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.

answer: all the values are within because it has a pattern that repeats from -6 to 4.

good luck!

total amount to be paid = $19.5

step-by-step explanation:

given ,

original price = $25.99

discount = 25%

discount amount = 25% of original price

discount amount = 25/100   * 25.99

discount amount = $6.49

hence , the total amount to be paid = original price - discount amount

                                                            = $25.99 - $6.49

                                                            =$19.5

total amount to be paid = $19.5
