What value can be written on the blank line to make the expressions equivalent? 48 + 54 = ___ ´ (8 + 9)
anonymous
  • anonymous
How simple. First add the two values on the left side and the 2 values inside the parentheses. Then just divide 48+54 by (8+9) and that will be you answer

@Juliannaaaaaa please don't give answers, as we are supposed to help them understand how to do them.

plus it's against the open study guidelines, and the moderators will get really mad.

Which expression is equivalent to the sum of the two areas? 5(7 + 4) 5(7 + 7) 7(5 + 4) 7(4 + 7) Mark this and return
anonymous
  • anonymous
oops not mark this and return
anonymous
  • anonymous
well the area is basically 35+28 so whichever of those equals that would be the answer
anonymous
  • anonymous
sorry about that
anonymous
  • anonymous
The third one
anonymous
  • anonymous
63
anonymous
  • anonymous
and oh
anonymous
  • anonymous
Yes, that is 35 + 28. And like julianna said the only one that equals 63 is the 3rd but please, stop giving answers only.
anonymous
  • anonymous
He's wrong u do not add those two
anonymous
  • anonymous
anonymous
  • anonymous
Whaaaaaaa????????????
anonymous
  • anonymous
Omg, yes you do. The area is 35+28
anonymous
  • anonymous
lol

Next question?

Using the distributive property, an expression equivalent to 34 + 16 is 2(17 + 8). 17(2 + 8). 34 + (4)(4). (2)(17) + (4)(4).
anonymous
  • anonymous
SO basically just first find the value of 34 + 16. That is 50. So which one of them equals 50? HInt, (4)(4) equals 16.
anonymous
  • anonymous
d?
anonymous
  • anonymous
So based on that, the answer is the 3rd one.
anonymous
  • anonymous
Hold on. This is distributive property. I did not see that.
anonymous
  • anonymous
ok...
anonymous
  • anonymous
It would have to be A or B and once you solve it, you get A
anonymous
  • anonymous
yeah this is distributive property
anonymous
  • anonymous
all of the questions are about distributive property
anonymous
  • anonymous
The other ones are right, lets move on

Aida applied the distributive property to write the equivalent expressions below. 15 + 21 = 3(4 + 8) What is Aida’s error? Aida used 3 as the factor, which is not common to 15 and 21. Aida did not correctly divide by the common factor to get (4 + 8). Aida did not apply the correct operations to the expressions. Aida wrote two expressions that are not equivalent.
anonymous
  • anonymous
Well here, they do equal each other, but i guess it means that she did not divide by the correct common factor, because if you look at every one of them you can eliminate everything but B
anonymous
  • anonymous
b is the answer, thx
anonymous

Sari applied the distributive property using the greatest common factor to determine the expression that is equivalent to 84 + 40. Her work is shown below. Factors of 84: 1, 2, 3, 4, 6, 7, 12, 14, 21, 28, 42, 84 Factors of 40: 1, 2, 4, 5, 8, 10, 20, 40 84 + 40 = 2(42 + 20) What statement best describes Sari’s error? Sari did not use correct factors for 84 in the equation. Sari did not use correct factors for 40 in the equation. Sari did not use two equivalent expressions in the equation. Sari did not use the greatest common factor in the equation.
anonymous
  • anonymous
okay, the answer is pretty obvious as there are bigger factors than 2. So that means?
anonymous
  • anonymous
its not a or b??????????
anonymous
  • anonymous
Yes, it is D
anonymous
  • anonymous
:D
anonymous
  • anonymous
Do you understand the distributive property and GCF? no offense but for me this is some easy math.
anonymous
  • anonymous
i suck at math, like i can bareley answer 2+2, lol, but im REALLY REALLY BAD AT MATH
anonymous
  • anonymous
..... i have no comment.
anonymous

next question?
anonymous
  • anonymous
i know im bad, LOL, but not really a little exageration
anonymous

Using the distributive property, an expression equivalent to 48 + 30 is 5(6 + 8). (6)(8) + (3)(10). (3)(16) + (6)(5). 6(8 + 5).
anonymous
  • anonymous
you there?
anonymous
  • anonymous
Sorry i was doing something. SO again it has to be either a or d, so which equals 48+30?
anonymous
  • anonymous
d
anonymous
  • anonymous
Yes
anonymous
  • anonymous
YAY

Jimmy applied the distributive property to write the equation below. 24 + 6 = 6(4 + 2) What is Jimmy’s error? Jimmy did not write the common factor in the correct place. Jimmy used 6 as the factor, which is not common to 24 and 6. Jimmy did not apply the correct operations to the expressions. Jimmy wrote two expressions that are not equivalent.
anonymous
  • anonymous
you there???
