Answer:
The research that i've done says that 3 or 4 are needed.
Step-by-step explanation:
The change that happened from the first half of the equation to the second half was you moved the 9 and the 4c around.
Commutative property of addition allows you to do that. It's what says that 2+3 is the same thing as 3+2
Answer:
Ralph had 600 tomato plants in the beginning.
Step-by-step explanation:
Consider the provided information.
let x is the number of units.
The number of tomato plants in Inessa's garden is 5x
The number of tomato plants in Ralph's garden is 6x
It is given that half of Inessa's tomato plants are taken from her garden and replanted into Ralph's garden.
Therefore,
1/2 × (5x)
After replanted Ralph’s garden had 850 tomato plants.
Therefore,
(1/2)(5x) + 6x = 850
5x + 12x = 1700
17x = 1700
x = 100
The number of tomato plants in Ralph's garden is 6x.
Substitute the value of x in 6x.
6(100)=600
Hence, Ralph had 600 tomato plants in the beginning.
The answer is 4 because it adds 4 to each one.
You can divide this image into 2 different shapes and there are multiple ways to do this. I drew a line straight down from the side that has a length of 6 to divide the image into 2 rectangles
I now have a rectangle that has sides of 7 and 10 and a rectangle that has sides of 4 and 8
A=L*W so A=7*10 which is 70
A=L*W so A=4*8 which is 32
add these areas together to get 102 so "C" is the correct answer
