I think that I have the correct answer but it just seem so simple could someone double check me please. What is the perimeter of a triangle whose sides are the length of 4x,4x+7, and x=
Thank you in advance
The other question I need to right an equation and find the solution to the problem you have three buildings with the total height of 1800 ft. Building 1 is 4 times higher than building 2 and building 3 is 300ft higher than building 2. So I need the equation I would use to solve the problem
Please help thanks again anyone.
I had X= building one
x times 4 equals building 2
x+300 = building 3
So
x+(x4)+(x+300)=1800 feet
I tried combinding like terms to solve Can you tell me if I'm on the right track
3x+300 x 4=1800
minus 300 from both sides divid by 4 then by 3 but I get 125
the buildings should be
1=250 2=1000 3=550
I cant figure out what I'm doing wrong
i don't understand what you did in the line i highlighted red
your x should represent building 2 not 1, you are reading things backwards.
anyway, we have:
x + 4x + 300 + x = 1800
=> 6x + 300 = 1800
=> 6x = 1500
=> x = 250
Thus, building 1 = 1000, building 2 = 250, building 3 = 550
