3x-2= 4x+9/3 whats the solution

Answers

The answer is x=-5
Hope this helps!

3 x - 2 = 4 x + 9/3

Multiply both sides of the equation by 3

9 x - 6 = 4x + 9

Move variable to the left-hand side and change its sign

9 x - 4 x - 6 = 9

Collect like terms

5 x = 9 + 6

Divide both side of the equation by 5

X = 3

And you answer is X = 3

Thanks :)

Which number are greater than
0.6 0.39 0.07 0.8 0.69 0.17

Let's turn them in to fractions.

$0.6\quad 0.39\quad 0.07\quad 0.8\quad 0.69\quad 0.17\n \n 0.6=\quad \frac { 6 }{ 10 } =\frac { 60 }{ 100 } \n \n 0.39=\frac { 39 }{ 100 } \n \n 0.07=\frac { 7 }{ 100 } \n \n 0.8=\frac { 8 }{ 10 } =\frac { 80 }{ 100 } \n \n 0.69=\frac { 69 }{ 100 } \n \n 0.17=\frac { 17 }{ 100 }$

$\frac { 60 }{ 100 } \quad ,\quad \frac { 39 }{ 100 } \quad ,\quad \frac { 7 }{ 100 } \quad ,\quad \frac { 80 }{ 100 } \quad ,\quad \frac { 69 }{ 100 } \quad ,\quad \frac { 17 }{ 100 } \n \n \frac { 80 }{ 100 } >\frac { 69 }{ 100 } >\frac { 60 }{ 100 } >\frac { 39 }{ 100 } >\frac { 17 }{ 100 } >\frac { 7 }{ 100 }$

Turn back into decimals again.

$0.8>0.69>0.6>0.39>0.17>0.07$

I believe its this because you didnt make enough space...

Mrs. Colen took a trip. She drove 350 miles in 7 hours and 30 minuets. what is her average speed to the nearest tenth of a mile per hour

Answers

diatance travelled by her= 350 miles
amount of time taken by her to travel 350 miles= 7 hrs 30 mins
=450 mins
average speed travelled by her to the nearest tenth of a mile per hour= 450*60/100
=270/10
=27
therefore he travelled 27 miles to the nearest tenth of a mile per hour.

7 hours and 30 minutes is 7.5 hours. Average speed can be found by taking distance and dividing it by time. 350 miles/7.5 hours=46.6666 miles per hour. Rounded to the nearest 10th that is 46.7 mi/hr
