Answer:
35.4x
Step-by-step explanation:
Use Rule of One: x^1 = x
3.54x × 10
Simplify.
the answer is
35.4x
The answer is c.
8x8=64 and 64x8=512
Answer:
.
Step-by-step explanation:
.
We have two equations
One to for the total number of units, to distinct them from 1 bedroom units or 2 bedroom units
x- one bedroom units
y- two bedroom units
x+y= 100
495x+600y= 55,275
We can try to plug in these values for y since it’s asks “how many two bedroom apartments are there” and see if it works out
495x+600(45)= 55,275
495x+27000=55275
-27000 -27000
495x= 28275
/495 /495
x=57.12
There can’t be 57.12 units so A is wrong
495x+600(55)= 55,275
495x+ 33000= 55275
-33000 -33000
495x =22275
/495 /495
x=45
This could work so B is the answer , you could go ahead and try C and B but most likely the answer is B
