Answer:
17400
Step-by-step explanation: i might get this wrong but just do 1.74*10^4 and it should equal 17400
Set up an equation like this, where n represents the number:
2(n + 6) = 3(n - 6)
2n + 12 = 3n - 18
-n + 12 = -18
-n = -30
n = 30
The number is 30. You can even double-check by plugging 30 into each side of the original equation and simplifying:
2(n + 6) = 3(n - 6)
2(30 + 6) = 3(30 - 6)
2(36) = 3(24)
72 = 72

Answer:
Step-by-step explanation:
Let
x ----> the number of t-shirts
y ----> the cost of buying T-shirts from Paula’s Printing in dollars
take two points from the given data
we have
(2,43) and (4,86)
step 1
Find the slope
The formula to calculate the slope between two points is equal to
substitute the values in the formula
step 2
Find the equation of the line in point slope form
we have
substitute
step 3
Convert to slope intercept form
Isolate the variable y
This linear equation represent a proportional relationship (the line passes through the origin)
