A median i am 100% sure and i am in 11th grade so I can’t be wrong ;)
-9, it is between -2 and -10 and it is the least possible integer
Answer:
Jelly beans: $6 for 1 kg
Gummy worms: $7 for 1 kg
Step-by-step explanation:
In this question, we need to find the cost of 1kg of jelly beans and gummy worms.
To do this, make equations for both scenarios and solve:
2j + 2g = 26
2j + 3g = 33
Turn the bottom equation negative, as we will first solve for gummy worms (g).
2j + 2g = 26
-2j - 3g = -33
Solve:
-g = -7
Divide both sides by -1.
g = 7
We now know that gummy worms cost $7 for 1 kg
To solve for jellybeans (j), plug in 7 to g in one of the equations and solve:
2j + 2(7) = 26
2j + 14 = 26
Subtract 14 from both sides.
2j = 12
Divide both sides by 2.
j = 6
Jellybeans cost $6 for 1 kg.
Check answer by plugging in values to one of the equations:
2(6) + 2(7) = 26
12 + 14 = 26
26 = 26
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.
Subtract 43 from both sides
-6p=-30
Divide both sides by -6
p=5
Final answer: p=5
