We have been given that

Luke can read 4 3/4 pages in 15 minutes.

Hence in 1 minute Luke can read 19/60 pages.

Sarah can read 1 1/2 pages in 4 minutes.

Hence, in 1 minute Sarah can read 3/8 pages.

Now, let us find how many pages they can read in 2 hours = 120 minutes.

In 2 hours Luke can read \frac{19}{60} \cdot 120 = 38 pages.

In 2 hours Sarah can read \frac{3}{8} \cdot  120 = 45 pages.

The difference in the number of pages is 45 - 38 = 7 pages.

Therefore, Sarah can read 7 more pages than Luke in 2 hours.

Find the X COORDINATE OF THE intersection of 9x - 6y = 12 and 3x + 2y =8
yaroslaw [1]

Answer: x=2

Step-by-step explanation:

Given a System of linear equations, the solution of the system is the point (x,y) in which the lines intersect, where "x" is the x-coordinate and "y" is the y-coordinate.

Having the following System of equations:

\left \{ {{9x - 6y = 12} \atop {3x + 2y =8}} \right.

You can use the Elimination method to find the value of "x":

-Multiply the second equation by 3.

- Add the equations.

- Solve for "x".

Then, you get:

\left \{ {{9x - 6y = 12} \atop {9x +6y =24}} \right.\\.......................\\18x=36\\\\x=\frac{36}{18}\\\\x=2

PLEASE HELO ME AND EXPLAIN PLEASE. AND PLEASE SHOW IN STEPS!! i will mark brainliest if you get it correct!
Dimas [21]

Step-by-step explanation:

The height of the swipe card is given by :

h(t)=-3t^2+15t+18 .....(1)

We need to find the maximum height of the swipe card and the time to reach the maximum height.

For maximum height, put dh/dt = 0

So,

\dfrac{d}{dt}(-3t^2+15t+18)=0\\\\-9t+15=0\\\\t=\dfrac{15}{9}\\\\t=1.67\ s

It will take 1.67 seconds to reach the maximum height.

Now, put t = 1.67 s in equation (1).

h(1.67)=-3(1.67)^2+15(1.67)+18\\\\=34.68\ feet

Hence, the maximum height of the swipe card is 34.68 feet and the time to reach this height is 1.67 s.
