Trista solved an equation for x. Her solution is shown below.

36 + x = 54

36 + x - 36 = 54 + 36

x = 90

Is Trista's solution correct? If not, what error did she make and what is the correct answer. Explain. plzzzzzzzzzzzzzzzzz

Answers

It’s incorrect bc you’re using inverse operations to solve the equation so she wasn’t supposed to add 36 to 54 what she was supposed to do was subtract 36 from 54 and well that would be your answer “x=28”

Answer:

x is 54-36=18

x= 18

I really need help guys! Please answer with detail, will give brainliest. What is velocity?

Answers

A velocity is when it determines an accuracy on the acceleration of it’s rate in transitions from it’s movement.

Answer:

Velocity is defined as the rate of travel of an object, along with its direction. Velocity tells you how fast an object is moving as well as in what direction it is moving. It is similar to speed, except that it also adds direction. So, while speed is directionless, velocity is directional speed.

Kareem cannot decide which of two washing machines to buy. The selling price of each is 650$. The first is marked down by 40%. The second is marked down by 10% with an additional 30% off. Find the sale price of each washing machine. Use pencil and paper. Explain why should buy the first washing machine rather than the second if the machines are the same except for the selling price.

Answers

Answer: this is long divide
Step-by-step explanation: first 585 - 50% = ?
Then do that first total and add or subtact 50 % then add I think or it might be the other way for your real total. it should not change the price for the first machine and that is why would want it. Sorry it's been a while since I have done math use a caluator if you have to

Answer:

The first one cost $390, while the second one cost $409.50

Step-by-step explanation:

650 x .10 =65

650-65=585

585 x .30 = 175.5

585-175.5=409.5

650 x .4 =260

260<409.5

Since the second washing machine is being marked off by 10% first then by 30% percent second, the 30% would be taking away less of the total price than if you did all 40% at one time. I hope this helps

Johnathan’s drive from his house to school is at least 45 miles or more. Write an inequality that displays his possible driving distance.

Answers

Answer:

1) ≤ 200 (less than or equal to 200 lb because Imani cannot have more than 200)

2) ≥ 45 (greater than or equal to 45 miles because Johnathan's drive is 45 miles or more)

A man needed to sell a car. He priced it at $3,500 the first day. The second day he reduced the price by 15%. What was the price of the car after this reduction?

Answers

Answer:

2975

Step-by-step explanation:

15 percent of 3500 is 525, so 3500-525 is 2975

Answer:

$2975

Step-by-step explanation:

He is reducing the price. So we are going to multiply it by the percentage to see how much the car was reduced, then subtract it from the actual equation.

But first, let's convert 15% into a decimal. 15% as a decimal is just 0.15. Let's write out the equation.

3500 x 0.15 = 525

The car was reduced by $525.

Now let's subtract it from the original price of the car.

3500 - 525 = 2975

Therefore, the mans' car was priced at $2975 on the second day, after being reduced by 15%, which is also known as 0.16.

A picnic table was marked up 165% from an original cost of $200. Last Friday, Suzie bought the picnic table and paid an additional 10% in sales tax. What was her total cost?

Answers

363

200•1.65=330
330•1.1=363

So they answer would be 363

Answer:

The total cost is $583

Step-by-step explanation:

if it was marked up 100%, it would be $400, so we need to find out what 65% of 200 is and add it to 400. 65% of 200 is double 65% of 100, so 65*2=130. 400+130= $530 as the new price. this sales tax would be 10% of the NEW price, so we need to find 10% of 530. 530 divided by 10 is 53, now we need to add it to the new price. 530 + 53 = $583.
