Answer: There are 6 bricks in the bag.
Step-by-step explanation:
Convert from mixed number to decimal number. To do it, divide the numerator of the fraction by the denominator and add the result to the whole number part. Then:
![3\frac{3}{4}\ lb=(3+0.75)\ lb=3.75\ lb](https://tex.z-dn.net/?f=3%5Cfrac%7B3%7D%7B4%7D%5C%20lb%3D%283%2B0.75%29%5C%20lb%3D3.75%5C%20lb)
Convert from fraction to decimal number. To do it you need to divide the numerator by the denominator. Then, you get:
![\frac{5}{8}lb=0.625\ lb](https://tex.z-dn.net/?f=%5Cfrac%7B5%7D%7B8%7Dlb%3D0.625%5C%20lb)
Let be "x" the number of bricks in the bag<em>.</em>
<em> </em>Based on the information given in the exercise, you can set up the following proportion:
![\frac{1}{0.625}=\frac{x}{3.75}](https://tex.z-dn.net/?f=%5Cfrac%7B1%7D%7B0.625%7D%3D%5Cfrac%7Bx%7D%7B3.75%7D)
Finally, you must solve for "x" in order to find its value. This is:
![(3.75)(\frac{1}{0.625})=x\\\\x=6](https://tex.z-dn.net/?f=%283.75%29%28%5Cfrac%7B1%7D%7B0.625%7D%29%3Dx%5C%5C%5C%5Cx%3D6)
16 desserts 8+8+8+8+8= 40 so 2/5 of 40 is 16
Hope this help Have a great day.
Answer:
x=-5
Step-by-step explanation:
-4(x-5)=40
-4x+20=40
-4x=40-20
x=20/-4
x=-5
