Answer:
-9 =x
Step-by-step explanation:
We know these are similar triangles
We can use ratio's to solve
Let CS = y and XR = y+y or 2y
y x+19
------ = ------------
2y x+29
We can simplify the ratio on the left by dividing by y
1 x+19
------ = ------------
2 x+29
Using cross products
1(x+29) = 2(x+19)
Distribute
x+29 = 2x+38
Subtract x from each side
x-x+29 = 2x-x+38
29 = x+38
Subtract 38 from each side
29-38= x+38-38
-9 =x
Answer:
store one
Step-by-step explanation:
Store One:
$720(0.50)=$360
$720-$360=$360
Store Two:
$720(0.30)=$216
$720-$216=$504
$504(0.20)=$100.8
$504-$100.8=$403.2
Answer: (a) Yes. The table is a function.
<u>Step-by-step explanation:</u>
In order to be a function, there cannot be any duplicate x-values.
In the given table, each x-value is different so this IS a function.

, and
. Subtracting this from the numerator gives a remainder of

, and
. Subtracting this from the previous remainder gives a new remainder of

is not a multiple of
, so we're done. Then
