Answer:
x=20
Step-by-step explanation:
It all equals 360º and there are two of each angle. So, we can add 5x+5x+(3x+20)+(3x+20)=360º. Subtracted 40 and simplify. So 16x=320.So divide by 16 and you get that x=20.
Answer:
width is 27 yards and length is 123 yards
Step-by-step explanation:
Perimeter of a rectangle is 2(L + W).
If length is 96 more than width, then we know L = 96 + W
Since we also know the perimeter, we can put them into an equation and solve for the length and width:
2(L + W) = P
2(96 + W + W) = 300
96 + 2W = 150
2W = 54
W = 27
Plug this back into L = 96 + W to find the length:
L = 96 + W
L = 96 + 27
L = 123
Therefore, the width is 27 yards and length is 123 yards.
3/4=2/4=5/4
5 divided by 4 or 5/4= 1 1/4
6 1/4+5=6 1/4
hope that helps. It wasn't very clear. so those are the questions I got out of that and those are the answers. Again hope this helps
-5^9 ; (5^3)^-2 <---- Neither of these is equal to 1/(5^9)
3^5 * 3^2; 3^20/3^2 <--- Neither of these is equal to 3^10
4*x; x^-4/x^8 <---- Neither of these is (always) equal to x^4
0 <--- This is the only value not equal to 1, the value of 8^0
