Commutative property of multiplication is what the property is called.
A * B = B * A
Where both 'A' and 'B' are expressions.
Hope this helps!
Answer:
Step-by-step explanation:
We want to simplify:
This is the same as:
Now let us convert the mixed numbers to improper fractions.
We multiply by the reciprocal of the second fraction to get:
Cancel out the common factors to obtain:
Answer:
Answer:
6 days
210 pages
Step-by-step explanation:
As stipulated by the question, let the number of days Amir has been reading be x and the number of pages he had read to be y.
Now since he reads 35 pages per day.
Then mathematically;
y = 35x
For Jesse, He started reading a day before, this means that the number of days he had read would be x + 1. Since he reads 30 per day, the total number of pages he would have read is 30(x+1)
To find the number of days which is x, we have to assume that at a point in time, the number of books they would have read would be the same meaning that
Also; y = 30(x + 1)
Equating the two situations
35x = 30(x + 1)
35x = 30x + 30
35x -30x = 30
5x = 30
x = 30/5
x = 6 days
This means that it will take Amir 6 days to catch Jese.
The number of books they would have read by then is y = 35x = 30(x + 1)
= 35 * 6 or 30(6+1)
= 210
Step-by-step explanation:
The number 1000 has three zeros which will move the decimal three times. But what in direction?
Well, when we multiply a number by 10, we move the decimal one place to the left.
So, the answer is three places to the left.
Step-by-step explanation:
7x + 8y = -12
8y=-12-7x
y=
