Answer:
48 because the additive inverse is what you add to make zero
Answer:7.3 repeating
Step-by-step explanation:
First, since these are right across from each other, they are equal. So (x+16)=(4x-5)
Then you would subtract the 4x from both sides. Making the equation (-3x+16) = (-5)
Subtract the 16 from both sides making it a -3x=-22
To turn it positive, divide everything by negative 1 making the equation 3x=22
Divide 22 by 3 and you get your answer.
Answer:
L=29ft
W=15ft
Step-by-step explanation:
Step one:
given
let the width be x
W=x
L= x+14
P= 88ft
perimeter= 2L+2W
so, substituting our data we have
88=2(x+14)+2x
88=2x+28+2x
collect like terms
88=4x+28
88-28=4x
60=4x
divide both sides by 4
x=60/4
x=15
Step two:
the dimensions are
the width is 15ft
the length= 15+14
L=29ft
The median is the middle number
