Over a half-mile stretch of road, there are 7 evenly spaced street signs. Find the distance between each street sign.

We know that:

Over a half-mile stretch of road, there are 7 evenly spaced street signs.

If we assume that there is a sign right at the beginning and another right at the end, then the distance between each sign will be equal to the total distance divided by the total number of signs minus one because the distance is measured in pairs of consecutive signs, if we have 7 signs, then we will have 6 pairs of consecutive ones ( 1st and 2nd, 2nd and 3rd, 3rd and 4th, ...)

(0.5mi)/6 = 0.83... mi

So, rounding to the second decimal after the decimal point, the distance between each sign is 0.83 miles.

to find the perimeter of the rectangle this is the expression:

x-9+x-9+3x-4+3x-4=138

if we simplify it:

8x-26=138

remember, 138 is what it all adds up to

the length is 11.5cm

the width is 57.5cm

the area is 661.25cm^2
