Can someone help me with this one. I will give Brainliest Answer.

Step-by-step explanation:

okay, what we need to do here is use the distance formula

the distance formula is on the photo, it's kinda hard to type

the salon is at the coordinate (2,13)

and the mall is at (7,1)

so we just have to place these values into the formula

root (2-7)^2 + (13-1)^2

root -5^2+12^2

root 25+144

root 169

13

Fractions and decimals are simply two different ways of expressing a number. A fraction expresses a number in the form of two other numbers, where the top number in the fraction is being divided by the bottom number. ie. if the fraction was written as x/y, then the fraction would be expressing the number x divided by the number y. A decimal, on the other hand is an expression of a number in a more traditional form, in one single line of numbers, with a decimal point preceeding all of it. To convert a fraction to a decimal, we do what the fraction says, in that we divide the top number by the bottom number. For example, the fraction 3/4 (3 quarters) = 0.75, as 3 divided by 4 = 0.75. The reason we use fractions and dont just make everything a decimal, is that sometimes it is easier to calculate something or express a number using a fraction. For example, when working with irrational numbers, the decimal is actually infinite, so it is impossible to write as a decimal and be 100% accurate, however if written as a fraction, it can be expressed exactly. For example the fraction 1/3 = 0.333333 where the 3s continue forever :))
