Solve 5x + 3x - 6 = 42​
xxMikexx [17]

Answer:

The answer to your question is x = 6

Step-by-step explanation:

Equation                   5x + 3x - 6 = 42

Process

Step 1. Add 6 units in both sides

                                 5x + 3x - 6 + 6 = 42 + 6

Step 2. Simplify

                                  5x + 3x = 48

Step 3. Simplify like terms

                                         8x = 48

Step 4. Divide by 8 both sides

                                        8x/8 = 48/8

Step 5. Simplify

                                          x = 6

HELP PLZ ...........WITH ALL OF THEM
Setler79 [48]

Answer:

1/2

Step-by-step explanation:

We first find the least common multiple, which is 6. Therefore, we can multiply 1/3 x 2/2 (since 2/2 is equal to one and won't change the final amount) and get 2/6. 2/6+1/6=3/6, or 1/2.

So B) has all the requirements

The vertical line in the box represents the mean which if you add all the numbers and divide by 15 you get 17 and since no other whisker box plot doesn't have 17 as its mean B is the only logical answer
