Suppose Ken has 25 coins and nickels and dimes only and has a total of a $1.65 how many of each coin does he have?
nikklg [1K]
x-\ number\ of\ nickels\\
y-\ number\ of\ dimes\\\\
x+y=25 \ \ \ | x=25-y\\
0.05x+0.1y=1.65\\\\
0.05(25-y)+0.1y=1.65\\\\
1.25-0.05y+0.1y=1.65\\\\
1.25+0.05y=1.65\ \ \ | subtract\ 1.25\\\\
0.05y=0.4\ \ \ \ \ | divide\ by\ 0.05\\\\
y=8\\\\
x=25-8=17\\\\
There\ are\ 17 \ nickels\ and\ 8\ dimes.

42 /48 in simplest form
zloy xaker [14]

<span>First we need to find the GCF (greatest common factor)</span>

<span>Factors of 42 are:
1, 2, 3, 6, 7, 14, 21, 42</span>

<span>Factors of 48 are:
1, 2, 3, 4, 6, 8, 12, 16, 24, 48</span>

<span>GCF is 6</span>

<span>To simplify you divide numerator and denominator into the GCF</span>

<span>42 ÷ 6 = 7</span>

<span>48 ÷ 6 = 8</span>

<span>42/48 = 7/8</span>

<span>Hope this helps. :)

baherus [9]
x + y = 4,000
0.1x + 0.04y = 352

Product A represents x and product B represents y. The first equation is the total number of items the store owner buys. The second equation is cost per item for both products. The above system of equations can be used to determine how much product A and product B the store owner bought.
