Just take 30 : 25
divide each to 5 and that’s 6 : 5
Answer:
d=-5
Step-by-step explanation:
5/8(16+24)=6(d-1)+1
distribute 5/8 into (16d+24) and 6 into (d-1)
10d+15=6d-6
subtract 6d on both sides
10d-6d+15=-6
combine like terms
4d+14=-6
subtract 14 on both sides
4d=-20
divide both sides by 4
![\frac{4d}{4} =\frac{-20}{4}](https://tex.z-dn.net/?f=%5Cfrac%7B4d%7D%7B4%7D%20%3D%5Cfrac%7B-20%7D%7B4%7D)
d=-5
hope this helps
Answer:
8
Step-by-step explanation:
Let n represent the number.
<span>.. (3/5)n - 1 = 23 ... three-fifths of a number decreased by one is twenty-three. </span>
<span>Please note that the same English description might be interpreted as </span>
<span>.. (3/5)(n-1) = 23. </span>
<span>We'll use the first interpretation, as it results in the number being an integer. </span>
<span>.. (3/5)n = 24 ... add 1 </span>
<span>.. n = (5/3)*24 ... multiply by 5/3 </span>
<span>.. n = 40 ... carry out the multiplication </span>
<span>The number is 40.</span>
