Answer:
The number of the cups of uncooked rice is 3 cups
The number of the cups of water is
cups
Step-by-step explanation:
* Let us read the recipe of Nasi Gorang
- 2 cups of uncooked rice need
cups of water to
make
cups of cooked rice
- Joseph needs
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 :
: 
⇒ x : y : 
- By using cross multiplication
∵ x (
) = 2 (
)
∵
= 
∵
= 
∴ x (
) = 2 (
)
∴
x = 13
- Divide both sides by 
∴ x = 3
∴ The number of the cups of uncooked rice is 3 cups
- By using cross multiplication
∵ y (
) = (
)(
)
∵
= 
∵
= 
∵
= 
∴
y = (
)(
)
∴
y =
- Divide both sides by 
∴ y = 
∴ The number of the cups of water is
cups
Given parameters:
Number of boxes Athena bought for the party = x
Number of cookies per box = 10
Number of cookies she brought to the party = 70
Number removed = 2 boxes
Unknown:
Equation of the number of boxes = ?
Solution:
1 box of cookies contains 10 cookies
If Athena, removed 2 boxes, in those two boxes, we have 20 cookies
Total number of cookies = 70 + 20 = 90 cookies;
So;
x = 
Therefore;
x =
boxes
Answer: length = 8 units
Width = 6 units
Step-by-step explanation:
Let L represent the length of the rectangular garden.
Let W represent the width of the rectangular garden.
The length of a rectangle is 2 units more than the width. This means that
L = W + 2
The area of the rectangle is 48 units. This means that
LW = 48- - - - - - - - - - - - -1
Substituting L = W + 2 into equation 1, it becomes
W(W + 2) = 48
W² + 2W = 48
W² + 2W - 48 = 0
W² + 8W - 6W - 48 = 0
W(W + 8) - 6(W + 8) = 0
W - 6 = 0 or W + 8 = 0
W = 6 or W = 8
Since the width of the rectangle cannot be negative, then W = 6
L = W + 2 = 6 + 2
L = 8
