You can try by plugging each ordered pair and seeing if the equation comes out true.

(5, 1)

2 * 5 - 1 = 9

That's correct so C is the correct answer.

Caroline, Krutika and Natasha share some sweets in the ratio 1:2:4. Caroline gets 14 sweets.
lisov135 [29]

Answer:

98 sweets

Step-by-step explanation:

Caroline got 14 sweets, ratio for her was 1.

Krutika had twice the bigger ratio than her, which means you have to multipy Carolines' sweets by 2. -> 14*2= 28

And do the same thing for Natasha which gives us the result of 56. 14*4= 56

And finally, you add all of those together and get 14+28+56=98.

Hope I helped! :)

X 5 X6 7 8 A garden table and a bench cost $659 combined. The garden table costs $91 less than the bench. What is the cost of th
Greeley [361]

Answer:

The bench was $375 and the garden table was $284.

Step-by-step explanation:

Let x be the value of the bench, if the table is 91 less than the value of the bench then the equation can be:

x + x-91 = 659

2x -91 = 659

Add 91 to both sides of the equation to isolate the 2x:

2x - 91 + 91 = 659 + 91

2x = 750

Divide both sides by 2 to get 1x:

2x ÷ 2 = 750 ÷ 2

x = 375

This means the bench was $375 and the garden table was $284.

Hope this helps!
