Jack, Sarah and Elena have to find which of the expressions are equivalent to each other. Expression A: 5x - 2x - 3
Expression B: 15x - 3
Expression C: 2x + x - 3
Elena says all three are equivalent because when she substitutes x with zero, all expressions equal -3.
ELENA IS INCORRECT **Answer the following on a loose leaf sheet of paper.**
• Identify the error in Elena's thinking.
Determine which of the expressions are equivalent.
Explain and show your process in determining which expressions are equivalent.

answer: the answer is 5/22

step-by-step explanation: if you subtract 17 from 22 the answer is 5 therefore the remainder of students are female

connie < felicia < stew

step-by-step explanation:

stew:

we need to find the slope

m = (y2-y1)/ (x2-x1)

    = (2650-795)/(10-3)

    = 1855/7

connie:

we need to find the slope

m = (y2-y1)/ (x2-x1)

we have two points (0,0) and (4,800)

m = (800-0)/(4-0)

  m = 800/4

felicia:

260 words per minute

200< 260 < 265

connie < felicia < stew
