If Laura bikes x miles to and from her friend's house each day, what expression can be used to calculate the total distance she travels in a week? x / 7
x + 7
7x
7 – x

7x

Step-by-step explanation:

This is because x represents how many miles she rides each day, so you need to multiply x by the 7 days in a week

this is false ^.^ lol

b. 18

step-by-step explanation:

so the equation for this is:

ab^2=ac⋅ad

ab being the top length of 6 and ac being the length of 2 and ad being the length of x. let's plug into the equation:

6^2 = 2x

now lets just solve for x:

36 = 2x

18 = x

i hope that !
