2 1/3 −1.5x=12.3 Solve for x

Mathematics
1 answer:
sergij07 [2.7K]3 years ago
6 0

Answer:

x = -6.6\overline{4}

Step-by-step explanation:

Subtract 2 1/3 from both sides of the equation. 2 1/3 is the same as 2.3333... in decimal form. Now you have:

  • -1.5x = 9.966667

Divide both sides by -1.5 to isolate and solve for x.

  • x = -6.6444...

To show a repeating decimal you would put a line over the repeated number. In this case the line would be over the number 4.

The final answer is x = -6.6\overline{4}.

What is the equation of a line that is perpendicular to y=4x-5 and passes through (-4,6)
lozanna [386]

Answer:

y=-1/4x+5

Step-by-step explanation:

perpendicular lines have slopes that multiply to -1.

Our given line:

y=4x-5

the slope (m) in it is 4. To find the slope of the perpendicular line:

4m=-1

divide by 4

m=-1/4

the slope of the new line is -1/4

here's our equation so far:

y=-1/4x+b

Since the line will pass through the point (-4,6) we can use it to solve for b (y intercept)

so substitute (-4,6) into the equation

6=-1/4(-4)+b

6=1+b

5=b

the y intercept is 5

so our equation is:

y=-1/4x+5

hope this helps! :D
