8 and 1/2 yeah this is the answer
Answer:
20 pastries
Explanation:
It is a system of equations.
1. write equations:
2c+3p=120
c+p=50
2. cancel out a variable
2c+3p=120
-2(c+p=50) ---------- -2c+-2p= -100
3. solve for p
p=20
Answer:
Equation which can be used to find the number of weekly payments w
is 300 = 60 + 3 w.
Step-by-step explanation:
Here, the selling price of the TV =$300
The initial TV payment = $60
Per week payment of TV = $30
The number of weeks, the payment is made = w
So, the amount paid for TV in w weeks = w x ( Payment in 1 week)
= w x ( $30) = 30 w
So, The total SP of TV = Initial Payment + Payment made in w weeks
⇒ 300 = 60 + 3w
Hence, equation which can be used to find the number of weekly
payments w is 300 = 60 + 3 w.
