Answer:
D
Step-by-step explanation:
The sum of a number and twenty-three less than that number" as a mathematical expression is x + (x – 23)
I mean its the only answer with sum and "less than" because that usually means you need to subtract, I hope this helps
Height of sculpture/shadow of sculpture = height of tower/shadow of tower
x/12 = 12/16
16x = 12*12
16x = 144
x = 144/16
x = 9
The sculpture is 9 meters tall
It equals 24 you make the x=7 the multiply 5x7=35+3=38-2x7=24
