Trinomial: there are 3 variables
Answer:
45 total riders
Step-by-step explanation:
Given the equation, t = 5s, where,
t = total riders
s = number of bus-stops
If it picked up 9 bus-stops, to find the total number of riders, substitute s = 9 into the equation.
Thus:
t = 5(9)
t = 45
Answer:
D. 15G > 9
Step-by-step explanation:
Given: G = 3/5
Here we have to check each options and find which is true.
Let's start from A.
G - 1 > 2/5
G > 2/5 + 1
G > 7/5 is not true.
B. -10G > 6
Dividing both sides by -10 , we get
G < -6/10
G < -3/5 Is not true.
C. 1 2/5 + G > 3
Now convert 1 2/5 to improper fraction.
1 2/5 = 7/5
7/5 + G > 3
G > 3 - 7/5
G > (15 - 7)/5
G > 8/5 is not rule.
D. 15G > 9
Dividing both sides by 15, we get
G > 9/15
Now we have to simplify 9/15
G > 3/5 which is true.
Answer: D. 15G > 9
Thank you.
Let the number be a
6a - 20 = 3a + 4
Group like terms
6a - 3a = 20 + 4
3a = 24
divide through by 3
a = 8
Therefore the number is 8
