you need to find the $ for one hour of work
if 16=135
1 hour= $8.50
$8.50*24= $204
answer=$204
hope this helps :)
-3x-3y=-24
divide the equation by 3
-x-y=-8
multiply -1
x+y=8
second equation
x+y=8
same equation
so answer is
x+y=8
