Answer:

x=3

Step-by-step explanation:

Step 1-  You Subtract  5 from 17 and get 12 the equation now looks like this

4(x-3)=12

Step 2- You Distrubute  by taking the 4 and multiplying it by the x and 3

4(x)= 4x and 4(-3)=-12  The equation now looks like this  4x-12=12

Step 3- You now add 12 to -12 to cancle it out and you add 12 to the 12 behind the = sign and you get 24 you equation now looks like this 4x=24

Step 4-  You put 4 under 4  and 4 under 12 as shown 4/4 and 12/4 so you get ride of the 4 so only x is left on that side. 12/4= 3. You are left with x=3  So there is your answer.

Zinaida [17]

Answer:

51.544 L  in our tank

Step-by-step explanation:

We have a 13.6 gallon tank

Our conversion factor is 3.79 L = 1 gallon.  We want liters on top since that is where we want to end up

3.79 L /1 gallon is what we want to use

13.6 * 3.79L/1 gallon = 51.544 L  in our tank

Figure A is a scale image of Figure B. What is the value of x?
kari74 [83]

Hey there! :)

Answer:

x = 21 units.

Step-by-step explanation:

Since we know Figure A is just Figure B scaled, we can set up a proportion:

\frac{45}{35}= \frac{27}{x}

Cross multiply to solve for x:

45 · x = 35 · 27

45x = 945

Divide both sides by 45:

x = 21 units.
