Hi I need help with 4 problems you don't have to answer all of them just the ones you think you might know and I need to know how to do it. The questions are below:) 1. -3x + 10
2. 4x +8
3. -1 - 4x
4. 7 -5x

1.    -30x     2. 12x    3.   x         4.  2x

Step-by-step explanation:

i believe the way your learning is that you have to add or subtract both numbers and then add the letter next to the answer.  number 3 is just x because -1- 4x = 0 and just add the x.

3-4

step-by-step explanation:

the answer is 3-4 because both 45 and 60 has a multiple of 15.

45/3=15

60/4=15

therefore the odds against selecting a red is 4-3
