Equation
Let the number = x
(2/3)x + x = 20 Change the x to thirds.
(2/3)x + 3/3x = 20 3/3 = 1 Now combine the like terms.
(2 + 3)/3 = 20 2/3 + 3/3 = 5/3
(5/3) x = 20 Multiply both sides by 3/5
(5/3)*(3/5)x = 20*3/5 Complete the multiplication on the right
x = 4 * 3 Combine
x = 12 Answer
Answer:
100%
Step-by-step explanation:
Perimeter of first garden is given by 2(l+w) where l is length and w is width
Perimeter=2(5+3)=16
The dimensions of second rectangle is doubled hence 10 ft by 6 ft
Perimeter=2(10+6)=32
Change in area will be 32-16=16
Percentage change in area is 16/16*100=100%
The opposite of -7 and 5 twelves is 7 and 5/12
Divide both sides of the equation by - 3
-8x+9y= - 14
-9y+8x=14
simplify the expression
-8x+9y=-14
8x-9y=14
then solve the equation for y
y=-14/9+8/9x
substitute the given value in the ordered pair (x, y)
