Answer:
A) 2(9x - 2)
Step-by-step explanation:
The greatest common factor of 18x and -4 is 2.
B is wrong because 18 is not the greatest common factor of both, since 4 cannot be divided by 18 and result in a whole number.
C is wrong because 18x cannot be divided by 4 to produce a whole number.
D is wrong because it restates the problem in a different way, therefore not factoring it completely. 1 is a common factor of both, but not the greatest.
The number of water stations there are along the 13 1/2 miles long road race according to the task content is; Choice C; 18 water stations.
<h3>What is the number of water stations along the road race?</h3>
It follows from the task content that the number of water stations can be determined as follows;
13 1/2 ÷ 3/4
= 27/2 × 4/3
= 18 water stations.

Answer:
The slope is 5/3
Step-by-step explanation:
(12,0)
(0,-20)
Changes in y is -20-0=-20
Changes in x is 0-12=-12
Rise(y) over run(x) = -20/-12
-5/-3
5/3
The secant of the angle through a point (-5, 3) is -13/5
<h3>Equation of a circle</h3>
The equation of a circle with center (0,0) is given by
x² + y² = r² where r = radius of circle
Now, comparing this to the equation of the given circle x² + y² = 169,
⇒ r² = 169
r = √169
r = 13
<h3>Secant of angle </h3>
The secant of the angle through a point (x, y) is secФ = r/x where
- r = radius of circle and
- x = x-coordinate of point
Now for the point A(-5,12), x = -5.
Since r = 13
secФ = r/x
= 13/-5
= -13/5
So, The secant of the angle through a point (-5, 3) is -13/5

7 miles divided by 4/7 hour
copy dot flip
7 miles * 7/4 hour
49/4 miles/ hour
d = rt
1 miles = 49/4 * t
divide each side by 49/4
1 / (49/4) = t
4/49 =t
it takes 4/49 of an hour
