The first one is number 2 the second one is 185.(could you also say what is in the drop down menu for the third one. The last one is Part A is 376 and part B is 1,3,4.Hoped it helped a bit :)
First attachment: Indication words: each, gives, left. > Each indicates multiplication > left and gives indicate subtraction.
''5 packs obtains 4 cards each. 3 cards are given away,'' translates to 5 * 4 - 3
Therefore B = 5 * 4 - 3
Second attachment: Indication words: more, gives. > More signifies addition > Gives signifies subtraction.
The equation would be 229 + 35 - 149 = ?
Use PEMDAS. Note that you do addition first since it's before subtraction when we read this equation question left to right. 229 + 35 - 149 = ? ⇒(229 + 35) - 149 = ? ⇒ 264 - 149 = 115; ? is 115
Answer: 115
Third attachment: I cannot answer; I don't know the choices in the choose boxes.
Fourth attachment: You are incorrect for Part A. Raising 9 dollars EACH (*) day for a week (7 days) translates to, in mathematical terms, 9 * 7. 9 multiplied by 7 equals 63. The goal was to get to 439 dollars. If they have 63, how much MORE (+) do they need? To solve this, we do inverse operations of addition which is subtraction. Take 439 and subtract it by 63. 439 - 63 = 376. Check our work: 376 + 63 = 439? Yes.
In conclusion the answer for Part A is A; $376.
Part B - Answer 1: 9 book covers (9 * 8 = 72 ) + 1 calculator (1 * 9 = 9) = 81. Do not check this off because the result is not exactly 80. Answer 2: 1 binder (1 * 4=4) + 8 calculators (8 * 9= 72) = 76. Do not check this off because the result is not exactly 80. Answer 3: 1 book cover (1 * 8 = 8) + 8 calculators (8 * 9 = 72) = 80. Check this because the result is exactly 80. Answer 4: 7 calculators (7 * 9 = 63) + 1 stapler (1 * 17) = 80. Check this because the result is exactly 80. Answer 3 and 4 are correct in summary.
Given and , then . This shifts the graph of the parent function 2 units to the left. Thus, the domain of the function is , making none of the above true.
