Math i will give yo brainlest i did this two time and this is the last if i don't get a good grade i will fail .a. investigate the weather forecast in your city. record the high and low temperatures that are forecast for the next 7 days in the table below. in the columns titled, difference," record the change in temperature from the day before. to do this, subtract the previous temperature from the current temperature. be sure to use positive and negative numbers as needed! for example, if yesterday’s temperature was 70 and today’s temperature was 65, the difference is 65 – 70 = -5. here's an example: note: the columns for day one's subtraction and difference cannot be filled in. as this is the first data point, there is no previous temperature to subtract.

i hope i

you divide them and then you get the answer i took this class this year

step-by-step explanation:

third choice down

step-by-step explanation:

the first inequality is based on the number of adults and campers, and the second inequality is based on the cost of feeding both the adult and the camper.

we know that there is room for 525 people max.   it's ok to have less than 525, but it's not ok to have more than 525, so the inequality is less than or equal to.   the number combination of adults (x) and campers (y) cannot exceed this 525 max.   therefore:

x + y ≤ 525

now we talk about cost.   it costs $9 to feed one adult, so depending upon the number of adults you have (x) depends upon how much it will cost to feed that number of adults.   same with the campers, who cost $5 to feed.   the adults can be represented by 9x and the campers can be represented by 5y.   since the budget cannot exceed 1,200, the second inequality is:

9x + 5y ≤ 1200
