Answer: r=14
Step-by-step explanation:
because they are vertical angles
7r+6=8r-8
solving for r you get
r=14
Parallel lines have the same gradient.
The equations are either in the form y = mx+b (m is the gradient)
or in general form ax + by + c = 0 (-a/b)
The gradient of y = 2x - 4 is 2.
The answer is B (gradient = -4/-2 = 2)
Answer:
13 and three-fourths inches
Step-by-step explanation:
The map distance can be found using a proportion with the map scale.
__
map distance / (1100 mi) = (1 in) / (80 mi)
map distance = (1100×1)/80 in = 13 3/4 in . . . multiply by 1100 mi; cancel mi
The trip will be about 13 3/4 inches on the map.
