If I have 48 cards and and gave 10 to my friend and I have 38 left what what fractionbb be is my original number of cards

topjm [15]

Question isn't well formatted :

If I have 48 cards and and gave 10 to my friend and I have 38 left. what fraction of original number of card do I have left.

Answer:

0.7917

Step-by-step explanation:

If I have 48 cards and and gave 10 to my friend and I have 38 left what what fractionbb be is my original number of cards

Given that :

Total number of cards = 48

Number given to friend = 10

Number of cards left = 48 - 10 = 38

Number of cards left / original number of cards

38 / 48

= 0.7917

Solve for x in this inequality. Show all your work and<br> graph your solution.<br> 4(x-3)<2x-4

maw [93]

Answer:

x<4

Step-by-step explanation:

To solve for x in the inequality equation, the terms should be rearranged such that x is on one side and integers are on the other side.

First, expand 4(x-3).

This will obtain:

$4x - 12 < 2x - 4$

Now, shift x terms and integers on each side.

$4x - 2x < - 4 + 12$

After simplifying, it will get:

$2x < 8$

Finally, we can solve for x.

$x < 4$

We can also draw the respective graph (please don't mind my drawings), where the area shaded in green is the range.

Logarithmic and Exponential Forms of Equations In Exercise, write the logarithmic equation as an exponential equation, or vice v

marysya [2.9K]

Answer : The logarithmic equation of given exponential equation is, $\ln (0.0183)=-4$

Step-by-step explanation :

As we are given the exponential equation.

$e^{-4}=0.0183$

Formula used :

The inverse property of logarithm for the expression $\ln e^x$ is:

$\ln e^x=x$

Now we have to determine the logarithmic equation of given exponential equation.

$e^{-4}=0.0183$

Taking natural logarithm both sides as,

$\ln e^{-4}=\ln (0.0183)$

$-4=\ln (0.0183)$

$\ln (0.0183)=-4$

Thus, the logarithmic equation of given exponential equation is, $\ln (0.0183)=-4$
