Your equation states y = 4(-1) + 3
Since the parentheses touch the number 4 which means you multiply, we will start with that first.
4 × -1 or 4(-1) (it means the same thing) would be -4
Now let us combine the equation.
y = -4 + 3
The addition property is included now,
-4 + 3 = -1
Therefore, your answer would be y = -1
Hope this helped! :D
It is not possible to select a single group from the primary school, since being a single group it could not in any way represent the entire primary school.
Choosing a group would provide the average height for that group, not the entire primary.
Assumptions can be made that the course of half of the primary would theoretically give us a more accurate representation, but the objective is to select a number of students from each course and there would be a representative sample of the entire primary.
Answer:
After 7 minutes both the tanks will have the same amount of water.
Step-by-step explanation:
The water is filling in a tank at the rate of 75 L/mins from an initial 550 L of water and water is removing from another tank at the same rate from the initial 1600 L of water.
Let us assume that the same amount of water will be there in both the tanks after t minutes.
Therefore, 550 + 75t = 1600 - 75t
⇒ 150t = 1050
⇒ t = 7
Therefore, after 7 minutes both the tanks will have the same amount of water. (Answer)
A) 5/10 = (5/10)*(10/10) = 50/100
b) 47/100 +50/100 = (47+50)/100 = 97/100
