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.

Explain:
The ballon thing is getting longer if we fly them, so we can not accelerate it.
The length of the triangle doesn't change.
Paper airplane does shrinks, so the answer is no.
x + y = 35
5x + 2y = 100
Solve for y on one of the equations.
y = 35 - x
Plug it in to the other equation.
5x + 2(35 - x) = 100
5x + 70 - 2x = 100
3x + 70 = 100
3x = 30
x = 10
Plug x into an equation
x + y = 35
10 + y = 35
y = 25
Therefore your answer is A. 10 problems worth 5 points and 25 problems worth 2 points.
