C is the only one that makes sense
Answer:
x = 28, y = 23
Step-by-step explanation:
5y - 4 and 3y are alternate exterior angles and are supplementary, thus
5y - 4 + 3y = 180
8y - 4 = 180 ( add 4 to both sides )
8y = 184 ( divide both sides by 8 )
y = 23
Thus
3y = 3 × 23 = 69
2x + 13 and 3y are corresponding angles and congruent, thus
2x + 13 = 69 ( subtract 13 from both sides )
2x = 56 ( divide both sides by 2 )
x = 28
Answer:
Therefore a car travelled 288 miles in 4 hours.
Step-by-step explanation:
Given:
The car travels at the rate of 72 mph
Equation is given by
To Find:
How far a car travels in 4 hours = ?
Solution:
Distance covered is equal to the product of speed and time.
We have
.............Given
where,
d = distance
t= time
So at t = 4 hours
Therefore a car travelled 288 miles in 4 hours.
Disance between (x1,y1) and (x2,y2) is
given (-2,5) (3,-4)
D=√106
the distance is √106 units or abotu 10.2
