Write a number with one decimal place,that is bigger than 6 4/5 but smaller than 7 how can I solve this

statuscvo [17]

Hello!

The easiest way to solve this would be to convert 6 4/5 to a decimal. We know that to convert a fraction to a decimal, we must divide the numerator by the denominator.

4 / 5 = 0.8

0.8 + 6 = 6.8

So, 6 4/5 is 6.8 as a decimal.

See how it's easier now that we've converted the mixed number to a decimal?

There could be many numbers between 6.8 and 7. Some examples are:

6.81, 6.82, 6.83, 6.9, etc.

SOMEONE HELP ???? Select steps that could be used to solve the equation 1+ 3x = -x+4

Alex

Answer:

a) add x , subtract 1 and divide by 4

The solution of given equation $x = \frac{3}{4}$

Step-by-step explanation:

Given equation 1+3 x = -x +4

Add 'x' on both sides , we get

1 + 3 x + x = - x + x +4

1 + 4 x = 4

Subtract '1' on both sides , we get

1+4 x -1 = 4 -1

4 x = 3

Dividing '4' on both sides, we get

$\frac{4x}{4} = \frac{3}{4}$

$x = \frac{3}{4}$

Final answer:-

The solution of given equation $x = \frac{3}{4}$
