The Reeds are moving across the country. Mr. Reed leaves 4.5 hours before Mrs. Reed. If he averages 70 mph and she averages 85 m

Bond [772]

I was originally going to graph the two equations, but I don't have graph paper so I set the equations equal to each other.
so Mr.Reeds equation is: y=70x+4.5 and Mrs.Reeds equation is: y=85x
so if I set these equal to each other I would minus the 70x from both sides leaving me with 15x = 4.5. Now since that's done I would divide everything by 15 which will cause me to get a fraction. So once that's done I would be left with x=3/10. I hope this helped!

96 = 3(6x + 2) Ik confused

Aleonysh [2.5K]

Answer:

x=5

Step-by-step explanation:

96= 3(6x+2)

distribute 3 by multiplying everything inside the parenthesis by 3

96= 18x + 6

subtract 6 from each side

90=18x

divide each side by 18

I keep putting in the formula but I keep getting the answer wrong

Answer:

314 in² (nearest whole number)

Step-by-step explanation:

Radius of a regular polygon: The distance from the center of the polygon to any vertex. The radius of a hexagon is equal to the length of one side.

Therefore, from inspection of the given diagram:

radius = 11 in ⇒ side length = 11 in

To find the area of a regular polygon, we first need to calculate the apothem. The apothem is the line drawn from the center of the polygon to the midpoint of one of its sides.

$\textsf{Length of apothem (a)}=\dfrac{s}{2 \tan\left(\frac{180^{\circ}}{n}\right)}$
