Llana [10]

Hey there!

First, let's multiply each side of the equation by 3 to get rid of the fraction \frac{2}{3}.

9 + 2x = \frac{6}{5}

Next we can multiply each side of the equation by 5 to get rid of the fraction \frac{6}{5}.

45 + 10x = 6

There's your answer!

Hope this helps!

Find the exponential function that satisfies the given conditions:
Nady [450]

Answer:

f(t) = 66·0.995^t

Step-by-step explanation:

You can try t=0 and t=1 in each of the formulas to see which one gives values of 66 and 0.5% less than 66, or 65.67.

The first function has an initial value of 0.5, so is not correct.

The second function gives f(1) = 99, so is not correct.

The third function gives f(1) = 65.67, so is correct.

The fourth function gives f(1) = 66.33, so is not correct.

_____

You can realize that the multiplier will be 0.5% less than 100%, so will be 99.5% = 0.995. This number shows up only in the third selection.

Dollar is worth three and 3 1/2 kruneros. What is the value of 43 3/4 kruneros?
Korvikt [17]

<em><u>Question:</u></em>

One dollar is worth 3 1/2 kruneros. What is the value of 43 3/4 kruneros?

<em><u>Answer:</u></em>

The value of 43\frac{3}{4} kruneros is 12.5 dollars

<em><u>Solution:</u></em>

Given that,

Dollar is worth three and 3 1/2 kruneros

Which means,

1 \text{ dollar } = 3\frac{1}{2} \text{ kruneros }\\\\1 \text{ dollar } = 3.5 \text{ kruneros }

We have to find the value of 43\frac{3}{4} kruneros

Let us convert the mixed fractions to improper fractions

Multiply the whole number part by the fraction's denominator.

Add that to the numerator.

Then write the result on top of the denominator.

43\frac{3}{4} = \frac{43 \times 4 + 3}{4} = \frac{175}{4} = 43.75

So we have to find the value of 43.75 kruneros

Let "x" be the value of 43.75 kruneros

Then,

1 dollar = 3.5 kruneros

x dollar = 43.75 kruneros

This forms a proportion and we can solve the sum by cross multiply

1 \times 43.75 = x \times 3.5\\\\x = \frac{43.75}{3.5}\\\\x = 12.5

Thus value of 43\frac{3}{4} kruneros is 12.5 dollars
