Make a proportion using the ratio (A:B) given and number of As and Bs really gotten in the class (
)
Cross multiply
2 * 40 = 5 * A
80 = 5A
Isolate A by dividing 5 to both sides
80/5 = 5A/5
16 = A
If 40 people in the class got B's then 16 people got A's
Hope this helped!

Answer:
758
Step-by-step explanation:
758 is the answer sheesh
I mean it would be 14.0 because it’s a whole number unless you are getting into 14 tenths or 14 hundredths then it’s like 0.14 or 0.014.
Answer: if you rounded it's = -4.8
Step-by-step explanation:
Answer:
24 =m
Step-by-step explanation:
We can use the angle bisector theorem
AB AC
--------- = ----------
BD DC
Substituting in known values
42 35
------ = -----------
m n
BC = 44 We know that 44 = m+n. Solving for n n = 44-m
42 35
------ = -----------
m 44-m
Using cross products
42(44-m) = 35m
Distribute
1848 -42m = 35m
Add 42m to each side
1848 -42m+42m = 35m+42m
1848 = 77m
Divide each side by 77
1848/77 = 77m/77
24 =m
