https://www.mathhomeworkanswers.org/261319/what-is-marinas-present-age?show=261330#a261330
<p style="text-align: justify;">Let M represent Marina’s age. 4 years ago she was M-4 years old.</p>
<p style="text-align: justify;">Let her daughter’s age now be D. 4 years ago she was D-4 years old.</p>
<p style="text-align: justify;">4 years ago, M-4=3(D-4). M-4=3D-12, M=3D-8.</p>
<p style="text-align: justify;">In 6 years’ time their ages will be M+6 and D+6. M+6=2(D+6). M+6=2D+12, M=2D+6.</p>
<p style="text-align: justify;">So we can equate the two expressions for M: 3D-8=2D+6, D=14.</p>
<p style="text-align: justify;">Therefore M=28+6 or 42-8=34. So Marina is 34 years old.</p>

https://www.mathhomeworkanswers.org/261230/how-many-grams-nh3-are-present-dm3-space-and-643-hg-of-pressure?show=261258#a261258
<p style="text-align:justify">First we need the molecular mass of NH₃=3H+N=3(1.0079)+14.0067=17.0304. If x is the amount in grams the number of moles is x/17.0304. 34.3dm³=0.0343 cubic m.</p>

https://www.mathhomeworkanswers.org/67374/problem-that-multiplication-addition-what-operation-first?show=261210#a261210
sorry to hear your struggling with that.<br />
<br />
a way i was taught to remember the order is BIDMAS (Brackets, Indices, Division, Multiplication, Addition and Subtraction)<br />
<br />
this is really helpful. because the m for multiplication in bidmas comes before the a, you should tackle the multiplication first.<br />

https://www.mathhomeworkanswers.org/260749/expected-value-where-probability-winning-profit-times-wager?show=260796#a260796
<p style="text-align: justify;"><span style="font-size:14px">First we need to define the betting methods.</span></p>
<p style="text-align: justify;"><span style="font-size:14px">METHOD 1: You bet an amount $W, the wager, to win a prize with a value of $V. If you win, you take the prize and your wager is refunded, so your net profit is $V. If you lose, your wager is not refunded, so your net profit is -$W (a loss of $W).</span></p>
<p style="text-align: justify;"><span style="font-size:14px">METHOD 2: This is like Method 1, but whether you win or lose, your wager is not refunded. Your net profit is $V-$W if you win and -$W if you lose.</span></p>
<p style="text-align: justify;"> </p>
<p style="text-align: justify;"><span style="font-size:14px">Now we come to the game. Imagine a room with 8 tables, and each table has a gambler and a banker who takes the bet; and in the centre of the room is a spinning wheel divided into 8 equal segments. One of the segments is the winning segment, but it is not marked. Only when the wheel stops will it be randomly determined by a machine which segment is the winner.</span></p>
<p style="text-align: justify;"><span style="font-size:14px">The 8 tables represent the 8 possible outcomes when the wheel is spun, and the gamblers place their bets. Each table wagers $W for a different segment, so table 1 bets on segment 1, table 2 on segment 2, and so on. Only one table can win and the probability of winning is ⅛, or, in other words, the odds are 8:1 against.</span></p>
<p style="text-align: justify;"><span style="font-size:14px">The wheel is spun. There will be one winning table and 7 losers.</span></p>
<p style="text-align: justify;"><span style="font-size:14px">If table 1 wins (segment 1 is the winner), the gambler under Method 1 wins $V. The net profit is $V, and we’re told that the profit is 4 times the wager, so V=4W. Under Method 2, the net profit is V-W=4W, so V=5W.</span></p>
<p style="text-align: justify;"><span style="font-size:14px">The average profit over all the tables under Method 1 is (4W-7W)/8=-3W/8.</span></p>

If a 1 or 2 comes up, you win $8. Otherwise you lose $2. What is your expected value for this game?
https://www.mathhomeworkanswers.org/260667/gambling-with-friend-which-comes-otherwise-expected-value?show=260685#a260685
<p style="text-align:justify">If you roll the die once only, you have ⅓ probability of winning $8 and ⅔ probability of losing $2. So the odds of winning are 2:1 against. You can expect to lose!</p>
<p style="text-align:justify">If you roll the die twice you have ⅟₉ probability of winning $16, a probability of ⁴⁄₉ of winning $6, and a ⁴⁄₉ probability of losing $6. The odds of winning something (rather than losing) are 5:4 in favour.</p>
<p style="text-align:justify">For 3 rolls:</p>
<p style="text-align:justify">P=⅟₂₇ $24</p>
<p style="text-align:justify">P=²⁄₉ $14</p>
<p style="text-align:justify">P=⁴⁄₉ $4</p>
<p style="text-align:justify">P=⁸⁄₂₇ -$6 Odds of winning something 19:8 in favour. Expect to win!</p>
<p style="text-align:justify">Probability P=⅓ for rolling 1 or 2; P=⅔ for rolling 3-6.</p>
<p style="text-align:justify">Average all outcomes: ⅓(8+(-2)+(-2))=⅓(8-4)=4/3. So the average (expected value) is $4/3=$1.33 approx.</p>

https://www.mathhomeworkanswers.org/259931/what-formula-paying-miles-where-each-mile-pays-more-than-last?show=259933#a259933
<p style="text-align:justify">If the first mile pays $a, then the second and subsequent miles pay $b more than the one before, and we have a+a+b+a+2b+a+3b+...until the amount reaches $50. Since 20 miles are walked the last mile earns a+19b. We take the amount earned in pairs: (a+a+19b)+(a+b+a+18b)+(a+2b+a+17b)+... Each pair adds up to 2a+19b, and there are 10 pairs, so the total is 20a+190b=50. Therefore 2a+19b=5. We can write b=(5-2a)/19. Since b must be positive 2a<5, a<$2.50, that is, payment for the first mile is less than $2.50. If a=$0.22, then b=$0.24. So the payment builds up: 22c for the first mile, 46c for the second mile, 70c for the third mile, 94c for the fourth mile, and so on. </p>
<p style="text-align:justify">There are many possible answers. a=$0.41, b=$0.22; a=$0.60, b=$0.20, etc., all controlled by the equation 2a+19b=5.</p>
