Answer:

D. right angle

Step-by-step explanation:

I think D is because

right angle is a an angle of exactly 90°

*adjacent angle is two angles with a common vertex, sharing a common side and no overlap

*supplementary angle is two angle, the sum of who's measure is 180

* vertical angle is two angle who's sides form two pairs of opposite rays (straight line)

3. x + 4y = 30<br> x - 2y = 0

kolbaska11 [484]

Answer:

Step-by-step explanation:

Given that:

x + 4y = 30

x - 2y = 0

Subtracting both equations:

6y = 30

y = 30/6

y = 5

Putting in above equation

x + 4(5) = 30

x + 20 = 30

x = 10

Simon drove for 2 1/2 hours to get from his house to the beach. Simon averaged 55 miles per hour on the trip. What is the distan

Sav [38]

Answer:

The distance from Simon's house to the beach is 137.5 miles

Step-by-step explanation:

we know that

The speed is equal to the ratio of the distance and the time

Let

s ----> the speed in mph

x ----> the distance in miles

y ---> the time in hours

$s=\frac{x}{y}$

we have

$s=55\ mi/h$

$y=2\frac{1}{2}\ h=\frac{2*2+1}{2}=\frac{5}{2}\ h$

substitute in the formula and solve for x

$55=\frac{x}{(5/2)}$

$x=(5/2)55\\x=137.5\ mi$
