18 ft= 54 yds.
a square has four equal sides, so 54 times 54 equals 2,916
Your answer is 2,916 square yards
You can set them equal to eachother
x+1=3x-19
solve for X
-3x both sides
-2x+1=-19
-1 both sides
-2x=-20
÷-2 both sides
x=10
y=10+1
y=11
Answer:
x = 20
Step-by-step explanation:
The angles that are marked are called "vertical angles" (I think of a pair of scissors) The two angles are equal to each other. (They get bigger or smaller together, like a pair of scissors)
So, set them equal to each other and solve.
3x + 50 = 6x - 10
SUBTRACT 3x from both sides.
50 = 3x - 10
ADD 10 to both sides.
60 = 3x
DIVIDE both sides by 3.
20 = x
Answer:
Percent decrease of 5%
Step-by-step explanation:
285 - 15 = 270
