Answer:
65 miles
Step-by-step explanation:
There are two simultaneous equations
. Remeber that v=d/t, 1hour = 60 minutes.
1. 40 = (d+15)/(t+0.5)
2. 50 = d/t
solving: d= 25 miles and t=0.5 hours.
The distance traveled is:
D=d+d+15
D=65 miles
Answer:
B. x = 15, m∠Q = 75°
Step-by-step explanation:
Given:
m∠P = 105°
m∠Q = 
Angles P and Q are supplementary angles
To find value of 
and m∠Q.
Solution:
[Sum of supplementary angles =180°]
[Substitution ∵ m∠P = 105° and m∠Q = ]
Subtracting both sides by 105°.
Dividing both sides by 5.
∴ 
∴ 
Answer:
It will take him 2 hours to eat a whole pizza
Step-by-step explanation:
There are 2 halves in an hour, and if he eats 1/4 of a pizza in half an hour, he will take 2 hours to eat a whole pizza.
You just need to replace the value of x and y in your expression. This gives us :
-12 * 5 - 4 * (-3) + 19 - 3*(-3) = -60 - (-12) + 19 - (-9) = -60 + 12 + 19 + 9 = - 20
