1/5x-8=4. what does x. equal​

Mathematics
1 answer:
Slav-nsk [51]3 years ago
8 0

Answer:

12

Step-by-step explanation:

if you multiply everything by 5, then you can get rid of the fraction and the equation would now look like this:

x - 40 = 20

and now you can answer this simply

x - 40 = 20

  +40   +40

x = 60

and since you multiplied 5 beforehand, now you have to divide by 5 to get the real answer

60 ÷ 5 = 12

therefore, x = 12

A consumer believes that a certain potato chip maker is putting fewer chips in their regular bags of chips than the advertised a
dybincka [34]

Answer:

a) No

b) No

c) P value is more than 0.05.  

Step-by-step explanation:

We are given the following in the question:

Population mean, μ = 12 ounces

Sample size, n = 49

P-value = 0.136

First, we design the null and the alternate hypothesis

H_{0}: \mu = 12\text{ ounces}\\H_A: \mu < 12\text{ ounces}

We use One-tailed z test to perform this hypothesis.

a) Alpha, α = 0.05

Since, p-value > α,

The null hypothesis should not be rejected. We accept the null hypothesis and reject the alternate hypothesis. We conclude that the average chip weight is 12 ounces per bag.

b) Alpha, α = 0.10

Since, p-value > α,

The null hypothesis should not be rejected. We accept the null hypothesis and reject the alternate hypothesis. We conclude that the average chip weight is 12 ounces per bag.

c) The evidence is statistically significant at the .05 level means that the p value is more than 0.05.

The distance, y, in miles, traveled by a car for a certain amount of time, x, in hours, is shown in the graph below:
Kazeer [188]
Answer: The correct answer is the last choice.

In the first segment of the trip, the car goes from 0 to 2 hours and the line is moving up. Therefore, it traveled for 2 hours.

In the second segment, the line went straight horizontal for 1 hour. That means the distance didn't change, in other words it didn't move.

In the last segment, it moved up again for 2 hours.

A store owner puts in an order for product x and product y for a total of 4,000 units. it costs $0.10 per item to ship of produc
galben [10]

The system of equations can be used to determine how much of product x and product y the store owner bought is x + y = 4,000

0.10x + 0.04y = 352

<h3>Simultaneous equation</h3>

  • product x
  • Product y
  • Total units of x and y = 4,000 units
  • Cost of shipping each product x = $0.10
  • Cost of shipping each product y = $0.04
  • Total cost of shipping = $352

The equation:

x + y = 4,000

0.10x + 0.04y = 352

Therefore, the system of equations can be used to determine how much of product x and product y the store owner bought is x + y = 4,000

0.10x + 0.04y = 352
