Divide 10/12 by two same thing with 4/6 and you should get the simplified fractions
Answer:
Monthly fare of employer = $ 10
Fare for swiping = $ 0.15
No. of times swiped = 40
Total cost spent = $10 + $ 0.15
= $ 10.15
Total cost of swipe = $ 0.15 × 40
= $ 0.60

year, the average math SAT score for students at one school was 475. The
headmaster then introduced a new teaching method hoping to improve scores. This
year, the mean math SAT score for a sample of students was 491. The headmaster
concluded that the new teaching method produces higher SAT scores. The problem
with reporting results this way is voluntary response. The information of how
the teaching method isnot mentioned.</span>
Answer:
Step-by-step explanation:
The sum of the angles in a triangle is 180 degrees.
One of the angles of a triangle measures d°, another measures (3d)°, and the third measures (5d + 54)°. The equation becomes
d + 3d + 5d + 54 = 180
9d + 54 = 180
9d = 180 - 54
9d = 126
d = 126/9
d = 14
First angle is 14 degrees
Second angle is 3 × 14 = 42 degrees
Third angle is 5 × 14 + 54 = 124 degrees
