Aleks04 [339]2 years ago
4 0

Answer:

one, no, one, infinitely

Step-by-step explanation:

a. you can get 7x = 21 - 21 = 0 ==> x = 0

b. subtract 12x from both sides ==> get 15 = -15, which is not true

c. -5x-5x=25+25 ==> -10x = 50 ==> x = -5

d. get -2x -6 -7 = -2x - 6 - 7 ==> so it's infinitely

Joseph needs 6 1/2 cups of cooked rice for a recipe of nasi gorang. If 2 cups of uncooked rice with 2 1/2 cups of water make 4 1
liraira [26]

Answer:

The number of the cups of uncooked rice is 3 cups

The number of the cups of water is 3\frac{3}{4} cups

Step-by-step explanation:

* Let us read the recipe of Nasi Gorang

- 2 cups of uncooked rice need 2\frac{1}{2} cups of water to

  make 4\frac{1}{3} cups of cooked rice

- Joseph needs 6\frac{1}{2} cups of cooked rice

- We need to know how many cups of uncooked rice Joshep needs

  for this recipe and how much water should be added

* We can solve this problem by using the ratio method

⇒ uncooked cups   :   water cups   :   cooked cups

⇒ 2                           :   2\frac{1}{2}                   :  4\frac{1}{3}

⇒  x                           :   y                     :  6\frac{1}{2}

- By using cross multiplication

∵ x ( 4\frac{1}{3} ) = 2 ( 6\frac{1}{2} )

∵ 4\frac{1}{3} = \frac{13}{3}

∵ 6\frac{1}{2} = \frac{13}{2}

∴ x ( \frac{13}{3} ) = 2 ( \frac{13}{2} )

∴ \frac{13}{3} x = 13

- Divide both sides by \frac{13}{3}

∴ x = 3

∴ The number of the cups of uncooked rice is 3 cups

- By using cross multiplication

∵ y ( 4\frac{1}{3} ) =  ( 2\frac{1}{2} )( 6\frac{1}{2} )

∵ 2\frac{1}{2} = \frac{5}{2}

∵ 6\frac{1}{2} = \frac{13}{2}

∵ 4\frac{1}{3} = \frac{13}{3}

∴ \frac{13}{3} y = ( \frac{5}{2} )( \frac{13}{2} )

∴ \frac{13}{3} y = \frac{65}{4}

- Divide both sides by \frac{13}{3}

∴ y = 3\frac{3}{4}

∴ The number of the cups of water is 3\frac{3}{4} cups
