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.

Answers

|16.5|
EXPLANATION.
the farthest away number on the number line is the greatest number. (don’t worry about - its the same distance on left and right of the number line)
So if we look at the numbers it is clear that 16.5 is the greatest number. meaning it is the farthest from 0.

The answer is 16.5 because if you look at the number line it is farthest away

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.

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

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.
