A number (we don’t know the number so I’ll use X) plus five. So we can start the equation of with X+5 then divided by 3=7 so X+5➗3=7 so to solve what X is we can just go in reverse. 7 TIMES 3= 21-5=16 so X=16

Answer:

The required equation is \frac{x+5}{3}=7

The value of x is 16.

Step-by-step explanation:

Consider the provided information.

if a number is increased by 5 and the result is then divided by three,the result is seven.

Let the number is represented by x.

Increase the number by 5: x+5

Now divide the result by 3, and result is seven.

This can be written as:

\frac{x+5}{3}=7

Now solve the equation for x as shown.

\frac{x+5}{3}=7

x+5=21

Subtract 5 from both sides.

x=16

Hence the value of x is 16.

artcher [175]

Answer:

2 oldies and 6 new releases

Step-by-step explanation:

let x equal number of oldies

let y equal number of new releases

2x + 4y = 28

x + y = 8

x = 8 - y

2(8 - y) + 4y = 28

16 - 2y + 4y = 28

2y = 28 - 16

2y = 12

y = 12/2

y = 6

x = 8 - y

x = 8 - 6

x = 2

BabaBlast [244]

Answer:

The minimum number of words left to write is 215

Step-by-step explanation:

Let

w -----> the number of words left to write

we know that

The number of words left to write plus the words written so far must be greater than or equal to 500 words

Remember that the word "at least" means "greater than or equal to"

w+285\geq 500

Solve for w

Subtract 285 both sides

w\geq 500-285\\w\geq 215

The minimum number of words left to write is 215

makkiz [27]

Answer:

<h2>x = -11</h2>

Step-by-step explanation:

In algebra, the goal is always to isolate the variable, so that its value can be determined.

<h3>Step 1: Add x</h3>

6 + x = -5

<h3>Step 2: Subtract 6</h3>

x = -11

<h3>Step 3: Check</h3>

6 = -5 - -11

6 = -5 + 11

6 = 6 ✔

<h3>Step 4: Answer</h3>

x = -11

I'm always happy to help :)
