Answer:
b) 60 is the distance in miles that must be travelled to get to Michael's grandparents' house
Step-by-step explanation:
hello
at the speed of x mph in 1 hour he travels x miles
so in 60/x hour he travels 60 miles
so 60 is the distance in miles that must be travelled to get to Michael's grandparents' house
another way to see it is as below
distance = vitesse * time so
time = distance / vitesse
hope this helps
Answer:
Step-by-step explanation:
7d – 8 = 3d + 8
7d - 3d = 8 + 8
4d = 16
d = 16 /4
d = 4
Step-by-step explanation:
it's answer is c 23
Step-by-step explanation:
Here
The lines are parallel so
3x + 28° + 2x + 37° = 180°<being co-interior angles>
5x + 65° = 180°
5x = 180° - 65°
5x = 115°
Therefore x = 23°
After first week pond will be:
10 + 10* 0.03 = 10*(1.03) feet deep
after second week it will be:
10*(1.03) + 10*(1.03)*0.03 = 10*(1.03)^2
from this we can conclude that after x week its will be:
10*(1.03)^x
Note that when second week starts our starting pond is already greater by 3%. every week we add 3% of prevous weeks size of pond
for x = 8 we get
f(x) = 10*(1.03)^8 = 12.66 or rounded 13 feet
Answer is D.
X=2
2x-3=-x+3
add three to both sides
add 1x to each side
should be left with 3x=6
divide both sides by 3 to get x alone
your answer then is x=2
