I'm not 100% sure, but I believe the answer would be:
D. For every additional adult at the park, the number of children increases by about 7.
P.S. good luck on the 6.10, fellow classmate!
3 add 2 is 5 and then divide 125 by 5 which is 25. Then times 25 by the ratio ,which is 2, and the answer 50.
I believe this is incomplete what are the choices
Answer:
Step-by-step explanation:
A) Use the distributive property to eliminate parentheses. Then combine like terms. (The only "like terms" are the constants.)
... = 12 +3·2y +3·(-3) . . . use the distributive property to multiply each term in parentheses by the factor 3 outside those parentheses
... = 12 +6y -9 . . . . . . . . simplify
... = 6y + (12 -9) . . . . . . group like terms together
... = 6y + 3 . . . . . . . . . . simplify
___
B) Look for factors of each term that are also found in the other term.
... 18b has factors 3×6×b
... 12 has factors 2×6
The only common factor is 6, so we factor that out using the distributive property.
... 18b -12 = 6(3b -2)

<em>Comment on factoring</em>
For factoring problems, it helps immensely if you know your times tables and some of the rules for divisibility. (Even numbers are divisible by 2, numbers ending in 0 or 5 are divisible by 5, numbers whose sum of digits is divisible by 3 are divisible by 3, for example.)
Answer:
c
Step-by-step explanation:
6x² + 54x + 120 = 0
divide by 6
x² + 9x + 20 = 0
(x² + 5x) + (4x + 20) = 0
x(x + 5) + 4(x + 5) = 0
(x + 4) (x + 5) = 0
x + 4 = 0, x + 5 = 0
x = -4, x = -5
