Read through this series of events that lead to cellular respiration, or the production of energy in your body. Put these events in the correct order by numbering them from 1 to 5 in the blank boxes next to the events. ¼
You eat a hamburger and breathe in oxygen.
Oxygen and glucose combine to form carbon dioxide, water, and ATP.

Energy is used by cells in your body to function and grow; you exhale carbon dioxide.

Oxygen goes immediately from your lungs to blood vessels to cells.

Food molecules in the hamburger are broken down into glucose in the digestive system.

answer: y = -2.5x - 15

step-by-step explanation:

agree

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
