Answer:
<h2>y=7x-47</h2>Step-by-step explanation:
If BE = 2x + 2, BD = 5x – 3, and AE = 4x – 6, what are the values of x and AC?
1 answer:
Answer: x=7 and AC = 44 unuts.
Step-by-step explanation:
We know that the diagonals of a parallelogram bisect each other. (i)
Here in parallelogram ABCD , AC and Bd are diagonals intersecting at E.
BE = 2x + 2, BD = 5x – 3, and AE = 4x – 6
Using (i)
Now , AE = 4(7)-6 = 28-6 = 22
AC =2 AE = 2 (22) =44 units.
Hence, x=7 and AC = 44 unuts.

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
