In order from least to greatest it would be -4/5, -1/4, 7/9. 4/5 is greater than 1/4 and because it is negative it would be a lesser number. After 4/5 is 1/4 because 1/4 is negative so it is less than 7/9. Last would be 7/9 because it is the last one and the greatest number.
Answer is H. p/5 = 8
Given:
1/5 of the plants in a vegetable garden are cucumber plants.
8 cucumber plants.
Find the total number of plants in the vegetable garden.
8 ÷ 1/5 = p
Steps in dividing fractions.
1) Get reciprocal of 2nd fraction. 1/5 is the 2nd fraction. Its reciprocal is 5/1
2) multiply 1st fraction to the reciprocal of the 2nd fraction
8 * 5/1 = p
3) 8*5 = p ⇒ p = 40
p * 1/5 = 8
p/5 = 8
40/5 = 8
8 = 8
Answer: y=-2x+9
Step-by-step: Subtract 2x from 2x+y=9 and get y=-2x+9
(-2x)² + wx - 4 + (x)² + (5x + 6) = (-3x)² - 10
Simplify everything.
(-2x × -2x) + wx - 4 + x² + 5x + 6 = (-3x × -3x) - 10
Add / simplify like terms.
4x² + wx -4 + x² + 5x + 6 = 9x² - 10
Add like terms.
(4x² + x²) + 5x + wx + (-4 + 6) = 9x² - 10
Simplify.
4x² + 5x + wx + 2 = 9x² - 10
Get variables to one side.
So, subtract 2 from both sides.
4x² + 5x + wx = 9x² + (-10 + 2)
Then, subtract 9x² from both sides.
(4x² - 9x²) + 5x + wx = -8
Simplify.
-5x² + 5x + wx = -8

Answer:
gift 1:
424 cm^2
570 cm^3
gift 2:
1420.5 cm^2
3622.5 cm^3
Step-by-step explanation:
We have to calculate the surface area of these gifts in order to know the amount of wrapping paper.
The formula for the surface area is:
A = 2*ab + 2*ac + 2*bc
Gift 1:
A = 2*6*10 + 2*6*9.5 + 2*10*9.5
A = 424 cm^2
That means that gift 1 needs 424 cm^2 of wrapping paper
Gift 2:
A = 2*14*17.25 + 2*14*15 + 2*17.25*15
A = 1420.5 cm^2
That means that gift 2 needs 1420.5 cm^2 of wrapping paper
Now, to calculate the cubic centimeters of packaging peanuts, we calculate the volume, the volume has as formula:
V = a*b*c
Gift 1:
V = 6*10*9.5
V = 570 cm^3
This means that gift 1 needs 570 cm^3 of packaging peanuts
Gift 2:
V = 14*17.25*15
V = 3622.5 cm^3
That means that gift 2 needs 3622.5 cm^3 of packaging peanuts
