The equation is 4 meatballs for every adult and 3 for every child. Replace a and c and solve:
M = 4(20) + 2(8)
M = 80 + 16
M = 96
They need 96 meatballs.
4*25= 100. There are 26 tables. At each of the 25 tables 4 people are sitting. Which means 100 people are sitting in complete tables of 4 people. That means that at the 26th table 3 people are sitting. 103-100= 3. Hope that helps. :)
Answer:
C i think but im not 100% sure
Step-by-step explanation:
Answer:
f(7)=58
b(-2)-a(12)=-188
Step-by-step explanation:
f(7)=(7)^2+9
49+9
f(7)= 58
b(-2)-a(12)=8(-2)-14-13(12)-2
-16-14-156-2
=-188
Answer:
2
Step-by-step explanation:
Plug in 2 for c in the equation:
x² + 3x + 2
x 2
x 1
(x + 2)(x + 1)
Check. Use the FOIL method:
(x)(x) = x²
(x)(1) = x
(2)(x) = 2x
(2)(1) = 2
x² + x + 2x + 2
Combine like terms:
x² + (x + 2x) + 2
x² + (3x) + 2
2 can be a answer for c.
