Answer:
x = 70, y = 90
Step-by-step explanation:
A straight line is equal to 180 degrees, so if 180 is split between 110 and x. Subtract the 110 to get the rest. 180-110 = 70.
All sides in a quadrilateral add up to 360 degrees, add all of the remaining angles (112+88+70) to get 270. 360-270 = 90 degrees. Y is 90 degrees.
The first step is:
- determine how far from the house is young equestrian at noon.
2 x 10 = 20 miles
15 t = 20 + 10 t
15 t - 10 t = 20
5 t = 20
t = 20 : 5
t = 4 hours
Answer: at 4:00 PM.
3: m= 2, -3
4: x= -1, 5/2
5: x= -1, -3
6: x= 5/2, -4
X+y=10, x=10-y
4(10-y)+6y=332
solve the next parts yourself
Substitution is to use one variable to express another variable in order to eliminate one variable in the original equation
