Answer:
-7 m + 8 n + 5
Step-by-step explanation:
-4m + 5n - 2 - 3m + 3n + 7
combine like terms
-4m -3m +5n +3n -2+7
-7 m + 8 n + 5
Answer:
x is 64 degrees
Step-by-step explanation:
Since the polygon is a quad we know all the angles add up to 360. So, we can do :
100 + 130 + 66 = 360 - x
296 = 360 - x
Subtract 360 on both sides
-64 = -x
Multiply by negative one on both sides and we get
64 = x
x is 64 degrees
4: No (2 x 4=8+7=16)
5: Yes (-6 x 5= -30 +10=-20)
6: Yes (27 / 3=9 - 7=2)
7: Yes (5 x 4=20 + -8=12)
8: No ( -16/-4= -4 + 3=-1)
9: Yes (3/4 x 20/1=60/4=15)
Answer:
Mark
Step-by-step explanation:
<u>Concepts + Application</u>
The velocity, in this case, is the speed of each friend's car while traveling to Charleston. To find the speed, we divide the number of miles (aka the distance) by the number of hours. The friend with the greatest quotient is the one who traveled at the highest velocity.
<u>Solution</u>
250 ÷ 5 = 50
240 ÷ 4 = 60
135 ÷ 3 = 45
110 ÷ 2 = 55
As you can see, 60 mph is the greatest velocity, so the person who traveled at the highest velocity to Charleston is Mark.
Answer:
Step-by-step explanation:
p(headache) = 0.45
p(headache | taking a vitamin) = 0.15/0.50 = 0.30
The two probabilities <em>are not equal</em>.
