Lin set up a lemonade stand. She sells the lemonade for $0.50 per cup.

Write an expression below to represent how much money Lin makes per cup, c.

Answers

Answer:

1 x 0.50

Step-by-step explanation:

This is true, because 1 x 0.50 is 0.50. That is the correct cost for one cup. 2 x .50 would be 1. That is the correct cost for 2 cups, and it would keep going on.

Answer:

1x $0.50

Step-by-step explanation:

The answer is $0.50.

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.

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.

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 :)

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)

so

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

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.
