Answer:
not really sure what you are doing buta rhombus is just a sideways diamond
Step-by-step explanation:
Answer:
91 + 125 + 92 +(3x-5) + (4x- 8)= 540
308 +3x -5 +4x -8 =540
7x - 295 = 540
7x = 540 -295
7x = 245
x = 245/7
x = 35
Step-by-step explanation:
<span>16 walls in 40 hours
3 walls in h hours
16/40 = 3/h
16h = 40(3)
16h = 120
h=120/16
h=7.5
answer: </span><span>3 walls in 7.5 hours</span>
