Answer:
Adults = x
Students = y = x + 40. 40 more student than adult
Adult = $8, Student = $6
Total for Adults = 8*x = 8x
Total for students = 6*y = 6y
Total = $1920
8x + 6y = 1920
Hence system of equations are:
y = x + 40
8x + 6y = 1920
N+(n+2)+(n+4)=165
add everything together to get
3n+6=165
Subtract 6 from each side
3n=159
divide by 3
n=53
the numbers are 53,55,57

Answer:
P = -2600/3 t + 25600/3
P = -8200/3
Step-by-step explanation:
t is the time in years since 1990, so two points on the line are (5, 4200) and (8, 1600).
Using the points to find the slope:
m = (y₂ − y₁) / (x₂ − x₁)
m = (1600 − 4200) / (8 − 5)
m = -2600/3
Now writing the equation in point-slope form:
P − 4200 = -2600/3 (t − 5)
Converting to slope-intercept form:
P − 4200 = -2600/3 t + 13000/3
P = -2600/3 t + 25600/3
In 2003, t = 13:
P = -2600/3 (13) + 25600/3
P = -8200/3
The slope of the line is 0.35
x = number of items sold
y = total price in dollars
Therefore,
using slope formula,
The slope is rise over run. The slope of a line is the measure of its steepness.
<h3>Slope equation:</h3>
where
y₂ = 3.85
y₁ = 2.45
x₂ = 11
x₁₁ = 7
Therefore,
m = 3.85 - 2.45 / 11 - 7
m = 1.4 / 4
m = 0.35
