Answer:
![\frac{2}{3}](https://tex.z-dn.net/?f=%5Cfrac%7B2%7D%7B3%7D)
Step-by-step explanation:
The given ratio is ![\frac{18}{27}](https://tex.z-dn.net/?f=%5Cfrac%7B18%7D%7B27%7D)
9 is the common factor of 18 and 27
divide numerator and denominator by 9
![\frac{18/9}{27/9} =\frac{2}{3}](https://tex.z-dn.net/?f=%5Cfrac%7B18%2F9%7D%7B27%2F9%7D%20%3D%5Cfrac%7B2%7D%7B3%7D)
hence
is proportion with ![\frac{18}{27}](https://tex.z-dn.net/?f=%5Cfrac%7B18%7D%7B27%7D)
Answer:
3+x<5x+2
Step-by-step explanation:
the sum of the number 3+xis less than so 3+x<5×x+2
<em>so</em><em> </em><em>final</em><em> </em><em>ans</em><em> </em><em>is</em><em> </em><em><u>3</u></em><em><u>+</u></em><em><u>x</u></em><em><u><</u></em><em><u>5</u></em><em><u>x</u></em><em><u>+</u></em><em><u>2</u></em>
It most common to round to the hundredths place, this is two spaces after the decimal.
So look two spaces right - 0.17. If the third digit (in this case 6) is higher than 5 you round the number up if its not, keep it the same.
"6" is greater than five, so round it to about (or approximately) 0.18.
Refer to the diagram shown below.
w = 6 7/8 in = 6.875 in, the width of each device.
d = 3 1/2 in = 3.50 in, the space between teo devices.
The total space needed is
D = 4(w+d) + w
= 5w + 4d
= 5*6875 + 4*3.5
D = 48.375 in or 48 3/8 in
Answer: 48 3/8 inches or 48.375 inches
