Answer:
I think you would have to add 12.5 to the 5
Step-by-step explanation:
there are 120 red blood cell, what you do is 10*2=20*6 = 120
Okay, So We Need To Solve For X, So We Can Solve The Expression:
6x - 5.
Lets Begin.
-17x - 9 = 8.
So, We First Need To Add 9 To Both Sides.
-17x = 8 + 9
8+9 = 17.
-17x = 17
Divide.
-17x/-17 = 1x = x.
So:
X = 17/-17
17/-17 = -1
So:
X = -1
Now, Plug In The Value For The Expression.
6 * (-1) - 5
6 * (-1) = -6
(-6) - 5 = -11.
So, Our Value For 6x - 5 Is -11.
M=(-22)
m+(-10)=-33
add 10 to -33
M=(-22)
Answer:
option (B) 20
Step-by-step explanation:
Data provided in the question:
Number of photographs initially sold = 20
selling price of first 20 photographs = $10 each
Therefore,
Revenue from 20 photographs = 20 × $10 = $200
Selling price of further photographs = $15
Let the number of additional photographs sold be 'x'
thus,
total revenue = $200 + $15x
now,
according to the question
80% of ($200 + $15x) = $400
or
0.80 × ($200 + $15x) = $400
or
($200 + $15x) = $500
or
$15x = $300
or
x = 20
Hence,
the answer is option (B) 20
