<h3>(2-1) + 3² ÷ 3.</h3>
<em>To divide powers with the same base, subtract the exponent in the denominator from the exponent in the numerator. Subtract 1 from 2 to get 1.</em>
<h3>2 − 1 + 3¹</h3>
<em>Subtract 1 from 2 to get 1.</em>
<h3>1 + 3¹</h3>
<em>Calculates 3 to the power of 1 and gets 3.</em>
<h3>1 + 3</h3>
<em>Add 1 and 3 to get 4.</em>
<h3>4</h3>
The correct option is Alternative "C".
If the track is 10km long, and X travels at 40 km/h, it will take 1 hour to do 4 laps. this means that car X will do one lap in 15 minutes. Y travels at 30 km/h, which means it will do 3 laps in 1 hour, meaning that car X will do 1 lap in 20 minutes.
X- 15, 30, 45, 60
Y-20, 40, 60
Therefore, after an hour, they will pass again.
1. -37b-1
2. X=24
3. Z=18.
Hope this helps!
Step-by-step explanation:
Let the two numbers be x and y.
From equations (1) & (2)
Thus, the two numbers are (4, - 2) or (-2, 4).
The answer would be 7+5/6b
