Determine the solution of the system. Show your work.<br> Y = 5x – 9<br> Y = 2x + 6

snow_tiger [21]

Both define y, so they are equivalent.

5x-9=2x+6
3x-9=6
3x=15
x=5

Then plug in x into any of the equations
y=2(5)+6
y=10+6
y=16

Final answer: (5,16)

Alice bought 18 toys, 48 books and 54 crayons to make boxes for a charity. She wants to use all of them in such a way that each

Strike441 [17]

Answer:

There would be 6 boxes, each with 3 toys, 8 books and 9 crayons.

Step-by-step explanation:

Find the greatest common factor of 18, 48 and 54 (the toys, books and crayons).

18 = 2*3*3

48 = 2*2*2*2*3

54 = 2*3*3*3

All of them have at least one 2 and one 3.

The greatest common factor is 6 because 2*3 is 6.

There will be 6 boxes.

The number of each item is the total items divided by number of boxes.

18/6 = 3

48/6 = 8

54/6 = 9

There would be 3 toys, 8 books and 9 crayons in each box.

At a rate of 36 miles per hour, it takes Henry 15 minutes to drive from the library to his house. Show how to find the distance

EastWind [94]

This is applying the formula
$distance=rate*time$

We have a slight problem, though, because we are measuring rate in miles per hour, and we are measuring time in minutes. To make this problem solvable, we need to convert to either miles per minute or convert the time to hours. I'm going to convert the 15 minutes into hours:
$15min*\frac{1 hour}{60 min}=\frac{1}{4}hour$

Now that all of the units match, we have:
$distance=36\frac{mi}{hr}*\frac{1}{4}hr$

You can finish from there I'm sure.

Which two statements contradict each other?

Rudik [331]

The answer is C. To contradict something is to say or do the opposite of what is stated. If point S lies on plane PQR, it cannot not lie on plane PQR.
