Alright. So the problem is
10*12+-15/5+2(9-4)
Lets break down what we can for now
First focus on parenthesized, multiplying, and dividing in the problem.
10*12=120 15/5=3 (9-4)=5
120+-3+2*5
So the next step, we see 2*5 and a negative -3 on top of a positive symbol.
2*5=10
120-3+10
Now subtract from the left to the right and get your answer.
120-3=117
117+10=127
Answer: A
Step-by-step explanation: This is because the first line goes forward 4.5 and the second line moves it back 2.5 and 4.5-2.5 is 2 which is the endpoint of answer a
Answer:
He drove 120 km
Step-by-step explanation:
We know that 1 hour of driving is equal to 80 km. We need to find out for 1.5 km. First, we need to know how much km for 1/2 of an hour. Which will be 40, because 80/2=40. Then we add up the 40 to the 80, and we get 120 km in total.
