Problem:
Given that a*b = 2ab - 3b. Determine 2*(3*5)
Step-by-step explanation:
First we find 3*5 using rule a*b = 2ab - 3b.
3*5=2(3)(5)-3(5)
3*5=30-15
3*5=15
Now we are left with 2*15 in which we will still use the rule a*b=2ab-3b.
2*15=2(2)(15)-3(15)
2*15=60-45
2*15=15
Therefore, 2*(3*5)=15.
The denominator is 40
10-3=7 (number of students in the band who do not ride the bus)
7/40=0.175
0.174*100=17.5% chance
Hope this helps!
Answer:
the first one
Step-by-step explanation:
(-5+5) will equal 0. Because of the zero property no matter what you multiply it by it will equal 0. Same thing with (9-9)
Answer:
The answer is 120km.
Step-by-step explanation:
We can set up the proportion that for every 54 liters, the car will go 648km.
This means that 54/648 = petrol/distance.
If we substitute 10 for petrol, we get the equation:
54/648 = 10/x.
We can cross multiply and solve that x = 120.
