Answer:

x = 3

Step-by-step explanation:

Substitute x for each answer until you get an answer equal to 2.

3 - 1 = 2

2 - 1 = 2

1 - 1 = 2

The only correct equation is 3 - 1 = 2, so 3 is x.

What is the simplified form of the equation 4/5n - 1/5 = 2/5n ?

Gnoma [55]

we are given

$\frac{4}{5}n -\frac{1}{5} =\frac{2}{5}n$

Firstly , we will multiply both sides by 5

$5*\frac{4}{5}n -5*\frac{1}{5} =5*\frac{2}{5}n$

now, we can simplify it

$4n-1 =2n$

$2n =1$

now, we can solve for n

$n =\frac{1}{2}$ .............Answer

The vagabonds were 200 miles apart at 2 p.M and were headed toward each other if they met at 6 p.M and one was traveling 10 mile

muminat

Answer:

The answer is 200

Step-by-step explanation:

To solve the question given, let us recall the following,

Let r4=200 miles apart

r=50 mph combined speed

Where

2f+10=50

2f=40

f=20

f+10=30

or we can express it in another way,

which is

f x4+(f+10)x 4=200

f x4+f x4+40=200

8f+40=200

Then

8f is =160

f=20

f+10=30

Therefore,

4x 20+4 x 30=200

80+120=200

200=200

Answer CORRECTLY !!!!! Will mark brainliest !!!!

mash [69]

Answer:

g(q) = $\frac{5q}{8}$

Step-by-step explanation:

Given

- 7q + 12r = 3q - 4r

Rearrange making r the subject

Add 7q to both sides

12r = 10q - 4r ( add 4r to both sides )

16r = 10q ( divide both sides by 16 )

r = $\frac{10q}{16}$ = $\frac{5q}{8}$ , thus

g(q) = $\frac{5q}{8}$
