Answer:

Step-by-step explanation: I don't exactly know. But I know a little Area of sector over total area of circle first. so divided. Then you either multiply or divide the area of the sector by itself and then you divided or multiply it by the reciprocal.  

                                Sorry that's not the best answer.

The question is an illustration of a linear equation

The solution to the equation -\frac 12x + 1 = -x+8 is x =14

<h3>What are linear equations?</h3>

These are equations that have constant rates or slopes

The equation is given as:

-\frac 12x + 1 = -x+8

Collect like terms in the above equation

-\frac 12x + x=8 - 1

Evaluate the like terms

\frac 12x=7

Multiply both sides of the equation by 2

x =14

Hence, the value of x is 14

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.
4.5 cups of lettuce for 1 cup of tomatoes

Explain why 3(5x) is not equivalent to (3*5)(3*x).
Nookie1986 [14]
Wow. Ok, really simple, honestly. Because 3(5x) = 15x. (3*5)(3*x) = 3*5 = 15*3 = 45x. Therefore, 15x and 45x do not correspond to each other at all, meaning that 3(5x) is not equivalent to (3*5)(3*x)!!!
