Let d = # of dimes

Let q = # of quarters

equation #1: number of coins

    d + q = 1234

equation #2: value of coins

    0.10d + 0.25q = 290.05

Solve #1 for d:

    d=1234-q

Sub #1 into #2 and solve for q:

    0.10d + 0.25q = 290.05

    0.10(1234-q) + 0.25q = 290.05

    123.4 - 0.10q + 0.25q = 290.05

    0.15q =  166.65

    q = 1111

Now go back to d=1234-q and sub in 1111 for q to find d:

    d = 1234 - 1111

    d = 123

1111 quarters and 123 dimes.

How do compute ratios like this like 1/4miles Sebastian runs in 1.6 minutes. How long did it take him to run one mile
Anit [1.1K]
It's easier to write if you convert 1/4 into 0.25.

\frac{0.25mi}{1.6min} =  \frac{1mi}{xmin}

Then you use algebra to find that he ran the mile in 6.4 minutes.

Jeremiah invested money into two different accounts at the same time. The system of inequalities represents the balance of each
olasank [31]

Answer:

1st statement is true.

2nd statement is false.

3rd statement is true.

Step-by-step explanation:

We have been given two inequalities and we are asked to find out whether the given statements are true or false.

y\geq 1.2x+100 represents balance of account A and y\geq 1.23x+50 represents balance of account B.

1. We can see from our inequalities that Jeremiah initially invested $100 in account A and $50 in account B. Therefore, 1st statement is true.

2. The rate at which balance of account A grows is 1.2 and rate for account B is 1.23. Therefore, 2nd statement is false.

3. We can find total amount Jeremiah invested in two accounts by adding initial investment of both accounts, that is 100+50=150 . Therefore, 3rd statement is true.
