Step-by-step explanation:

equation: m-3n=16

Solution,

or, m - 3n = 16

or, m - 3×8 = 16

or, m - 24 = 16

or, m = 16 + 24

or, m = 40

Therefore, the value of m is '40'

Which of the following equations represents a line that is parallel to the line 3x - 2y = 12
sveticcg [70]

Answer:

Step-by-step explanation:

12=3x-2y

2y+12=3x

2y=3x-12

y=(3x-12)/2

y=mx+b

To be parallel to the line above our line must have the same slope or m. The above line has a slope of 3/2 or 1.5 so the parallel line will be

y=1.5x+b, using point (7,10) we can solve for the y intercept or b

10=1.5(7)+b

10=10.5+b

b=-0.5 so our line is

y=1.5x-0.5

21 feet to 8 yards write a ratio as a fraction in simplest form without any units
Dmitriy789 [7]

We know, 3 feet = 1 yard.

We have to convert feet to yards to calculate the ratio so that the final answer doesn't have any unit.

Therefore, 21 feet = \frac{21 feet}{3 feet}yards = 7 yards

Thus, the ratio

\frac{21feet}{8yards} =\frac{7yards}{8yards} =\frac{7}{8}

The fraction \frac{7}{8} is already in its simplest form.

Therefore, the given ratio as a fraction in the simplest form without any units is \frac{7}{8}

Construct a line that is perpendicular to
kodGreya [7K]
1) The line will need to be vertical down the point of x, meaning draw a line down point x. Perpendicular lines look similar to t’s
2.) Same thing, just draw a line through point O and the line. They should look similar to t’s
Hope this helped!! I understand math can get really hard, soon it’ll all be over :)
