1. emmanuel bought 28 lb of potting soil this week. this amount is 4 lb more than twice the amount of potting soil he bought last week. answer the following questions to find the number of pounds of soil emmanuel purchased last week. (a) what is the unknown information? (b) let p represent the unknown information. write an equation to model the problem. (c) which number, 10, 11, or 12, will solve the equation in part (b)? show your work. (d) how many pounds of potting soil did emmanuel buy last week?

Equation:

(28     -     4) / 2    =     p

Let's solve your equation step-by-step.

28     -   4/2     =    p

Step 1: Simplify both sides of the equation.

12         =       p

Step 2: Flip the equation.

p          =      12

      >    p       =       12 Pounds of potting soil Emmanuel would have gotten last week

When Graph:

28   -   4/2    =    p

Intersection Points >     (12,     12 )

Hope that helps                                     : )

answer

d. 10

explanation

the distance from point y to wx is the height of the triangle.

using pythagoras theorem,

group similar terms to get,

this implies that,

take positive square root of both sides to get,

this implies that,
