Answer:
30
Step-by-step explanation:
Answer:
Suppose the number is 4
Square of this number (4 x 4 ) = 16
Divided by 2 = 16/2 = 8
Added to 16 = 8+16 = 24
Step-by-step explanation:
Make an equation
X+X+200=1500
Isolate the variable
2x=1300
X=650
Know that we know what X is, we know that X + 200 will equal the cost of the second appliance
650+850=1500
You split the abs val into a pos and neg soln to write
x–5 = 3 and x–5 = –3
x = 8 and x = 2
