Your bedroom wall is 171 inches wide. You want to hang two posters, each 42 inches across, with an equal space between each poster and the wall edges. How many inches of space should you leave between the wall edge and poster?

43.5 inches of space should be left between the wall edge and posters.

Step-by-step explanation:

Width of 1 poster = 42 inches

∴ Width of 2 posters = 2 × 42 = 84 in

Remaining width = 171 - 84 = 87 in

Space between wall and poster = 87/2 = 43.5 in

let's solve your equation step-by-step.

4x+2=2x+12

step 1: subtract 2x from both sides.

4x+2−2x=2x+12−2x

2x+2=12

step 2: subtract 2 from both sides.

2x+2−2=12−2

2x=10

step 3: divide both sides by 2.

step-by-step explanation:

irrational, then, just means all the numbers that aren't rational. every integer is a rational number, since each integer n can be written in the form n/1. however, numbers like 1/2, 45454737/2424242, and -3/7 are also rational, since they are fractions whose numerator and denominator are integers.
