Answer:
x=lizards y=snakes
x+36=y x+y=214
x + x +36=214
2x=214-36
2x/2=178/2
x=89lizards y=89+36=125snakes
Step-by-step explanation:
f= female sankes m=male snakes
m+31=f
m+f=125
m+m+31=125
2m=125-31
2m/2=94/2
m=47 male snakes
f=47+31=78female snakes
Answer:
the top and bottom ones

Answer:
84.
Step-by-step explanation:
96 / (7 + 5) + 19 * 4
Use order of operations (PEMDAS* ).
Perform the operation in the parentheses first:
= 96/12 + 19*4
Now the divide and multiplication:
= 8 + 76
and finally the add:
= 84.

Answer:
17
Step-by-step explanation:
let the 4 consecutive odd numbers be n , n + 2 , n + 4 , n + 6 , then
n + n + 2 + n + 4 + n + 6 = 56 , that is
4n + 12 = 56 ( subtract 12 from both sides )
4n = 44 ( divide both sides by 4 )
n = 11
n + 2 = 11 + 2 = 13
n + 4 = 11 + 4 = 15
n + 6 = 11 + 6 = 17
The 4 consecutive odd numbers are 11 , 13 , 15 , 17
with the greatest being 17
The answer is B a2 +9ab-b2+3ab2
