Answer:
Fred is 28 yrs old. Nathalie is 12yrs old
Step-by-step explanation:
Let Nathalie's age be x
Let Fred's age be a
x+a=40 yrs•••••1
4x+a=76yrs•••••2
a=40-x
Substitute a for 40-x in equation (2)
4x+40-x=76
3x=76-40
3x=36
x=12
a=40-12
a=28
Based on the charge to the artist and the amount the streaming services pay, the following are true:
- -50.
- 5.
- y = 5x - 50
- .
- 10,000 streams.
- 190,010,000 streams
<h3>What model can be derived for the streaming data?</h3>
The y-intercept would be the amount that the artist has before they start making any money. In this case that amount is -$50 because they will owe the distributor.
The slope is the change per unit which is $5.00 here.
The formula is therefore:
y = mx + b
y = Slope × x + b
y = 5 × x + (-50)
y = 5x - 50
The number of streams to pay off the distributor is when the profit is $0:
0 = 5x - 50
50 = 5x
x = 10 units
Number of streams:
= 10 units x 1,000
= 10,000 streams
To make a profit of $950,000, the units are:
950,000 = 5x - 50
5x = 950,000 + 50
x = (950,000 + 50) / 5
= 190,010 units
Number of streams is:
= 190,010 x 1,000
= 190,010,000 streams

Answer:
x + 61 = 411
Step-by-step explanation:
Let x = the number of adult tickets sold
Let x + 61 = the number of student tickets sold
x + x + 61 = 761
2x = 700
x = 350
