(neither edges nor corners).
such as the whole grid can be upside down (64 on top and 53 on bottom)
or it can be reversed left to right.
When are we ever gonna use Math? On placement tests!
First click on this to see what students need to know:

The link above should be required reading (& writing & arithmetic) for all middle and high school students, their teachers, principals and families.
If high schools can share this information and help students ace their placement tests, then students can ace their placement tests, avoid remedial classes and take actual college courses.
Up to 75% of students end up in remediation and more than half the courses offered are at the remedial level.

Make sure you know what’s on the placement test and not just Math — Reading and Writing too! This is especially important for community college students as placement tests are administered to all students and 75% are placed into remedial classes aka developmental mathmatics..
CUNY (City University of New York) just switched to the ACCUPLACER placement tests from COMPASS which is being discontinued. Here is a link to an app for practice on this content:

Notice how much it is for each additional hour:
$5.50. (9.00 – 3.50, 14.50 – 9.00, 20.00 – 14.50)
Let’s substitute in 5.50 into each equation and see if it makes the equation true.
(1) 9.00 + 3(5.50) = 20.00 that one is NOT true because 9 + 16.50 = 25.50 does NOT = 20
(2) 9.00 + 3.50(5.50) = 20 also not true
(3) 2 (5.50) + 9 = 11 + 9 = 20 🙂
(4) 2 (5.50) + 9 does not equal 14.50.
That’s it — 2 more points!
(albeit very cheap parking rates)
Putting both equations into Y= and studying the table can help us solve this one!!
Now we must read carefully! What is the largest integer for which f(x)>g(x)?
For x = 7, f(x) = 13484 and is greater than g(x) = 2187
For x = 8, f(x) = 22409 and is still greater than g(x) = 6561
For x = 9, f(x) = 35244 and is still greater than g(x) = 19683
For x = 10, f(x) = 53009 and is NO LONGER greater than g(x) = 59049
983 + 86 + 8 = 1077
writing it vertically helps a lot
The B has to be a 1 as the total would be over 1000 and the M has to be a 9 as we are only adding a two digit and 1 digit number and getting over 1000
the last column must be adding up to 17 rather than 7 (otherwise S + A would be 4 and would be 1 and 3 but 3 is already used)
so S + A = 14 and since there will be a carry the next column over A + A + 1 will equal 17
so A = 8 and therefore A = 6
So which one is NOT true??
(1) At o seconds, height was 180 so this is ok
(2) The highest height was 324 ft which happened at 3 seconds
(3) Um, at 7 seconds, it is still 68 feet above the ground
(4) From 2 to 4 seconds, the height is in the 300s
