Answer:
Step-by-step explanation:
let pickle bought by alexa =x
then according to given condition ,
pickle bought by Tom= (1/3) of Alexa
pickle bought by Tom= (1/3) x
hence also given
totall pickle cost = Tom cost + alexa cost = 56p
(1/3)x+x=56
taking L.C.M
(4/3)x=56
x=56*3/4
x=42 p
so it means,
<h2>
Alexa cost = x = 42p</h2><h2>
Tom cost = (1/3)x= (1/3)*42 = 14 p</h2>
IT IS 2X IF U NEED SOME ELSE TELL ME
So you have to subtract 115 from 15. Then you divide that number by 5 for each relative. That should give you your answer....$20
Hi there!

We are given the equation:
x² - 2y = 7
To verify if each ordered pair is apart of the function, we can plug in their respective x and y values:
1. (5)² - 2(8) = 7
25 - 16 = 9 ≠ 7. This is NOT correct.
2. (-1)² - 2(-3) = 7
1 + 6 = 7. This is correct.
3. (-4)² - 2(-11.5) = 7
16 + 23 = 39 ≠ 7. This is NOT correct.
4. (1.2)² - 2(-2.78) = 7
1.44 +5.56 = 7. This is correct.
Thus, only 1 and 4 are the correct answers.
20miles increased by 30%=new mileage added
20x.3= 6
6 miles more than his previous distance so...
6+20= 26
NOTE you can also use 1.3 instead of .3 as the percent to get the answer with out addition.
