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
Answer:
Option b, 112°
Step-by-step explanation:
<A+<B=180
or, 68+<B=180
or, <B=112

Answer:
<h2>slope = 4</h2>
Step-by-step explanation:
The formula of a slope:

We have the points (9, 10) and (7, 2).
Substitute:

We want to find 150% of 3000. since 150% is greater than 100%, it is expected that 150% 0f 3000 will also be greater than 3000.

Therefore, 150% of 3000 is equal to 4500.
