Emily Elizabeth has $1.50 in dimes and nickels. She has 22 coins in all. How many nickels does she have?

Marat540 [252]

Answer:

$14$

Step-by-step explanation:

We can set up the following system of equations:

$\begin{cases}10d+5n=150\\d+n=22\\\end{cases}$ , where $d$ is the number of dimes she has and $n$ is the number of nickels she has.

Multiplying the second equation by -5 and adding both equations lets us isolate and solve for $d$ :

$10d+5n+(-5(d+n))=150+(-5(22)),\\5d=40,\\d=8$

Plugging $d=8$ into any of the two equations will let us solve for $n$ :

$8+n=22,\\n=\fbox{$14$}$ .

Therefore, she has 14 nickels.

A 2-column table with 5 rows. Column 1 is labeled Decimal with entries 0.1 6 repeating, 0.3 repeating, 0.5, x, 0.8 3 repeating.

Sindrei [870]

Answer:

A 2-column table with 5 rows. Column 1 is labeled Decimal with entries 0.1 6 repeating, 0.3 repeating, 0.5, x, 0.8 3 repeating. Column 2 is labeled Fraction with entries one-sixth, two-sixths, three-sixths, four-sixths, five-sixths.

Which best shows how the table can be used to determine the missing value x?

2(two-sixths) equals four-sixths, so 2(0.5) = 1, and x = 1.

4(1-sixth) equals four-sixths, so 4(0.16) = 0.64, and x = 0.64.

Three-sixths plus one-sixth equals four-sixths, so 0.5 + 0.16 = 0.6, and x = 0.6.

Five-sixths plus one-sixth equals four-sixths, so 0.83 + 0.16 = 0.99, and x = 0.9

The equation

ra1l [238]

<h2>Explanation:</h2>

Let's use a trial and improvement method to find this solution.

Step 1. Let's choose x = 8.5

Substituting into the equation:

$(8.5)^2+ 3(8.5) - 94=0? \\ \\ 72.25+25.5-94=0? \\ \\ 3.75\neq 0$

Step 2. Let's choose x = 8.4

Substituting into the equation:

$(8.4)^2+ 3(8.4) - 94=0? \\ \\ 70.56+25.2-94=0? \\ \\ 1.76\neq 0$

Step 3. Let's choose x = 8.3

Substituting into the equation:

$(8.3)^2+ 3(8.3) - 94=0? \\ \\ 68.89+24.9-94=0? \\ \\ -0.21\neq 0$

Since the sign of the equation changes from positive to negative when evaluating from 8.4 to 8.3, then x = 8.3 seems to be a reasonable value. Finally, the solution to 1 decimal place is:

$x=8.3$
