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
X-2 is the answer hope this helps and I hope I’m not answering too late
24 because
6x4=24
8x3=24
since that makes the two denominador alike than they are common (alike) and they are the denominators (duh)
-Dafne
S/18=64/288 multiply both sides by 18
s=1152/288
s=4 ft
So Sarah is four feet tall.
