Answer:
3 + x
Step-by-step explanation:
Sum means to add, so you would just add 3 and x (since they haven't given an actual number and only a variable).
1. 8.32
2. 7.724
3. 54.889
4. 1.862068965517241
5. 100
6. 19.9832
7. 3.758
8. 13.9411
Answer:
Let's denote:
x: number of bicycles
y: number of skateboards
Then, we have:
x + y = 20
2x + 4y = 52
=> 2(20 - y) + 4y = 52
=> 2y = 12
=> y = 6 (number of skateboards)
=> x = 14(number of bicycles)
Hope this helps!

the slope of the line is y = -1/2x -2
