Hi Annabanna11!
You can draw a model for 0.78 by drawing 100 parts and coloring 78 of them! 0.78=78/100=78%
I hope this helps:)
Answer:
(f - g)(x) = 2x - 3
Step-by-step explanation:
(f - g)(x)
= f(x) - g(x)
= 3x - 1 - (x + 2)
= 3x - 1 - x - 2
= 2x - 3
Answer:
A) what did the student do wrong, explain why they are incorrect
B) Demonstrate and explain the correct way to answer the question.
Lauren says that two expressions 3x+4(2x+5) and 6x +5x +5 are equivalent. Simplify the expressions to determine whether or not Lauren is correct. Substitute a value for x to see if she is right.
<u>3x+8x+20 = 6x+5x+5</u>
<u>11x+20 = 11x+5</u>
<u>She is wrong</u>
Students answer: She is correct because both equal 11x +5. I substituted x=2 and got 27 for both
<u>She is wrong because 27 will be the answer for ' 11x+5' only. The correct method should be </u>
<u>x=-15 </u>
