Answer:

3^2 +9

Step-by-step explanation:

Since 2+4^2 is 16+2 which is 18, you need to find the expression equivalent to 18. 25 doesn't work so eliminate that right away. 9^2=81 so that isn't right either. 2^3+9=17 so that is incorrect. Lastly, 3^2+9=18 so that is the correct answer.

Answer:

(3^2)+9

Step-by-step explanation:

Since 2+(4^2)=18 all you have to do is find an equation that equals 18, and the equation available is (3^2)+9=18, it makes both equations equal to each other and they both equal 18

Before an election: 23% said they would vote for A, 9% said they would vote for B, 20% said they would not vote. these all voted
elena55 [62]
It would be B because if the total population was 100 people then 23 would vote for A, and 9 would vote for B. Then, 20 people would not vote. The total number of people now is 52, so there are 48 more people left to vote and at a 1:2 ratio it would be 16:32. If you add 16 to the original 23 for A, that would equal 39 total votes for A. If you add the 32 to the original 9 for B, that would equal 41 for B. And then 20 are left over for the non-voters. Therefore, B has the most votes.

Irina rode her bike to work at an average speed of 16 miles per hour. It started to rain , so she got a ride home along the same
Lyrx [107]
Here, the distance traveled is not given, but Irina's bike-riding speed is:  it is 16 mph.

Let the distance traveled be d.  Then d = (27 mph)(0.4 hr) = 10.8 miles.

By bicycle, distance = rate times time.  Here, 10.8 miles = (16 mph)(time), and so

                10.8 mi
time = --------------- = 0.675 hour (40.5 minutes).
             16 mph

Michael pays his cell phone service provider $49.95 per month for 500 minutes. Any additional minutes used cost $0.15 each. In J
arsen [322]

y = total cost used.

x = additional minutes

y = $49.95 + $0.15x

$61.20 = $49.95 + $0.15x. Subtract the $49.95 from each side.

$11.25 = $0.15x. Divide each side by $0.15

75 = x.

Michael used 75 additional minutes.
