The part<span> of the </span>plane 2x+4y+z<span>=8 that lies inside the cylinder x^2+y^2=25. </span>3<span>.) </span>
Percent means parts out of 100
36% =36/100=0.36
'of' means mulitply
27 is 36% of ? translates to
27=0.36 times ?
divide both sides by 0.36
75=?
the number is 75
Answer:
first you need to divide -1.8 from both sides so that would end up like this :
n=30
Step-by-step explanation:
ok so we know that
A + B = 90
we also know that
A - B = 20
There are a lot of ways to solve this, but I think elimination will be best
A + B = 90
+ (A - B = 20)
-----------------------
2A = 110
A = 55
Therefore,
B = 90 - 55 = 35
