Answer:
Below
Step-by-step explanation:
281.6x20%= 56.32
281.6+56.31=337.91
337.91x12%=40.55
337.91+40.55=378.46
Answer:
3^14
Step-by-step explanation:
(3^9/3^-5)
We know that when we have a^b / a^c = a^(b-c)
3^(9 - -5)
3^(9+5)
3^14
Answer:
208 history books
124 chemistry books
Step-by-step explanation:
Let a = total number of books
b = number of history books
c = number of chemistry books
a = b + c
We know that a is equal to 332 and c = b - 84
Let's substitute this value to our equation and solve for b first. Now we get:
332 = b + ( b - 84)
332 = 2b - 84
332 + 84 = 2b
416 = 2b
b = 208
Now we can solve for c
332 = 208 + c
332 - 208 = c
c = 124
Now let's check
a = 332
b = 208
c = b - 84 = 208 - 84 = 124
