A triangle has one side that measures x, and the other two sides each measure 4 inches less than x. The perimeter is 19 inches.
What is the measure of x?
5
3
9
2
Answer:
x=9
Step-by-step explanation:
x + x - 4 + x - 4 = 19
3x - 8 = 19
3x = 19 + 8
3x = 27
x = 9
Answer: x=9
Step-by-step explanation:
There are three sides 2 that are x-4 and 1 that is x. The equation would be
x+2(x-4)= 19 so you would simplify to get
X+2x-8=19 then 3x=27 then divide by three to get x=9

The selling price of an item is $390. It is marked down by 10%, but this sale price is still marked up from the cost of $270. Find the markup from cost to sale price.
Answer:
find the actual discount, multiply the discount rate by the original amount 'x'. To find the sale price, subtract the actual discount from the original amount 'x' and equate this to given sale price. Solve the equation and find the original amount 'x'.
Step-by-step explanation:
Sale Price = $11.34 (answer). This means the cost of the item to you is $11.34. You will pay $11.34 for a item with original price of $12.60 when discounted 10%. In this example, if you buy an item at $12.60 with 10% discount, you will pay 12.60 - 1.26 = 11.34 dollars.
The markup from cost to sale price is 81 dollars.
What is the cost price?Cost price, for instance, equals selling price plus profit ( when selling price and profit is given )
Cost is equal to Selling price plus Loss ( when selling price and loss is given )
The Cost price = 100 Selling Price + 100 + Profit
where the Selling Price and Profit Percentage are supplied.
The selling price of item = $390
cost = $270
10% × $390 = $39
Now subtract 39 from 390
390 - 39
351
Now subtract 270 from 351
351- 270
81
$81 is markup price .

Step-by-step explanation:
Answer: Finding the Inverse of a Function
First, replace f(x) with y . ...
Replace every x with a y and replace every y with an x .
Solve the equation from Step 2 for y . ...
Replace y with f−1(x) f − 1 ( x ) . ...
Verify your work by checking that (f∘f−1)(x)=x ( f ∘ f − 1 ) ( x ) = x and (f−1∘f)(x)=x ( f − 1 ∘ f ) ( x ) = x are both true.

Two pools were being filled. Pool A was being filled 1/8 of a gallon in 1/12 of a minute, and pool B was being filled at 3/8 of a gallon in 1/9 of a minute. Which pool is being filled up faster?
V=d/t
V1=1/8 × 12/1=12/8=3/2
V2=3/8 × 9/1 =27/8
Common denominator:
3/2=1 1/2 and 27/8= 24 3/8
so second pool because 24 3/8 is greater
