Answer:
Step-by-step explanation:
1) Distance covered by motorcycle = x
y = 50 + (x -2)*10
2)Distance traveled = 5 km
y = 50 + ( 5-2) *10
= 50 + 3*10
= 50 + 30
= 80
Seth will be paid Php 80
3) y = 120
50 + (x - 2)* 10 = y
50 + (x -2) *10 = 120
50 + 10x - 2*10 = 120
50 + 10x - 20 = 120
30 + 10x = 120
10x = 120 - 30
10x = 90
x = 90/10
x = 9
A passenger can travel 9 km.
4)y = (x - 2)*10
y = 10x - 20
20 + y = 10x
20 = 10x - y
10x - y = 20 {Ax + By = C form}
Answer: The probability of drawing a heart out of the deck is 13/52, or 1/4. The probability of drawing an even number as card #2 (c∈{2,4,6,8,10}) for any suit is 20/51, except when the first card drawn is an even heart, then the probability of the second draw is 19/51.
Step-by-step explanation:
Answer:
(49 - 29) + 1 =(50 - 29)
Step-by-step explanation:
The 20 comes from the subtraction of 29 in both sides of the previous step equality. In the following, I transcript the complete procedure and I add the step that you need to understand why 20 appears (in bold numbers):
29+20=49
49+1=50
(49 - 29) + 1 =(50 - 29)
20+1=21
50-29=21
hence, it was only nesseraty to subtract 29
