In certain deep parts of oceans, the pressure of sea water, P in pounds per square foot, at a depth of d feet below the
surface, is given by the following equation
P=15+ 5d/11
If a scientific team uses special equipment to measures the pressure under water and finds it to be 435 pounds per square
foot, at what depth is the team making their measurements?

i dont know

step-by-step explanation:

-7/8

step-by-step explanation:

instead of subtracting you add the -6/8 and -1/8

1/3 + 1/3 ≠ 2/6 because 1/3 alone = 2/6  

step by step explanation:

1/3 + 1/3 = 2/3       2/3=4/6

yes

step-by-step explanation:

so of course you want to start by plugging the 5 in which goes to 7(5)+3(5)=50 because 7*5=35 and 3*5=15 and then add them together, then plug in the 5 to the other equation as well 9(5)+5=50 because 9*5= 45 and then add 5 and so yes they are equivalent.
