Answer:

Step-by-step explanation:
Given:



(segment addition postulate)
(substitution)
(subtracting 17 from each side)

(Subtracting 5y from both sides)


(dividing both sides by -2)

Plug in the value of y


X - 17 = -57
-17. -17
x = -74

Answer:
Rita paid 47,500 dollars for the purchase price.
Step-by-step explanation:
We are given the sales tax on a new car is directly proportional to the purchase price of the car which means there is is something k such that
when you multiply it to the sales tax you get the purchase price.
Let's set this equation:
y=kx
Let y represent the purchase price and x the sales tax.
The second sentence tells us that (x,y)=(1500,30000).
We can plug this into y=kx to find the constant k. (Constant means it stays the same no matter what the input and output is).
So we have:
30000=k(1500)
300 =k(15) I went ahead and divided previous equation by 100.
Now divide both sides by 15:
300/15=k
Simplify:
20=k
So the equation to use the answer the question is
y=20x
where y is purchase price and x is sales tax.
So we want to know the purchase price on a car if the sales tax is 2375.
So replace x with 2375:
y=20(2375)
y=47500
Answer:
Medium
Step-by-step explanation:
The computation is shown below:
The cost for the small and medium bag is shown below:
As we know that
1kg = 1000g
So 3kg = 3000g
Now for small bags
= 0.95 ÷ 250 × 3000
= £11.40
For medium bags
= £1.80 ÷ 500 × 3000
= £10.80
So here the medium bag would represent the better value
128, because it’s actually 256 but 256/ 2= 128
