How much money will you have if you started with $30 and put it in an account that earned 11% every year for 5 years?

1 answer:

6 0

At the end of each year, the amount is (1 + 11%) = 1.11 times the amount at the beginning of the year. When that multiplier is applied 5 times, the result is
$30 * 1.11^5 ≈ $50.55

Solving systems of equations using substitution/elimination

Step-by-step explanation:

Step 1: Define systems

5x - 2y = 9

3x + 4y = -5

Step 2: Rewrite systems

10x - 4y = 18

3x + 4y = -5

Step 3: Solve for x

Add to equations together: 13x = 13
Divide 13 on both sides: x = 1

Step 4: Solve for y

Define: 3x + 4y = -5
Substitute in x: 3(1) + 4y = -5
Multiply: 3 + 4y = -5
Isolate y term: 4y = -8
Isolate y: y = -2

And we have our final answer!

Solve for x 20 points

torisob [31]

Answer:

x = 21 units

Step-by-step explanation:

The tangent squared is equal to the secant's total length multiplied by the secant's length without the part inside the circle.

So here, that will look like: 36² = 27 * (27 + x)

Expansion and multiplication gives us: 1296 = 729 + 27x

Subtract from both sides: 567 = 27x

Divide from both sides: x = 21.

Three less than the product of six and x is 7

podryga [215]

the equation is:

6x - 3 = 7

Not sure if that's what you are asking?

If you solve for x that is:

x = 5/3
