Which shows how to solve the equation Three-fourths x = negative 6 for x in one step?

tino4ka555 [31]

Answer:

x = -8

Step-by-step explanation:

Let's put this into numbers: $\frac{3}{4}$ x =-6

The first thing you want to do is to multiply both sides by 4:

3x=-24

Next you need to divide by 3:

x=-8

The answer is -8

Answer:

Plan A equation: y = 10x + 30

Plan B equation: y = x + 80

Plan C equation: y = 5x + 50

Plan A costs the same as Plan C in 4 months

Plan A is the better option if you use 0 - 4 GBs of data each month

Plan B becomes the better deal when 8 months pass

Step-by-step explanation:

When does Plan A cost the same as Plan C?

Set the equations equal to each other (the cost) and solve for x (time in months)

10x + 30 = 5x + 50

5x = 20

x = 4 months

Which plan is best if you only use 0-4 GBs of data a month?

Test the maximum and minimum values to check which plan costs less

At 0 GBs of data used per month

Plan A: y = 0 + $ 30 = $30 total

Plan B: y = 0 +$80 = $80 total

Plan C: y = 0 + $50 = $50 total

At 4 GBs of data used per month

Plan A: y = $ 40 + $ 30 = $ 70

Plan B: y = $ 4 + $ 80 = $ 84

Plan C: y = $ 20 + $ 50 = $ 70

Comparing the plans at maximum and minimum amount of GBs used, only one plan has the lowest cost overall. Even though Plan C is the same price at 4 GBs as Plan A, when you use 0 GBs you will end up paying more in Plan C than Plan A. Therefore, Plan A is the better option

When does Plan B become the best deal?

When you plot the different Plans on a graph, the slope intercept of x = 7.5 (rounded up to 8) yields the lowest cost for plan B

Solve. 3(2w-7)=3 What is W?

almond37 [142]

- - Solve:

Start of by simplifying both sides of your problem.

3*2x+3*-7=32

6w+-21=3

6w-21=3

- - Now you need to add 21 to both sides to be able to finish solving.

6w-21+21=3+21

6w=34

- - Final step:

$\frac{6w}{6} = \frac{24}{6}$

Answer: w=4
