Answer:
k
Step-by-step explanation:
First of all, you dont tell me what to do. I didnt ask for your attitude sir.
Why dont U hurry up and keep your mouth shut!
The standard form: ax + by = c
and your equation is: -2x + 3y = - 5 (Yes this is written in standard form)
Speed used by Emily from home to post office is:
speed=(distance)/(time)
distance=3/4 miles
time=8:29:30-8:25=4 min 30 sec=4.5 min
thus speed=(0.75)/4.5=1/6 mile/min
The remaining distance from Post office to school:
3.42-0.75=2.67 miles
time taken to reach to school assuming that Emily will move with the same speed is:
time=2.67/(1/6)=16.02 min=16 min 1.2 seconds
time Emily will reach school is:
8:29:30+0:16:1.2
=8:45:31 a.m
This means that she will reach on time
Answer:
Step-by-step explanation:
Note that it is a triangle's measurement = 180°
You are solving for x. Set all the angles = 180°
73 + 8x + 4 + 8y - 7 = 180
Simplify. Combine like terms
73 + 4 - 7 + 8x + 8y = 180
70 + 8x + 8y = 180
Solve for x. Subtract 8y and 70 from both sides
8x + 8y (-8y) + 70 (-70) = 180 (-8y) - (70)
8x = 180 - 70 - 8y
8x = 110 - 8y
Isolate the x. Divide 8 from both sides
(8x)/8 = (110 - 8y)/8
x = 13.75 - y
x = 13.75 - y is your equation you will use to solve for x when you know what y is.
