-2/3x + 2.8 = -8.2 what is x
Add 2.8 on both side of the equation
-2/3x=-11
Divide both side by -2/3
x=33/2
Check: -2/3(33/2)+ 2.8 = -8.2
-11+2.8=-8.2
-8.2=-8.2
Answer is x=33/2
Answer:
so I believe we can do 15% of 45, so that is 6.75.
so now we do:
45.00
<u>+ 6.75</u>
<u><em>51.75 is your answer!</em></u>
please mark brainliest if correct!
Answer:
x = 75°
Step-by-step explanation:
Sum of angles in a triangle: 180°
So,
50°+55°+x=180°
105°+ x = 180°
Subtract 105° from both sides
x = 75°
Answer:
Option C.
Step-by-step explanation:
Total population = 1000 snails
AA = 160 snails
Aa = 480 snails
aa = 360 snails
Frequency of each type.



Now, we get

he frequency of the A allele in this population is 0.4.
Therefore, the correct option is C.
