There are no numbers in the thousandths place so it is assumed to be zero and 24.85 is already rounded to the nearest one-hundredth...
It equals -6 or -2 you do the two eqasions. x=-2-4 or x=2-4.
You will have to divide 140 by 8 and it will give u P you already know R equals 8
Answer:
Kindly check explanation
Step-by-step explanation:
1) shape = square
Side length = 6.5 in
Area of square = (side length)²
Area = 6.5^2 = 42.25 in²
Perimeter of square = 4 * side length = 4 * 6.5 = 26 in
2.) shape = rectangle
Dimension = 1.1 by 2.8m
Area of rectangle = Length * width = 1.1 * 2.8 = 3.08 m²
Perimeter of rectangle = 2(length + Width)
Perimeter = 2(1.1 + 2.8) = 2(3.9) = 7.8 m
3.) triangle
Base = 4.5 ; height = 6.5 ; hypotenus = 7.9 cm
Area = 0.5bh = 0.5 * 4.5 * 6.5 = 14.625 cm²
Perimeter = (4.5 + 6.5 + 7.9) cm = 18.9 cm
Answer:
x= 8 / 5
Step-by-step explanation:
Step 1: Simplify both sides of the equation.
20(x+2)+31=5(5x+10)+13
(20)(x)+(20)(2)+31=(5)(5x)+(5)(10)+13(Distribute)
20x+40+31=25x+50+13
(20x)+(40+31)=(25x)+(50+13)(Combine Like Terms)
20x+71=25x+63
20x+71=25x+63
Step 2: Subtract 25x from both sides.
20x+71−25x=25x+63−25x
−5x+71=63
Step 3: Subtract 71 from both sides.
−5x+71−71=63−71
−5x=−8
Step 4: Divide both sides by -5.
−5x / -5 = -8 / -5
x= 8 / 5
