A.
(9/4)/(1/2)
b.
For one pound of tomatoes we would end up doubling the recipe.
The equation would look like this 
2((9/4)/(1/2)
You would distribute and get
(18/4)/(2/2)
which when simplified once is
(9/2)/(1)
but once simplified even more you get your answer.

Which equations are true? Choose all answers that apply: Choose all answers that apply: (Choice A) A -x +0+(- x) = 0−x+0+(−x)=0m
lora16 [44]

Answer:

(B)-x-(-x) =0

Step-by-step explanation:

<u>Option A</u>

Our equation is: -x +0+(- x) = 0

Left Hand Side:

-x +0+(- x) = -x-x=-2x

($Left Hand Side) $-2x\neq 0$ (Right Hand Side)

<u>Option B</u>

Our equation is: -x-(-x) =0

Left Hand Side:

-x-(-x) =-x+x=0

($Left Hand Side) 0 = 0 (Right Hand Side)

Therefore, the equation in Option B is true.

What is the length of the line segment with end points (5, -7) and (5, 11)​
Law Incorporation [45]

Answer:

<h2>18</h2>

Step-by-step explanation:

The formula of a distance between two points:

d=\sqrt{(x_2-x_1)^2+(y_2-y_1)^2}

We have the points (5, -7) and (5, 11). Substitute:

d=\sqrt{(5-5)^2+(11-(-7))^2}=\sqrt{0^2+18^2}=\sqrt{18^2}=18
