4.50 is the total value. Explanation:

Let d = number of dimes and n = number of nickels.

If the number of dimes is 4 times the number of nickels, then:

d = 4n

Since ""Joey has 10 nickels**,

n = 10

To evaluate the number of dimes, substitute n = 10 into,

d = 4n

d = 4(10)

d = 40 dimes

We set up an equation to reflect the monetary values as follows,

.10d + .05n = "total value"

Substitute d = 40 and Joey's n=10 nickels into the equation.

.10(40) + .05(10) = 4.00 + 0.50 = $4.50 is the total value.

Solve for<br> a. 7a-2b = 5a b
Nookie1986 [14]

For this case we have the following expression:

7a-2b = 5ab

From here, we must clear the value of a.

We then have the following steps:

Place the terms that depend on a on the same side of the equation:

7a - 5ab = 2b

Do common factor "a":

a (7 - 5b) = 2b

Clear the value of "a" by dividing the factor within the parenthesis:

a =\frac{2b}{7-5b}

Answer:

The clear expression for "a" is given by:

a =\frac{2b}{7-5b}

A physician orders 140mg of a medication to give orally. You have 125mg/5mL on hand. What is the correct dose of medication to g
adelina 88 [10]
<h2>Hello!</h2>

The answer is: The correct dose of medication to give is 5.6 mL

<h2>Why?</h2>

To solve this problem we need to establish a relationship between the prescripted medication and the available solution.

Let's write the needed equations to establish the relantionship:

\frac{125mg}{5mL}=1\\\\125mg=5mL

The available solution means 125 mg each 5 mL of solution, so:

\frac{125mg}{5mL}=\frac{140mg}{x}\\\\x*\frac{125mg}{5mL}=140mg\\\\x=140mg*\frac{5ml}{125mg}=\frac{700mg*mL}{125mg}=5.6mL

Hence, the correct dose of medication to give is 5.6 mL of the 125 mg/5mL solution.

Have a nice day!

1. What is the y-inter slope of the graph? What does it mean in terms of this situation?
notka56 [123]

Answer:

1. the y-intercept is 9.5 and it means the starting length of the candle

2. the slope is -1/2 and it means that the candle burns 1/2 an inch every hour

3. it burns an inch every 2 hours, it is 9.5 inches long, so 19 hours it'll take to burn.
