Answer: the bill for a glass of apple juice is $0.7 and the bill for a salad is $1.5
Step-by-step explanation:
Let x represent the bill for a glass of apple juice.
Let y represent the bill for a salad.
The bill for five glasses of apple juice and four salads is $9.50. It means that
5x + 4y = 9.5 - - - - - - - - - - - 1
The bill for four glasses of apple juice and five salads is $10.30. This means that
4x + 5y = 10.30- - - - - - - - - - - -2
Multiplying equation 1 by 4 and equation 2 by 5, it becomes
20x + 16y = 38
20x + 25y = 51.5
Subtracting, it becomes
- 9y = - 13.5
y = - 13.5/-9
y = 1.5
Substituting y = 1.5 into equation 1, it becomes
5x + 4 × 1.5 = 9.5
5x + 6 = 9.5
5x = 9.5 - 6 = 3.5
x = 3.5/5 = 0.7
Answer:
Total there are 2 king of red color out of 52 cards. Therefore, the probability of getting a king of red color will be 2/52 or 1/26. Three cards are drawn from the top of a 52 card playing deck.
Hii I hope this helps! :)
Translation: It’s a transformation that moves every point in a figure the same distance in the same direction.
Rotation: It’s a a transformation that turns a figure about a fixed point.
Reflection: It’s a transformation that takes a shape/preimage and flips it across a line called the line of reflection to create a new shape/image.
Two complementary angles sum is 90 degrees.
Angle 1 = x
Angle 2 = 2x ( two times angle 1)
Equation: x + 2x = 90
Solve:
Combine like terms:
3x = 90
Divide both sides by 3:
X = 90/3
X = 30
Angle 1= 30
Angle 2 = 60
Sin (90-x) = cos x
so x = 40
