Jim needs to rent a car. A rental company charges $21 per day to rent a car plus $0.80 per mile driven. How many miles can he drive in a day if he wants to spent AT MOST $82. Write an inequality. Show work Or explain how to solve it and then give a solution as an inequality.

Answers

Answer:

Inequality: .80x +21 ≤ 82

Answer: 76.25 miles in total

Step-by-step explanation:

Hi,

An inequality to represent this is .80x +21 ≤ 82

(.80 is the cost per mile and x is the number of miles driven. 21 is the fee that must be paid no matter what and the 82 is the total cost they can pay. We use the ≤ sign to say they can spend less than or equal to 82. The phrase "at most" means we can use the ≤ sign).

Now we solve...

.80x + 21 ≤ 82

Subtract 21 on both sides...

.80x ≤ 61

Now, divide by .80 on both sides...

x ≤ 76.25

He can drive up to 76.25 miles in total

Hope this helps :)

Erik transformed the equation y = 2(x − 2)^2 + 5 from vertex form to standard form. His steps are shown below. Is Erik's work correct? If not, identify and correct his error.
y = 2(x − 2)^2 + 5
y = 2(x^2 − 4x + 4) + 5
y = 2x^2 − 8x + 8 + 5
y = 2x^2 − 8x + 13
A. No. The error is in the second line: the expanded form of (x − 2)^2 is x^2 − 4.
B. No. The error is in the third line: the product of 2 and x^2 − 4x + 4 is 2x^2 − 4x + 4.
C. No. The error is in the fourth line: the sum of 8 and 5 is 12.
D. Yes. Erik is correct in his transformation from vertex form to standard form.

Before outlier : 7.25
After outlier : 4

7.25 - 4 = 3.25

So the mean decreases by 3.25 when the outlier is removed.

The length of a rectangle is 3 times its width. If the length were increased by 2 inches and the width by 1 inch, the new perimeter would be 62 inches. What is the width and length of the rectangle? If w represents the width of the rectangle, then which equation could be used to solve for w?
2(4 w + 3) = 62
( w + 1)(3w + 2)=62
2(3 w + 3) = 62

Answers

pretty sure it’s the second option because length would be 3w+2
and width would be w+1 and with area you have to multiply so it would just be the (w+1)(3w+2)

Answer:

2(4 w + 3) = 62

width =7 length = 21

Step-by-step explanation:

For the perimeter you need :

2 times the width and 2 times the length (length =3w)

2(w+1) + 2 (3w+2) =

2w+2 + 6w+4 =

8w +6

you can factor this by:

2(4w+3)

8w +6= 62

8W = 56

w= 7 l= 21

2(7+1) + 2 (21+2)

16 + 46 = 62

4/9 kilogram of baking soda costs $2. How much does 1 kilogram of baking soda cost?

please drop an explanation, and equation thanks!

Answers

Ok so we want to cross multiply.
To do this you know 4/9=2$ so now you want to know 1=x$
When you do this you get $5

Answer:

1 kg of baking soda costs $4.50.

Step-by-step explanation:

Write and solve an equation of ratios, as follows:

4/9 kg $2

------------- = --------------

1 kg x

Multiplying both numerators by 9, we get:

4 kg $18

------------ = ---------

1 kg x

Cross-multiplying, we get 4x kg = $18-kg. Solving for x, we get:

$18-kg

x = -------------- = $4.50

4kg

1 kg of baking soda costs $4.50.

What property of equality would you use to solve the equation n/4 = 16.

Answers

Answer:

Multiplication Property of Equality.

Step-by-step explanation:

Isolate the variable, n. Note the equal sign, what you do to one side, you do to the other.

Multiply 4 to both sides of the equation:

(n/4) * 4 = (16) * 4

n = 16 * 4

n = 64

n = 64 will be your answer.

The equation n/4 =16,the answer is 64.

Read the passage from Ronald Reagan's "Tear Down This Wall" speech.In the 1950s, Khrushchev predicted: "We will bury you." But in the West today, we see a free world that has achieved a level of prosperity and well-being unprecedented in all human history. In the Communist world, we see failure, technological backwardness, declining standards of health, even want of the most basic kindtoo little food. Even today, the Soviet Union still cannot feed itself. After these four decades, then, there stands before the entire world one great and inescapable conclusion: Freedom leads to prosperity. Freedom replaces the ancient hatreds among the nations with comity and peace. Freedom is the victor.And now the Soviets themselves may, in a limited way, be coming to understand the importance of freedom. We hear much from Moscow about a new policy of reform and openness. Some political prisoners have been released. Certain foreign news broadcasts are no longer being jammed. Some economic enterprises have been permitted to operate with greater freedom from state control. Are these the beginnings of profound changes in the Soviet state? Or are they token gestures, intended to raise false hopes in the West . . . ?
