Answer: 16
Step-by-step explanation:
Because the Y is 0 for both, you can simply draw a line graph with one point at 15, and the other at -1. The difference between 15 and -1 is 16. Or ABS(15-(-1))=16
Student A starts with $100 in the bank and makes $5 a day. Student B starts with $50 and makes $7 a day. Assuming the students save their money, when will they have the same amount of money ?
A system of equations is good for a problem like this.
Let x be the number of student tickets sold
Let y be the number of adult tickets sold
x + y = 200
2x + 3y = 490
x = 200 - y
2(200 - y) + 3y = 490
400 - 2y + 3y = 490
400 + y = 490
y = 90
The number of adult tickets sold was 90.
x + 90 = 200 --> x = 110
2x + 3(90) = 490 --> 2x + 270 = 490 --> 2x = 220 --> x = 110
The number student tickets sold was 110.
Option B:
ASA congruence
Solution:
Step 1: Given
Step 2: Given
Step 3: Given
(Included side)
Step 4: All right angles are congruent.
(Angle)
Step 5: By vertical angle theorem
(Angle)
Step 6: By ASA congruence
QU and RU are included side of corresponding angles.
Therefore by ASA congruence rule,
Option B is the correct answer.
Hence proved.
