Answer:
14 children
Step-by-step explanation:
Let y be number of children.
Let T be the total cost for the party.
The recreation center offers a children’s birthday party for $75 plus $5 for each child. This implies that:
T = 75 + 5y
The total cost for Payton’s birthday party is $145. We can find the number of children(y) present by doing the following:
T = 75 + 5y
But T = 145
145 = 75 — 5y
Collect like terms
145 — 75 = 5y
70 = 5y
Divide both side by the coefficient of y i.e 5
y = 70/5
y = 14
Therefore, there are 14 children present at Payton’s birthday party

Answer:</h3>
y = -3x +2
<h3>
Step-by-step explanation:</h3>
The y-intercept is at +2, so that is the value of the added constant (b).
The line goes down 3 units for each unit to the right, so the slope (m) is ...
... m = ∆y/∆x = -3/1 = -3
Then in the form ...
... y = mx + b
with m=-3 and b=2, your line's equation is ...
... y = -3x +2
It so easy just punch all these numbers into your calculator (if u have one)
24 divided by 3 = 8
So if the barge takes only 2 hours during the return trip. We multiply 2 hours by 8 miles to get a total of 16 hours.
The answer is 16
