Will mark brainliest!<br> Solve!<br> 9x +25+3x = 34 + 54<br> HELP!!!
Salsk061 [2.6K]

Answer:

9x + 25 + 3x = 34 + 54

9x + 3x = 12x

34 + 54 = 88

12x + 25 = 88

      - 25    - 25

12x = 63

D= number of dollars
padilas [110]

<u>Unit rate 4:</u>

The table

d      n

4       1

8       2

16      4

<u>Unit rate 1/4:</u>

Table

d      n

1       4

4       16

16      64

and

The equation n=4d

<u>Unit rate 16:</u>

Equation:

d = 16n

Step-by-step explanation:

The unit in the unit rate is dollars per unit ounces which means that the unit rate calculated by

Unit\ rate = \frac{dollars}{ounces}

So,

The first option is the equation:

d = 16n\\\frac{d}{n} = 16

The unit rate is 16 dollars per ounce

The second option is the table:

d      n

1       4

4       16

16      64

We can take any pair of values of d and n from the table to calculate the unit rate

So taking

d = 1

n=4

Unit\ rate = \frac{d}{n}\\= \frac{1}{4}

The unit rate for table is: 1/4 dollars per ounces

Third option is the equation:

n = 4d

n = 4d

dividing both sides by n

\frac{n}{n} = \frac{4d}{n}\\1 = \frac{4d}{n}

dividing both sides by 4

\frac{1}{4} = \frac{4d}{4n}\\\frac{d}{n} = \frac{1}{4}

the unit rate is 1/4 dollars per ounce

Fourth option is the table:

d      n

4       1

8       2

16      4

We will take any pair of d and n to find the unit rate

So,

Taking

d = 4

n =1

Unit\ rate = \frac{d}{n} \\= \frac{4}{1}\\=4

The unit rate is 4 dollars per unit ounce.
