Use proportional math. 12 is to $36 as 8 is to ___. Or 12/36 is to 8/X.
36 x 8 = 288 divided by 8 = 24

Three less than three times a number is 5/6. What is one more than twice the number
dimaraw [331]

Answer:

32/9

Step-by-step explanation:

Translating the word problem into a symbolic equation yields:

3n - 3 = 5/6

Solve this for the number (n):

Multiplying both sides of this equation by 6 clears out the fraction term:

18n - 18 = 5

Adding 18 to both sides isolates 18n:    18n = 23

Then the number is n = 23/18, and:

one more than twice this number n is 2(23/18) + 1, or:

46/18 + 18/18, or 64/18, or (reducing this result)

32/9

Write an equivalent expression 3c + 7 + 12d - 6d + 4c + 5 = ?c + ?d + ?​
mars1129 [50]

Answer:7c +6d +12

Step-by-step explanation:3c + 7 + 12d - 6d + 4c + 5 = ?c + ?d + ?​

                                       3c + 4c  +12d - 6d +7 +5

                                       = 7c +6d +12

You combine like terms which are 3c and 4c which gives you 7c .Next you combine 12d and 6d but this time u need to subtract since it has subtact sign in between 12d and 6d which gives you 6d.After that you combine 7 and 5 which u get 12 .Lastly you put all of the tersm together which are 7c and 6d and 12 which get you 7c +6d +12  as your equivalent expression.
