Find the values of x and y.
A. x = 129, y = 51
B. x = 51, y = 129
C. x = 66, y = 17
D. x = 17, y = 66
Answers
Answer:
C x = 66 : y = 17
Step-by-step explanation:
since 2x - 3 and 129 are vertical angles you know that they are equal so you can make the equation 2x -3 = 129 you add 3 to both sides to get 2x = 132 then you decide by 2 to get x = 66

2x−1/15 = 7/3
Answers
Answer:
x=18/15, or 1[tex]\frac{1}{5}[/tex]
Step-by-step explanation:
Convert 7/3 into a fraction with denominator 15. Multiply both sides by 5 to get 35/15. Now, we add 1/15 to it to cancel out on both sides.
Our new equation is 2x=36/15
Divide by 2 on both sides
x=18/15, or 1[tex]\frac{1}{5}[/tex]

At the Royal Dragon Chinese restaurant, a slip in the fortune cookies indicatos a dollar amount that will be subtracted from your total bill, A bag of 10 fortune cookies is given to you from which you will select one. If seven fortune cookies contain "$1 off," two contain "$2 off," and one contains "$6 off," determine the expectation of a selection.
Answers
Answer:
We can expect $1.7 off
Step-by-step explanation:
We are given 10 fortune cookies out of which
$1 off = 7 cookies
$2 off = 2 cookies
$6 off = 1 cookie
Probability
A = drawing $1 off cookies P(A) = 7/10
B= drawing $2 off cookies P(B) = 2/10
C= drawing $6 off cookie P(B) = 1/10
Expectation = 1*7/10 + 2*2/10+ 6*1/10
= 7/10 + 4/10 + 6/10
= 17/10 = $1.7 off

10. Which of the following sets of numbers represents a Pythagorean
Triple?
A {10, 5, 12}
B {2,4,5)
C {1,2,3}
D {14, 48, 50 }
Answers
Answer:
D
Step-by-step explanation:
Trust me I used a calculator and and different one to make sure my answer was correct.
{14, 48, 50} represents a Pythagorean Triple, hence option (D) is correct.
If three sides of any triangle are a, b and c and c is the largest one then the condition that a, b and c will form a Pythagorean triplet is as:
c² = a² + b² -----(1)
An option which will satisfy the condition (1) will form a Pythagorean Triple.
Let's check for all the given options:
A) {10,5,12}
Since, 12 is the largest number out of three.
Therefore, c = 12, a = 5, b = 10
Now,
a² + b² = 5²+10²
a² + b² = 25+100
a² + b² = 125
a² + b²≠ 15²
a² + b²≠ c²
Hence, {10, 5, 12} will not form a Pythagorean Triple. Option (A) is incorrect.
B) {2,4,5)
c = 5, a = 2, b =4
a² + b² = 2²+4²
a² + b² = 4+16
a² + b² = 20
a² + b² ≠ 5²
Hence, option (B) is also incorrect.
(C) {1,2,3}
c = 3, a = 1, b = 2
a² + b² = 1²+2²
a² + b² = 1+4
a² + b²= 5
a² + b² ≠ c²
This is also not forming a Pythagorean Triple, that is why incorrect.
(D) {14, 48, 50}
c = 50, a = 14, b = 48
a² + b² = (14)²+(48)²
a² + b² = 196 +2304
a² + b² = 2500
a² + b² = (50)²
a² + b² = c²
This satisfies the condition (1) hence, it is forming a Pythagorean Triple.
This option is an appropriate choice.
Hence, option (D) is correct, that means {14, 48, 50} represents a Pythagorean Triple.

Ahmed is riding the elevator in a building. The building has floors above and below ground level. Ahmed uses the expression below to describe his movement.
Answers
Answer:
Step-by-step explanation:
The question is incomplete. Here is the complete question
Ahmed is riding the elevator in a building. The building has floors above and below ground level. Ahmed uses the expression below to describe his movement. 6 + (–8) Which statement could describe Ahmed’s movement?
Given the expression
6+(-8)
Let's denote upward movement in the elevator as positive and downward movement as negative.
+6 means that Ahmed rides 6 floors above in the elevator (since +be means upward movement in the elevator)
-8 means that from that 6th floor, he then moves 8 floors downwards in the elevator. In other to determine the floor Ahmed is, we can evaluate the given expression:
= 6+(-8)
Note that -×+ = -, hence the expression becomes;
= 6-8
= -8+6
= -2
This means that Ahmed is 2 floor below or down the elevator.
Answer: He moved 6 floors up, then moved 8 floors down. So he is now 2 floors below ground level.
