Solve for the value of x in this equation: 146=2+7x+5x

Answers

Answer 1

Answer:

x=12

Step-by-step explanation:

First combine like terms

146=2+12x

Then I like to put it into y=mx+b form.

146=12x+2

Next you subtract 2 from both sides.

146-2=12x+2-2

144=12x

Finally you divide 12 on both sides and in the end you get x=12. Hope this helps.

Answer 2
the answer is x = 12

What distance would you travel in 2.5 hours if you are biking with the speed of 6.3 mph?

Answers

Answer:

15.75 miles

Step-by-step explanation:

Step one:

given

time= 2.5 hours

speed= 6.3mph

Step two:

Required

Distance

we are given the speed in miles per hour, hence the distance will be in miles

we also know that the expression relating speed, distance and time is given as

speed= distance/time

thus

distance= speed*time

distance= 6.3*2.5

distance= 15.75 miles

By using expression for the speed, distance traveled by me in 2.5 hours will be  

Given in the question,

Speed = 6.3 mphTime for travelling = 2.4 hours

Expression for the speed of an object is given by,

Speed = [tex]\frac{\text{Distance}}{\text{Time}}[/tex]

Therefore, Distance = Speed × Time

By substituting the values of speed and the time in the expression,

Distance traveled = 6.3 × 2.5

                              =  15.75 miles

   Therefore, distance traveled by me in 2.5 hours will be 15.75 miles.

add like terms

30 + 7k = 100

100-30 = 70

70 divided by 7k = 10

k = 10

4. add the z's together

2z - 6 -2 = -10

+ 6 + 2

-10 will be -2 now since we dragged the -6 and -2 to the other side

2z = -2

z = -1

5. 3.2x - 1.7x = 1.5x

1.5x + 5.5 = 10

10 would be 4.5 since we dragged 5.5 to the other side so it would be 10 - 5.5

3.2x = 5.5

x = 1.71875

Here is a system of equations:
-7x + 3y = -65
-7x + 10y = -135
Write an equation that results from subtracting the two equations.

Answers

Answer:

y = -10

Step-by-step explanation:

(-7x+3y) - (-7x +10y) =-65 -(-135)

-7x + 3y + 7x -10y = 70

-7y = 70

y = -10

The equation that results from subtracting - 7x + 3y = - 65 and

- 7x + 10y = - 135 is 7y = - 70.

What are simultaneous equations?

We know two simultaneous equations have a unique solution when they intersect at a point,

when they are parallel they have no solution and when they are coinciding they have an infinite no. of solutions.

Given, a system of equations - 7x + 3y = - 65 and - 7x + 10y = - 135.

Subtracting the first equation from the second we get,

   - 7x + 10y = - 135

(-) - 7x + 3y =    - 65

_________________

Negative sign gets distributed

   - 7x + 10y = - 135

  + 7x - 3y =   + 65

_________________

            7y =   - 70

              y =   - 70/7

              y =  - 10.

So, the value of x is -7x +10×(-10) = - 135.

- 7x - 100 = - 135.

- 7x = - 135 + 100.

- 7x = - 35.

x = 7.
