Answer:
(b*amount of money per hour) + (s*amount of money per hour).
Step-by-step explanation:
Answer:
m < 36
yes, Jamie is correct.
Step-by-step explanation:
I've bolded the statements that you can put down to show your work
the maximum that Jamie is willing to practice for the week is 300 minutes, so you can start by creating an inequality for that.
total minutes throughout the week < 300
next, you know that a week is monday through friday + the weekend, and the amount of minutes Jamie will practice for the weekend is already given.
so, you can rewrite the earlier inequality like so
Monday through Friday practice + 120 < 300
since Jamie plans to practice the same amount of time (m) for each day, and there are 5 days between monday and friday, you can substitute values in the equation
5m + 120 < 300
simplify
5m < 300 - 120
5m < 180
m < 36
since half an hour is 30 minutes, the answer is yes, Jamie's claim is correct.
[[x]] means to round down to the greatest integer less than or equal to x.
1. (x - 9) + (x + 5)
You split the x^2 into two xs
The one with an x (-4x) is what the two numbers should equal
-9 + 5 = 4
The one without an x (-45) is what the two numbers product should be
-9 times 5 = -45
*so remember the x is the sum of the two
*no x is the product of the two
Theres no quick trick to find the answer u just have to plug it in
*start with all the numbers that multiply for the no x (-45)
-3 and 15 or 3 and -15 is obviously not it as the sum does not equal -4
Those sums equal 12 or -12
I’ll do one more and ur on ur own comrade (ok and ill do number 4)
3. (x - 8) + (x - 9)
ok this time both the answers have a negative
*if it has only one negative in the problem there are going to be TWO negatives in the answer
-8 and -9 sum is -17
-8 and -9 sum is 72
If there was only one negative in the answer it would make the 72 negative and there is no -72 in the problem
So this one is
(x - 8) + (x - 9) (u dont have to have it like this u can put the (x - 9) in the front doesn’t matter which way it’s just the signs (- & +) that matter
OK now 4.
4. This one is very easy as all u need to do is find the two numbers for the product
(X - 6) (X + 6)
(Again it doesn’t matter which () is in front just the SIGNS INSIDE THE PARENTHESES ( + & - )
