-5(x+7)<-10
-5x-35<-10
+35. +35
-4x<25
both divided by-4
x> -6.25
i flipped the sign because I divided with a negative number. and I hope you can make -6.25 into a fraction, I can't because I don't have a calculator with me :(
X is equal to -15 , I think
2.5 is the answer u welcome
Perimeter= 2l+2w
p= 2(2x)+2(x+3)
Distribute
p=4x+2x+6
Combine like terms
p=6x+6
Final answer: 6x+6
16 model airplanes on his shelf
4 times as many model airplanes as model trains
let's denote the number of model trains as m
So,
m=16×4
m=64
Therefore,there are 64 model trains.
