Answer:
3i √3
Step-by-step explanation:
you can't have the square root of a negative number
so we use "i"
The 81 balls need to be split into some number of boxes. To figure out how many boxes, we can divide the 81 balls by the 7 ball capacity of a single box.
81/7 = 11.571
This means that we will need 11 full boxes, but there will be a remainder of balls which did not fit. Since we can't have a fraction of a box, we need to round up to 12 boxes to hold all 81 balls.
The answer is 12 boxes.
D. since 11% in decimal is 0.11 only. 1/9 in decimal is 0.111111111... 0.12 jorge and 1/8 in decimal is 0.125
Answer:
6. A; 7. D
Step-by-step explanation:
6. 2=5j-28 - Add 28 to both sides
30=5j- Divide by 5 to both sides.
6=j
7. 3/5n +3=18- Subtract by 3 on both sides.
3/5n=15- Multiply by the reciprocal of 3/5 to both sides.
n=25

The first two letters are brackets and indices, which you didn't include, so past that is
1. Division
2. Multiplication
3. Addition
4. Subtraction
I don't know how to form that into a 'mathematical sentence' though
