The pressure, P, measured in pounds per square inch (psi), on an object under water varies directly with its depth, d, measured in feet. If the pressure on an object at a depth of 20 feet is 8.6 psi, what is the pressure on an object at a depth of 25 feet?
A. 9.85 psi
B. 10.75 psi
C. 13.60 psi
D. 6.88 psi

10.75 psi i'm pretty sure

Step-by-step explanation:

i'm not sure if this will make sense though

p=kd <-direct variation

8.6 = k × 20               p= .43d

k= .43                         p= .43 (25)

                                           =10.75psi

understand that i don't know the answers

will someone answer his question

x ≥ 18 is your answer

step-by-step explanation:

let "a number" = x

(2/3)x + 17 ≥ 29

isolate the variable (x). do the opposite of pemdas (parenthesis, exponent (& root), multiplication, division, addition, subtraction).

first, subtract 17 from both sides.

(2/3)x + 17 (-17) ≥ 29 (-17)

(2/3)x ≥ 29 - 17

(2/3)x ≥ 12

next, multiply 3/2 to both sides to isolate the x

(3/2)(2/3)x ≥ 12(3/2)

x ≥ 12(3/2)

simplify. multiply, then divide

x ≥ (12 * 3)/2

x ≥ (36)/2

x ≥ 18

x ≥ 18 is your answer
