FIND THE SOLUTION OF EACH EQUATION IF THE REPLACEMENT SETS ARE
Yuliya22 [10]
<span>1) There are no solutions for this equation in the solution set.

2) The solution set is {5} because 15/5 = 3

3) The solution set is {8} because 31 = 3 (8) + 7 \\ 31 = 24 + 7 \\ 31 = 31

4) The solution set is {20} because 20 - 13 = 7

5) The solution set is {66} because 22 x 3 = 66

6) A = 32 - 9(2) \\ A = 32 - 18\\ A = 14

7) 12 \times \frac{5}{15} - 3 = Y \\\\ 12 \times \frac{1}{3} -3 = Y \\\\ 4 -3 = Y \\ Y =1

8) </span>27 + \frac{5}{16} = G\\\\G = \frac{432 + 5}{16}\\\\G = \frac{437}{16}\\\\G = 27 \frac{5}{16}

9) R = \frac{9(6)}{ ( 8 + 1 ) 3}\\\\R = \frac{54}{9(3)} \\\\R = \frac{54}{27}\\\\ R = 2

10) 15,579 + 6,220 + 18,995 = G\\\\ G = 40,794
<span>
11) The solution set is {6, 7} because:
 6 -2 < 6, which is 4 < 6
AND
7 - 2 < 6, which is 5 < 6

12) </span><span>The solution set is {9, 11} because:

Mrs. Jones' classroom aquarium currently has 14 angelfish and 42 neon fish. What is the ratio of neon fish to all the fish in th
Valentin [98]

The ratio of neon fish to all the fish in the aquarium is 3 : 4   .

In the question ,

it is given that

in Mrs. Jone's class room there are angel fish and neon fish

number of angel fish in the aquarium = 14 fish

number of neon fish in the aquarium is = 42 fish

So, the total number of fish in the aquarium = number of angel fish + number neon fish

total number of fish = 14 + 42

= 56

the ratio of neon fish to all the fish in the aquarium is  

= number of neon fish : total number of fish

= 42 : 56

since the ratio is written in simplest form ,

we get

= 6 : 8

= 3 : 4

Therefore , The ratio of neon fish to all the fish in the aquarium is 3 : 4   .

Gina has 5 2/8 feet of silver ribbon and 3 6/8 of gold ribbon. How much more silver ribbon does Gina have than gold ribbon.
Paraphin [41]

Answer: we are simply to subtract the length of the gold ribbon which is 2 4/6 ft from the length of the silver ribbon, 5 2/6 feet. Mathematically,

                               5 2/6 feet - 2 4/6 feet = 8/3 feet

Therefore, Gina has 8/3 feet more of the silver ribbon than the golden ribbon.
