Acement bridge post is 24 inches square and 15 feet 9 inches in length. if the cement weighs 145 pounds per cubic foot, how much does one bridge post weigh? a. 9,280 pounds b. 9,222 pounds c. 9,135 pounds d. 8,700 pounds

it is not that hard all u have to do is plot the graph

step-by-step explanation:

you just switch the numbers basically so it would be 3/17

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
