Anna is in a cave 48 feet below the cave entrance. She descends 11 feet, then ascends 15 feet. Find her new position relative to the cave entrance.

74 feet.

Step-by-step explanation:

Add 11 and 15 together to get 26. Then, add 26 to 48 to get 74. So, Anna is now 74 feet below the cave entrance.

c.

step-by-step explanation:

because first you have to add the 4x, 9x, and the 7x together and you get 20x and then you add the last numbers up and you get 5and then you put the subtraction sign in there and that's how you get the answer.

5=812a+9+3

step 1: simplify both sides of the equation.

5=812a+9+3

5=(812a)+(9+3)(combine like terms)

5=812a+12

5=812a+12

step 2: flip the equation.

812a+12=5

step 3: subtract 12 from both sides.

812a+12−12=5−12

812a=−7

step 4: divide both sides by 812.

812a /812 = -7/812

a= -1/116

so the answer is

a=   -1/116
