To solve this problem, we need to determine the value of x, which represents the number of social studies problems Brooke has for homework.
Let's break down the information given:
Number of math problems: 15
Number of science problems: 10
Time taken to answer each math problem: 2 minutes
Time taken to answer each social studies problem: 30 seconds = 0.5 minutes
Time taken to answer each science problem: 1.5 minutes
Total time taken to answer all homework: 48 minutes
We can set up the equation as follows:
(Number of math problems * Time taken for each math problem) + (Number of social studies problems * Time taken for each social studies problem) + (Number of science problems * Time taken for each science problem) = Total time taken
(15 * 2) + (x * 0.5) + (10 * 1.5) = 48
Let's simplify and solve for x:
30 + 0.5x + 15 = 48
0.5x + 45 = 48
To isolate x, we subtract 45 from both sides of the equation:
0.5x + 45 - 45 = 48 - 45
0.5x = 3
To solve for x, we divide both sides of the equation by 0.5:
x = 3 / 0.5
x = 6
The value of x is 6.
#### 6
The answer is: 6
Below is a math problem. Provide a detailed, step-by-step solution.

### Problem:
For homework, Brooke has 15 math problems, x social studies problems, and 10 science problems. He can answer each math problem for 2 minutes while answering each social studies problem takes him 30 seconds. If he can answer each science problem in 1.5 minutes, It will take Brooke 48 to answer all his homework.

### Answer:
