Mount Ojos del salado is the highest mountain in Chile, with a peak at about 6900 meters above sea level. The Atacama Trench, just off the coast of Chile, is about 8100 meters below sea level (at its lowest point). what is the difference in elevations between mount ojos del salado and the atacama trench?

15,000 meters

Step-by-step explanation:

When measuring the difference in elevations between a body that is above sea level and one that is below, you simply take the distances of the bodies above and below sea level and add it up.

From sea level to Mount Ojos is 6,900 meters. Atacama trench is 8,100 meters below. From the peak of Mount Ojos to sea level is 6,900 meters. Then add the distance from sea level to Atacama to find the difference in elevations.

= 6,900 + 8,100

= 15,000 meters

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
