So there are 50 teens total
16% have no sibblings
so we must find 16% of 50
16%=16/100=0.16
'of' can be translated as multiply so
0.16 times 50=8
there were 8 teens who have no sibblings
Answer:
1, 3, 4 i hope this helps ;)
Step-by-step explanation:
Given that,
Total cost function, C (x) = 43x + $1850
The revenue function R (x) = $80x
To find,
The number of units that must be produced and sold to break even.
Solution,
At break even, cost = revenue
43x + $1850 = $80x
Subtract 80x from both sides.
43x + 1850 -80x = $80x -80x
1850 = 80x-43x
37x = 1850
x = 50
So, the required number of units are 50.
Line 1 and line 4 are parallel
Step-by-step explanation:
Two lines are said to be parallel if they have same slope.
In order to compare the lines given, we have to write them all in the same form, and then compare their slopes.
Line 1:

Applying distributive property,

Line 2:

Line 3:

Applying distributive property,

Line 4:

re-arranging,

Now we have rewritten all the lines in the form
, where m is the slope. By comparing the values of m, we see:

Therefore, the lines which are parallel are line 1 and line 4.
