Answer:
12 marbles per bag
Step-by-step explanation:
Your equation would be 3x=x+24 because you have 3 bags of marbles with x number of marbles per bag, and your friend has 1 bag with x marbles plus 2 additional marbles
Then you solve this equation
3x=x+24
Subtract x from both sides
2x=24
divide both sides by 2
x=12
The answer I get when plugging in 5 is 24
Answer:
68 degrees
Step-by-step explanation:
The ladder, the building and the ground together make up a right triangle with angle of elevation to be determined.
The side opposite this angle is 10 ft; the distance of the foot of the ladder from the building is 4 ft. Thus,
tan x = (opp side) / (adj side) = 10/4. Using the inverse tangent function, we find that the angle in question is
arctan (10/4) = 68 degrees
