The perimeter of any shape is a measure of the length of the peripheral of that shape.
For a triangle, it is an addition of the length of the 3 sides.
P = a + b + c where a, b, c are the lengths of the individual sides.
p = 10x + 5y = (3x + 4y) + (5x - y) + c
Collecting like terms on the RHS, we have
p = 10x + 5y = 8x + 3y + c
Subtracting 8x + 3y from both sides to give c leaves us with
10x + 5y - (8x + 3y) = c
c = 10x - 8x + 5y - 3y
c = 2x + 2y
Answer:
38.72%
Step-by-step explanation:
Estimated attendance = 1,000
The actual value of attendance = 1,632
We need to find the percent error of Shaun's estimate. Using the formula as follows :

Put all the values,

So, the percent error of Shaun's estimate is 38.72%.
Answer:
p(x) = 0.85x
t(x) = 1.065x
(t o p)(x) = 0.9x
$2700
Step-by-step explanation:
If the marked price is $x, then the function p(x) that gives the price of the riding lawn mower after 15% discount will be

where x is the marked price.
Now, the function that gives the total cost with sales tax will be given by

where x is the discounted price.
Therefore, the composite function that gives the total cost of the riding lawn mower on sale is given by
(t o p)(x) = 1.065(0.85x) = 0.9x ............ (1)
where x is the marked price.
If the marked price x = $3000, then Mr. Rivera has to pay for the riding lawn mower, from equation (1),
(t o p)(3000) = 0.9 × 3000 = 2700 dollars. (Answer)
