Answer:
Small: 178
Large: 84
Step-by-step explanation:
L + S = 262
S = 262 - L
3L + S = 430
3L + 262 - L = 430
2L = 168
L = 84
S = 262 - 84
S = 178
Answer:
an = 4n +5
Step-by-step explanation:
First we need to find a common difference
d = a2-a1 = 13-9 = 4
The formula for an
an =a1+d(n-1)
an = 9 + 4(n-1)
Distributing
an = 9+4n-4
Combine like terms
an = 4n +5
Answer:
correct
Step-by-step explanation:
Answer:
y = 
Step-by-step explanation:
3x + 7y = 29 ( subtract 3x from both sides )
7y = 29 - 3x ( divide both sides by 7 )
y =
