Answer:
27
Step-by-step explanation:
643-166=477
477÷18=26.5
Then, round to the nearest whole.
Which makes it 27 sets.
Lets say x is the smaller number and y is the bigger number.
x + y = 436
x + 134 = y
We can substitute the second equation into the first (substitute x + 134 in for y)
x + (x+134) = 436
2x + 134 = 436
2x = 302
x = 151
We can now plug this back into either formula (i use the second)
151 + 134 = b
b = 285
The 2 numbers are 151 and 285
Answer:
Step-by-step explanation:
First find the slope of the line containing points (5,4) and (-7,9). To find the slope use the formula 
. Putting those values in, you have
Simplify
Then, to find the slope of the line perpendicular to that, find the negative reciprocal.

Answer:</h3>
✔ Angle 3 and 8
✔ Angle 7 and 4
Explanation:
<u>Vertically Opposite Angles are the angles opposite each other when two lines cross. "Vertical" in this case means they share the same Vertex (corner point), not the usual meaning of up-down</u>.
Answer:
A) Gilligan can conclude that triangle ABC and triangle SDC are similar.
B) He can conclude that the distance is longer than the hypotenuses of the triangles.
Step-by-step explanation:
A) This is because they are the same shape and have proportionate sizes.
B) This is because if AB = 90 feet, he knows that the distance will be about the same length as the hypotenuses of the triangles.
