To find the area of the path, we'll need to find the area of the space with the path and subtract the area of the inner space.
Total area: (80 + w)(50 + w)
Inner area: 80 x 50
Area of the path: (80 + w)(50 + w) - (80 x 50)
(4000 + 80w + 50w + w^2) - (4000)
4000 + 130w + w^2 - 4000
w^2 + 130w
w(w + 130)
Expression for the total area: (80 + w)(50 + w)
Expression for the area of the path: w(w + 130)
Hope this helps!! :)
Answer:
t=-3.7
Step-by-step explanation:
Let's solve your equation step-by-step.
5(t+3)=−3.5
Step 1: Simplify both sides of the equation.
5(t+3)=−3.5
(5)(t)+(5)(3)=−3.5(Distribute)
5t+15=−3.5
Step 2: Subtract 15 from both sides.
5t+15−15=−3.5−15
5t=−18.5
Step 3: Divide both sides by 5.
5t/5=-18.5/5
t=-3.7
Let x be the number of coins bert had
let y be the number of coins georgia has
x+3 =2y equation 1
x-4 = y equation 2
now, since y=x-4, you can put that in the first equation
it becomes x+3= 2(x-4) right because y is the same thing as x but you can't solve for 2 letters so we have to make them the same.
so your new equation is x+3 = 2(x-4)
expand so you get x+3= 2x -8
then solve for x by putting the x's on one side and the numbers on the other
bring x over --- 3= 2x- 8 - x and subtract the xs to get 3= x-8
then bring the 8 to the other side
3+ 8 = x
x= 11
note: remember! when you're bringing numbers and letters to the other side, you have to reverse the operation: say you have x+1 = 2 --- when bringing the one over to the other side it becomes a -1 ---- x+1= 2-1
so bert has 11 cents.
this question is a little difficult, it takes some practice and it's stuff you'll learn in high school so don't worry too much if you don't get it
Answer:
12/2g + 1
Step-by-step explanation:
I believe it is on simplest form. But as a mixed number it would be 113/2
