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.

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
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.
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.

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.
