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
I don’t even know the answer to be honest
Answer:
Hello!!! Princess Sakura here ^^
Step-by-step explanation:
2 (no)
-5 (yes)
9 (no)
7 (no)
The perimeter is equal to 60 feet and has the formula:
Perimeter = 2 l + 2 w
60 = 2 l + 2 w
The area is equal to 200 square feet and has the formula:
Area = l w
200 = l w
Rewriting area in terms of l:
l = 200 / w
Combining this with the perimeter formula:
60 = 2 (200 / w) + 2 w
60 = 400 / w + 2 w
Multiplying all by w:
60 w = 400 + 2 w^2
Dividing by 2 and rearranging:
w^2 – 30 w = - 200
Completing the square:
(w – 15)^2 = - 200 + (-15)^2
(w – 15)^2 = 25
w – 15 = ±5
w = 10, 20
Hence the dimensions of the garden is 10 feet by 20 feet
Answer:
Expression
Step-by-step explanation:
Given expression :
4a+3b-6cx9
So this is expression not equation because equation consist zero on the righ side
Example: ax+b=0 (This is equation )
And
ax+b (This is expression)
