Sure, I can help you with these questions. Let's go through each one step by step:

1. To find the solution to 45 - (-60), you can think about it as subtracting a negative number, which is the same as adding the positive equivalent. So, 45 - (-60) becomes 45 + 60. Adding these two numbers gives you the solution: 105.

2. To order the integers from least to greatest, you can arrange them in ascending order. |-4| = 4, -10, 0, 5, 7. So the ordered integers from least to greatest are: -10, 0, 4, 5, 7.

3. Alan buys 3 dozen lightbulbs, which means he buys 3 x 12 = 36 lightbulbs. If he has 15 lightbulbs left, he used 36 - 15 = 21 lightbulbs.

4. To find the height of each floor rounded to the nearest whole number, you can divide the total height of the Empire State Building (1,250 feet) by the number of floors (103). So, 1,250 / 103 = 12.135. When rounded to the nearest whole number, the height of each floor is 12 feet.

5. To find the value of x in the equation 10x = -80, you can divide both sides of the equation by 10. So, 10x / 10 = -80 / 10. This simplifies to x = -8.

6. To solve the equation a/-5 = 7, you can multiply both sides of the equation by -5. So, (a/-5) * -5 = 7 * -5. This simplifies to a = -35.

7. To solve the equation -4 + h = 15, you can subtract -4 from both sides of the equation. So, (-4 + h) - (-4) = 15 - (-4). This simplifies to h = 19.

8. To write and solve an equation representing the situation where 35 people paid a total of $245 for admission to a local soccer game, you can let x represent the price of admission. So, the equation becomes 35x = 245. To solve for x, you divide both sides of the equation by 35. So, (35x) / 35 = 245 / 35. This simplifies to x = 7.

9. To simplify the expression 8*2 + 9 (12 / 3 x 2) - 7, you use the order of operations (PEMDAS). First, you calculate within parentheses and brackets. 12 / 3 = 4 and 4 x 2 = 8. So, the expression becomes 8*2 + 9 (8) - 7. Then, you perform multiplication and addition/subtraction from left to right. 8*2 = 16 and 9 (8) = 72. So, the expression simplifies to 16 + 72 - 7. Finally, you perform addition and subtraction. 16 + 72 = 88 and 88 - 7 = 81. Therefore, the simplified expression is 81.

I hope this helps! Let me know if you have any further questions.
