10. A small plane was scheduled to fly from Atlanta to Washington, D.C. The plane flies at a constant speed of 230 miles per
MatroZZZ [7]

Answer:  The plane had traveled about 264 miles before turning back. The average speed was 230 mph

Step-by-step explanation: 230 - 10 = 220 speed outgoing

230+10 = 240 speed returning  

Average speed (220+240)÷2= 460/2 =230 mph (needless to calculate!) Multiplied by total time 2.3 hours = 529 miles total distance.

Traveling the entire distance at 220mph would take about 2.4 hours. Traveling the entire distance at 240mph would take about 2.2 hours, a difference of .20 hours. Cut those times in half:

Traveling at 220mph for 1.2 hours would cover about 264 miles.

Traveling at 240mph for 1.1 hours would cover about 264 miles.

It adds up to 528 miles. The plane can't turn instantly, so figure the turn took the missing mile!

4-(2y-1)=2(5y+9)+y please help quick
stich3 [128]

Step-by-step explanation:Step 1: Simplify both sides of the equation.

4−(2y−1)=2(5y+9)+y

4+−1(2y−1)=2(5y+9)+y(Distribute the Negative Sign)

4+−1(2y)+(−1)(−1)=2(5y+9)+y

4+−2y+1=2(5y+9)+y

4+−2y+1=(2)(5y)+(2)(9)+y(Distribute)

4+−2y+1=10y+18+y

(−2y)+(4+1)=(10y+y)+(18)(Combine Like Terms)

−2y+5=11y+18

−2y+5=11y+18

Step 2: Subtract 11y from both sides.

−2y+5−11y=11y+18−11y

−13y+5=18

Step 3: Subtract 5 from both sides.

−13y+5−5=18−5

−13y=13

Step 4: Divide both sides by -13.

−13y

−13

=

13

−13

y=−1

 Answer: y =-1
