how long is each side?​


Sagot :

Answer:

38.5, 39.5, 40.5, 41.5

Step-by-step explanation:

x + (x+1) + (x+2) + (x+3) = 160

x + x + 1 + x + 2 + x + 3 = 160

4x + 6 = 160 {combine like terms}

4x = 160 - 6 {transpose 6}

4x/4 = 154/4 {divide both sides by 4 to isolate x}

x= 38.5 {we now have the first term as x}

x + 1= 39.5 {second term}

x + 2 = 40.5 {third term}

x + 3= 41.5 {fourth term}
