If 48 feet are represented by 12 inches on a scale drawing, then a scale of 1/4 inch represents how many feet? a. 3 foot c. 2 fo

alukav5142 [94]

Hello there!

Math is hard! So we as students, we need to play the smart game with Math in order to find the easiest way to solve the problems. What do I mean? Well as you can see they gave us Fraction which won't be easy! So we will transform the fractions into decimals. So let's get started.

Then a scale of 1/4. Transformed into decimal = Then a scale of 0.25
So instead of using the fraction 1/4, I used its decimal 0.25

So if:

48 feet ......> 12 inches
x feet ........> 0.25 inches

Cross multiply

12 * x = 0.25 * 48

12x = 12
Divide both sides by 12
12x/12 = 12/12

x = 1

The correct answer is option D, 1 foot

I hope this helps! Please let me know if you have any question.

Thanks!

3(2x+5)=3×+4x how di i solve this step by step

BaLLatris [955]

1. distribute the 3 into the parentheses, so you would now have 6x+15=3x+4
2. combine like terms on the right side , so now you have 6x+15=7x
3. subtract the 6 from the left side so it cancels out and also subtract the 6 from the 7 so now you have 15=x
hope this answers your question !
