Let's say the first day he studied for x minutes.
Each day he studies 5 more minutes than his previous day.
Day 2: x +5
Day 3: x + 10
Day 4: x + 15
Day 5: x + 20
And finally the last day: x + 25
To find the difference all u need to do is take the amount he studied on the first day and subtract it by how much he studied the last day.
X - X + 25
Which gives u a difference of 25

Hello :
answer : <span>B (5x - 3)(2x - 1)
because : </span>(5x - 3)(2x - 1) = 10x²-5x-6x+3 = 10x²-11x+3
Distance=speed times time
distance/time=speed
distance=30km
time=2.5hr
distance/time=30km/2.5hr=60km/5hr=12km/1hr=12km/hr
her speed is 12km per hour
Answer:
48 degrees
Step-by-step explanation:
A triangle has three angles that add up to 180 degrees. In a right triangle, one of the angles in 90 degress, and the other 2 add up to 90. In this case, we have 2 given angles, 90 degree angle and 42 degree angle. If we do 90+42 it gives us 132. We then subtract that from 180 to give us 48 degrees.
