4/9 kilogram of baking soda costs $2. How much does 1 kilogram of baking soda cost?
please drop an explanation, and equation thanks!
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.
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
