Answer:

Step-by-step explanation:

The angle, 3x + 14 and the other angle 143 are alternate exterior angles. Alternate exterior angles are congruent to each other if the two lines are parallel. So in this case both the angles are considered congruent from the question assuming that they are congruent.

143 = 3x + 14

129 = 3x

x = 43

Answer:

x = 43

Step-by-step explanation:

The two angles must be congruent for the two lines to be parallel.

$3x+14=143$

subtract 14 from both sides to get

$3x=129$

next divide both sides by three to arrive at the answer

$x=43$

Find the slope of the line going through the points (11,5) and (20,5)

Pani-rosa [81]

So remember the formula for working out the slope:

(y2 - y1) ÷ (x2 - x1)

We already know two points:

(11, 5) and (20, 5) (Remember points are like (x, y)

Therefore y2 = 5 and y1 = 5 and x2 = 20 and x1 = 11

Substitute these into the formula from the start:

(y2 - y1) ÷ (x2 - x1)
(5 - 5) ÷ (20 - 11)
0 ÷ 9

And we can determine the slope is equal to 0 as 0 ÷ 9 = 0

In an orchestra, there are 42 woodwind players to 56 brass is ratio of woodwinds to brass written as a fraction in simplest form

Marrrta [24]

$\frac{42}{56} = \frac{6}{8} = \frac{3}{4}$

I could do that because both numbers are divisible by 7, and then they are divisible by 2. You could also have divided them by 14, but I think it's easier to do and explain this way.
